Abstract

Objective: The purpose of this clinical study was to provide an evaluation of the agreement between the virtual occlusal scheme designed by a computer-aided design and computeraided manufacturing (CAD-CAM) software program, and the occlusal scheme obtained clinically on the definitive prosthesis assessed with articulating paper.

Materials and methods: The virtual occlusal scheme design of 20 single monolithic crowns and their adjacent teeth were obtained using an intraoral scanning system (IOS) in 17 participants. These registrations were compared with conventional occlusal records obtained by articulating paper applied in 2 stages: first with 200-μm blue film and the second with 12-μm metallic red articulation tape. The analysis included both the quantity and the quality of the contacts of the conventional occlusal records referred to as the standard method. For accuracy analysis, virtual record sensitivity was calculated per crown as the percentage of true positive virtual contacts of the actual contacts identified by articulating paper.

Results: The virtual record sensitivity was 98.5 (95% confidence interval 96 to 100) for the crowns and 95 (95% confidence interval 85 to 100) for the adjacent teeth. The virtual record specificity was 88.6 (95% confidence interval 82.4 to 94.8) for the crowns and 82.6 (95% confidence interval 77.5 to 87.6) for the adjacent teeth. The agreement between the clinical and virtual contact intensities on the crowns was 83 (95% confidence interval 73 to 93) and 67.3 (95% confidence interval 56 to 78.7) for the adjacent teeth. The positive predictive value was 72.83 (95% confidence interval 60 to 86). The negative predictive value was 100% (95% confidence interval 100 to 100).

Conclusions: The intraoral scanning system provided clinically sufficient sensitivity and specificity for identifying occlusal surface contacts of monolithic crowns. A slight decrease was detected in the system’s sensitivity and specificity identifying contacts on adjacent teeth.

Abstract
Objectives: The aim of this study was to evaluate the survival rate, technical and biological complications, and patient-reported outcome measures (PROMs) of full mouth rehabilitation with minimally invasive glass-ceramic restorations after a minimum of 1.5 years of clinical service.

Materials and methods: 20 individuals (12 females, 8 males) had received full mouth toothsupported with minimally invasive glass-ceramic restorations during the years 2009 – 2017 and participated to the follow-up visit. Full dental and periodontal examination was completed, and all the restorations were evaluated according to United States Public Health Service (USPHS) criteria. KaplanMeier was used for analysis of the survival time.

Results: Study participants had 439 minimally invasive restorations made from lithium disilicate reinforced glass-ceramic (79.7%), feldspathic porcelain (17.5%) and leucite reinforced glass-ceramic (2.7%). The restoration design included overlays (35.3%), full-contour restorations (31.2%), veneers (27.8%), tabletops (4.6%) and inlays (1.1%). The mean follow-up time from insertion to the examination visit was 4.5 years (1.5–12.4). Five patients lost altogether 13 restorations during the follow-up time. The resulting estimated cumulative Kaplan-Meier 5-year survival rates were 96.6% on restoration level and 86.4% on patient level. The most common complications on restoration level were of technical nature and included marginal discoloration (11.4%) and occlusal wear (14.1%). Larger chippings were seen in 1.1% (n=5) of the restorations. Biological complications (on restoration level) were not common (4.3%). Relatively high amounts (50.4%) of bleeding on probing was seen, which was not associated to the amount of plaque (17.4%). According to the PROMs questionnaire, the patients were very satisfied with esthetics (VAS 9.5) and function (VAS 9.3) of the restorations. Women rated their oral health situation significantly better than men (p=0.03).

Conclusions: Minimally invasive full-mouth rehabilitation with glass-ceramic restorations seem to be a predictable treatment option with high survival rates, few complications and high level of patient satisfaction.

Abstract

Objective: The aim of this study was to evaluate the mean height and maximal height loss of canine restorations in patients after complete prosthetic rehabilitation due to severe tooth wear with lithium disilicate ceramic over 3 years.
Materials and Methods: 40 canine restorations were analyzed in 10 patients as part of a clinical study with complex rehabilitations made of monolithic lithium disilicate ceramic (IPS e.max Press, Ivoclar, Schaan, Liechtenstein). Data was collected at annual recall appointments with polyether impressions and digitalization of the gypsum cast using a laboratory scanner. The obtained datasets (n=104) were exported to a surface analysis software (GOM Inspect Professional, Braunschweig, Germany) and were individually overlaid over the baseline dataset. The superimposition error of 10μm was determined as exclusion criteria for further data analysis (n=16). The mean and maximal height loss of occlusal-contact areas were quantified. Kruskal-Wallis test was used to determine significant differences between groups regarding time, as the data showed significant deviations from the Gaussian distribution (Shapiro-Wilk test).
Results: Mean/Maximum wear rates resulted as following: for the first year 33.2±21.5/97.7±63.5 μm/year, for the second year 22.7±19.5/57.9±37.0 μm/year, for the third year 18.1±11.5/56.9±40.7 μm/year. Both groups showed significant differences regarding time, with decreasing values over time. Conclusions: This data gives first insights into clinical wear of canine restorations made of monolithic lithium disilicate ceramic. This study showed comparatively low restorations wear rates, with significant differences between groups with rising time in situ. Highest mean and maximum wear rates could be observed for the first year of clinical service. Generally, wear of canine restorations should be taken into account when choosing the material for prosthetic rehabilitation, as the canine guidance ensures adequate function in dynamic occlusion and reduces shear forces on posterior teeth and restorations.

Abstract

Objectives: To identify possible factors that may modulate the oral health-related quality of life (OHRQoL) in patients with maxillary implant-overdentures (IOmx).

Materials and Methods: 70 patients wearing IOmx were recruited by a consecutive sampling procedure for this cross-sectional study. Participants were classified into 2 balanced groups according to their partnership status (n= 35 each): Group-1 (patients with partner), Group-2 (patients without partner); and concerning their gender (n= 35 each): Group-A (women), Group- B (men). QoLIP-10, QoLFAST-10, and QoLDAS-9 questionnaires were responded, and patients were clinically examined. Sociodemographic, and prosthesis-related data were gathered. Descriptive statistics were calculated. Potential QoL modulators were assessed using non- parametric probes (Chi-square, Kruskal-Wallis, and Mann-Whitney U tests; a= 0.05).

Results: The QoLDAS-9 scale discriminated the study groups (p< 0.05). The partnership status significantly affected the item 7 of the QoLDAS-9 index (Socio-dental dimension), the Group-2 being more satisfied with the size of the prosthetic teeth compared to Group-1 (p= 0.005).

The gender modulates the QoLDAS-9 total score, conferring to Group-A better self-perception with the IOmx (p= 0.000), concretely about its Psycho-facial (p= 0.000) and Interactive (p= 0.016) domains. Group-A referred better wellbeing with the IOmx when speaking (item 9, Performance subscale) with the QoLIP-10 (p< 0.05).

The partnership status affected the QoLFAST-10 Social dimension (p< 0.02) and total score (p<0.05), the volunteers without partner being more satisfied.

The retention system did not impact the QoL perception, while the bar worsen the appearance of the oral mucosa (p= 0.05). The OHRQoL increased as the retention, stability, and aesthetics of the prosthesis improved (p< 0.05).

Conclusions: Overall, IOmx wearers have a satisfactory OHRQoL. The IOmx retention system does not influence the OHRQoL. Women and patients without partner are more satisfied with the treatment. A better OHRQoL is perceived when the retention, stability, and aesthetics of the restoration are suitable.

Abstract

Background: The evaluation of volumetric stability of peri-implant tissue is becoming more and more important in implant therapy because it is invaluable for assessing the long-term success of interventions. In the literature, many different methods have been proposed for evaluating tissue changes over time following different implant and tissue regeneration procedures. Technological progress offers new 3-dimensional methods for visualising and evaluating volumetric changes based on optical scans.

Aim: The aim of this study was to validate an innovative 3D volumetric method proposed by Lee et al., 2020, for evaluating tissue changes, by comparing the results of this method in which the scanned peri-implant surfaces were transformed and analysed as 3D objects, with the results reported by an existing method based on the calculation of the mean distance between measured surfaces. The null hypothesis was that the two methods provide equivalent results. Additionally, the present study evaluated peri-implant tissue changes 5 years after single implant placement in the aesthetic zone.

Materials and Methods: Both methods were applied to 11 oral casts taken from 11 patients at crown placement at the implant site (6 upper central implant sites, 5 upper lateral sites) and at follow-up examinations 5 years later. The methods are based on digital workflows in which the master and 5-year follow-up dental casts are scanned and the resulting STL (Standard Tessellation Language) files superimposed for three regions of interest (mesial papilla, central area, distal papilla). The volumetric changes reported by the 3D method of Lee et al. and mean distance method were calculated and compared using the Spearman Rho correlation coefficient (significance level p<0.01) and the Wilcoxon signed-rank test (significance level p<0.05). The correlation between the two sets of measurements was very high (Spearman Rho correlation coefficient = 0.885). The new volumetric method indicated a mean volume loss of 2.82mm3 (SD: 5.06), while the method based on the measurement of mean distance showed a mean volume loss of 2.92mm3 (SD: 4.43, Wilcoxon signed-rank test result: p=0.77).

Results: No statistically significant difference was found. The two methods gave equivalent results, and the null hypothesis was not rejected.

Conclusion: The new volumetric method was validated and can be considered a valuable and trustworthy tool.

Abstract

Objectives. This study aims to evaluate the trueness of occlusion, focusing on error propagation from intraoral scanning (IOS) to additive manufacturing (AM, or 3D printing).

Materials and methods. Custom reference models were additively manufactured, articulated, and scanned using a Coordinate Measurement Machine (CMM, n=1). Positive/negative occlusal contacts were recorded. Digital impressions were collected from the reference models using a Trios 4 (3Shape) IOS with “Adjust for contacts” feature enabled (IOS_Ad, n=10) and duplicated without this feature (IOS, n=10). IOS_Ad scans were processed to create test models using MAX UV385 (Asiga) and NextDent 5100 (3DSystems) AM devices. Conventional workflow was replicated with VPS impressions and Type IV stone. AM and stone models were articulated and digitized with E4 (3Shape) in three occasions: with/without AM positioning pins and after manual occlusal correction (Co). Inter-arch distances and 3D contact area were measured in digital models and compared. Statistical tests used were Shapiro-Wilk, Levene’s, Welch’s t-test, and 2-way ANOVA (α=.05).

Results. IOS_Ad group had higher 3D contact trueness than IOS, Stone, Stone_Co (p<0.05). “Adjust for contacts” feature increased the 3D contact trueness (p=0.00, ∆=34.51mm2 ). Effect of manual occlusion correction of stone casts was insignificant (p>0.05). Digital impressions had higher occlusal trueness than AM models after removal of the pins (p<0.05). Introduction of errors was mostly higher in AM rather than IOS (p<0.05). 3D contact area analysis showed similar deviations of AM and stone models (p>0.05).

Conclusions. The study partially approved the null hypothesis, indicating that AM and stone models have a similar trueness of occlusion. The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the study.

Abstract

Objectives: To evaluate the fracture resistance of zirconia overlays or occlusal veneers with various preparation designs, considering the presence or absence of endodontic access.

Materials and Methods: Ninety translucent zirconia (5Y-PSZ) overlay restorations (n=15/group) were fabricated in different preparation designs with and without endodontic access and were categorized into six groups: group 1 (M4), with chamfer margin 4 mm above the gingival level; group 2 (M4End), with chamfer margin 4 mm above the gingival level and endodontic access, group 3 (M2), with chamfer margin 2mm mm above the gingival level; group 4 (M2End), with chamfer margin 2 mm above the gingival level and endodontic access; group 5 (nM), overlay with no chamfer margin; and group 6 (nMEnd), overlay with no margin and endodontic access. Restorations were bonded to mandibular first molar resin dies, and the groups with endodontic access were sealed with flowable resin composite. All restorations underwent 100,000 cycles of thermal cycling between 5°C and 55°C, followed by loading until fracture. Maximum load and fracture resistance were recorded. ANOVA with Tukey post-hoc tests were used for statistical comparison (α<0.05).

Results: The fracture resistance among the overlays of different designs with and without endodontic access varied (p <0.001). Overlays with margin located 2 mm above the gingival margin exhibited the highest fracture resistance, both without group 3 (M2) and with group 4 (M2End) endodontic access. This was followed by overlays with margin 4 mm above the gingiva without group 1 (M4), group 5 (nM), and group 6 (nMend). Group 2 (M4End) the overlays with finish line at 4 mm and endodontic access displayed the lowest fracture resistance values.

Conclusions: Zirconia overlay restorations with endodontic access have lower fracture resistance than those without endodontic access. Overlay with margins closer to the gingival level display higher fracture resistance compared to those with high chamfer and no chamfer margin.

Abstract

Objectives: It is claimed that a reliable bond is created by effectively cleaning the contaminated surfaces of restorations with proper surface cleaners. This study aimed to evaluate the effect of different surface cleaning methods on the bonding of resin cement to zirconia and zirconia-reinforced lithium silicate ceramic.

Materials and methods: 54 slices obtained from zirconia-reinforced lithium silicate (ZLS) (Vita Suprinity) and zirconia (ZIR) (IPS e.max ZirCAD) blocks. The final thickness of the specimens set to 1 mm ±0.02 mm. The specimens divided into nine groups both for ZLS and ZIR: non-contamination, saliva – air/water spray, saliva – Ivoclean, saliva – Katana Cleaner, light body – air/water spray, light body – Ivoclean, light body – Katana Cleaner and light body – alcohol. X-ray photoelectron spectroscopy (XPS) analysis performed to determine chemical change to each group; SEM analysis performed for microscopic surface changes. The resin bond strength values were obtained by performing the micro-shear bond strength (mSBS) test. The specimens examined with a stereomicroscope to investigate the failure types.

Results: Contamination with saliva and light body silicone decreased the bond strength significantly (p<0.05). The mSBS value of ZLS-non contamination group was the highest (27.69±7.1) and the mSBS obtained after decontamination of the saliva with the Katana Cleaner (15,32±7,5) was statistically higher for ZLS specimens (p<0.001). For ZIR specimens highest mSBS value was obtained with Katana Cleaner (18.95±6.9, p=0.803). The highest mSBS values for ZLS and ZIR specimens found after decontamination of the light body silicone with alcohol (23.26±3.1, p=0.220; 19.77±8.6, p=0.729). According to XPS analysis, Ivoclean removed element C better than other cleaners from the surface, similarly alcohol removed element Si better than other cleaners.

Conclusion: Katana Cleaner could be used as a surface cleaner after contamination with saliva, and alcohol found to be more effective after contamination with light body silicone. Keywords: Cleaner; Contamination; Saliva; Zirconia; Zirconia-Reinforced Lithium Silicate

Abstract

Objectives: Complete edentulism impacts patients’ quality of life. Denture experience is crucial for analyzing the impact of denture usage. The main purpose of this study was to analyze the effects of denture experience, and demographics on oral health-related quality of life.

Materials and Methods: In this study, 352 patients were included who were treated with maxillary and mandibular complete dentures by a single clinician within four years and wore the dentures for a minimum of one year. Participants were evaluated in terms of age, gender, systemic diseases,mdenture experience, clinician advise, and wearing dentures at night. Answers to the Geriatric Oral Health Assessment Index and Oral Health Impact Profile questionnaires were collected, and a statistical analysis was performed.

Results: Both scales were found to be reliable, and a high degree of correlation was detected (p = 0.00). According to Oral Health Impact Profile-14, the experience related to psychological discomfort (p = 0.036), social disability (p = 0.01), and handicaps (p = 0.00) while the Geriatric Oral Health Assessment Index found that the denture experience affects the behavioral impacts (p = 0.00). It was determined that factors of age, denture experience, clinician advice, and wearing dentures at night influenced oral health-related quality of life.

Conclusions: The findings of this study indicated that denture experience considerably improved patients’ oral health-related quality of life. Also, Oral Health Impact Profile-14 and Geriatric Oral Health Assessment Index showed high levels of validity and reliability for edentulous patients.

Abstract

Objectives. The objective of this study is to compare, in vitro, bite registration accuracy between three different methods using IOS.

Materials and Methods. Maxillary edentulous and mandible dentate models were printed using the Asiga Max UV (Asiga, Sydney, Australia) 3D printer. Four Straumann BLT RC 4.1 mm diameter (Straumann, Switzerland) dental implants were placed in the maxilla model. Scanbodies were attached to the implants. Metrological spheres were attached to both models. Reference scans were obtained using a Nicon Altera (Nikon Metrology, Shinagawa, Japan). Digital impressions were taken with Trios 4 (3Shape, Denmark) intraoral scanner ten times for each model. Additionally, three types of digital bite records were taken for each pair of scans (Fig 1-3): The first group of registration was done by acquiring bite scan between buccal aspects of models from one left to right with scanbodies fixed to the upper model (WSB). For the second group, the same protocol for bite registration was applied with the addition of putty silicone (Variotime Easy putty, Kulzer GmbH, Germany) index between two models (WSB silicone). The third group was done according to pre-preparation scanning protocol (Pre-PREP): digital impression was acquired of a prefabricated maxillary removable denture, then the antagonist. Conventional bite registration was acquired. Finally, the denture was cut out of the maxillary scan and rescanned with scanbodies attached to implants. Distances between corresponding spheres were calculated as a way to represent interarch distances. Trueness and precision were calculated for all the parameters measured, and a comparison was made between different bite registration groups.

Results. There were significant differences among the groups three (pre-prep)-two (WSB silicone) and three (pre-prep)-one (WSB) on trueness. Pre-preparation method was more inaccurate than the other two. (Fig. 4)

Conclusions. In this, in vitro, study pre-preparation registration technique was less accurate than using scanbodies with or without silicone index for maxillomandibular relation registration.

Abstract

Objectives: Grade 5 (Ti6Al4V) titanium alloy is widely used in dental abutment types. However, there are not enough studies about activated charcoal toothpaste effects on titanium surfaces although its increasing popularity. The aim of this study was to evaluate the effect of activated charcoal toothpaste usage on the surface roughness of Ti6Al4V.

Materials and Methods: Square shaped specimens (10×10×3mm) were prepared from medical Ti6Al4V alloy using guillotine cutting and the surfaces of them were finished with mirror-polished. Initial Ra values of the all specimens were measured by a contact profilometer. Then, specimens were divided into three groups (N=24, n=8): Unbrushed control group (Ti-C), brushed group with activated charcoal toothpaste (Ti-AC), brushed group with only distilled water (Ti-DW). Brushing simulation was performed using tooth brushing simulator (SD Mechatronic) with forward-backward motion in a linear distance of 5 mm, at speed of 25 mm/s, under 200g pressure for 10000 cycles to simulate 1-year of usage. The
final roughness values of the specimens were measured after brushed. Data were statistically evaluated by paired t-test to evaluate before and after roughness changes in brushed groups and one-way ANOVA and post-hoc Tukey test to comparison all groups (α=.05).

Results: Changes in surface roughness were statistically significant in both Ti-AC and Ti-DW group when compared before and after roughness values by paired t-test (p=.011 and p=.004, respectively). However, when compared independent groups, group Ti-AC and Group Ti-DW were found to be similar (p=.350), and when compared with group Ti-C, there was no statistical difference (p>.164).

Conclusion: Brushing the titanium surface with activated charcoal toothpaste does not produce more significant roughness changes than the effects of brushing itself. Therefore, it can be said that its shortterm use will not cause negative effects. However, further studies are needed to recommend its longterm use.

Abstract:

The manner in which stresses are transferred to the bone surrounding implant-supported or implant-retained overdentures (IOs) is one of the most significant factors in determining their efficacy. The objective of this study is to evaluate the stress on the implant and prosthetic components according to the retention system: locator, ball attachment, bar attachment, and telescopic attachment system.

Material and Method: Using SpaceClaim, 3D finite element models were created to simulate clinical situations. These models included IOs with five distinct attachment systems: locator attachment system, locater R-Tx attachment system, ball attachment system (dimensions and material properties according to Zest Anchors, USA), bar attachment system and the telescopic attachment system (Dimensions and material properties of primary and secondary copings were in accordance with Dentsply, Ankylos Syncone/5°, USA). Each overdenture’s central fossa in the molar region was subjected to a 35N compressive force that was applied in both the vertical and oblique directions. A non-linear static contact analysis was performed to determine the distribution of stress among the various IOs components. Following this, the models were analyzed using the finite element software ANSYS, and the results were displayed using Von Mises stress patterns.

Results: Both oblique and vertical loading substantially increased the maximal von Mises stresses on the implants when they were affixed using the telescopic attachment system. Under vertical loading, the maximal von Mises stresses on the abutment were greater for the ball attachment system, whereas they were greater for the telescopic attachment system under oblique loading.

Conclusions: As clinical tip, bar attachment, locator attachment and locater R-Tx attachment can be considered as a suitable alternative to telescopic attachment system and ball attachment for IOs.

Abstract

Objectives: To evaluate the accuracy of a complete digital workflow utilizing a novel reverse prosthetic scan body, implementing different scan patterns.
Materials and methods: A mandibular cast with 4 multi-unit abutment implant analogs (Screw-Retained Abutments) with adequate antero-posterior spread simulated a common clinical patient situation. This cast served as the master cast and an interim screw-retained prosthesis was fabricated on it. Novel reverse scan bodies were connected to the interim prosthesis and extra-oral scanning was performed with an intraoral scanner and 3 different scan patterns: starting from the occlusal surface of the interim prosthesis (O – group 1), starting from the intaglio (I – group 2), and helix pattern (H – group 3). The produced STL files from the 3 groups were then imported to a computer-assisted design (CAD) software (exocad) and after the digital design, the STL file was exported to a computer-assisted machining (CAM) milling machine generating in total 15 milled prosthesis prototypes per group. Two clinicians assessed the accuracy of fit of each digitally fabricated prosthesis prototype on the master cast, utilizing a screw-resistance test and a subsequent radiographic evaluation. The Fisher’s exact test was used to test the difference between the 3 groups.
Results: Out of the 3 different groups, O group scan pattern led to 100% accuracy of fit, while the prototypes generated from I and H groups led to 80% and 53% accuracy of fit. The results were statistically significant (P=0.008).
Conclusions: Occlusal scan pattern leads to accurately fitting milled prosthesis prototypes after the extra-oral scanning of the interim prosthesis with reverse scan bodies, without intraoral implant data acquisition. Scan pattern has a significant effect in the accuracy of the fit of the full-arch implant supported milled prosthesis prototypes.

Abstract

Materials and Methods: A fabricated model, featuring an implant of the left lower molar tooth, was used in this study. An impression coping from the same manufacturer was attached to the implant and scanned by using high-accuracy industrial scanner (Atos Core 80) to obtain a reference scan. For first group, eight conventional custom open trays were fabricated using a light-cured base plate (Arasta Lc) with a 2 mm layer of wax (Great Dental Wax) applied to the model. For second group, eight custom open trays were produced through a 3D printer (Primeprint, Dentsply Sirona) through a dental design program (InLab SW, Dentsply Sirona). A total of 16 impressions were taken from the models in which impression copings were placed by using additional silicone impression material (Elite HD+, Zhermack SpA). Afterwards, the analogues were placed in the impression and plaster models were obtained. All of the models were scanned with a laboratory scanner (InEos X5, Dentsply Sirona). The digitally obtained STL (D-STL) data and conventionally obtained STL (C-STL) data were evaluated as two separate groups. Trueness values were obtained by measuring the deviation of each group from the reference model. Independent t test was used to compare results between two tested groups. (α=.05)

Results: Compared to the reference model, the D-STL group (43.25 ± 8.18) demonstrated a statistically significant closer proximity to the reference model than the C-STL group (67.75 ± 8.54). (p<.001)

Conclusion: Within the limitations of this study, the findings suggest that 3D-printed custom open trays have promising accuracy for single implant impressions. Further research is warranted to validate these results and explore the potential benefits of utilizing this technology in clinical practice.

Abstract

Objectives. The impact of the pandemics on the oral health of the edentulous elderly is still unknown. Understanding the cause-and-effect relationships may allow individualized adjustment of oral care recommendations during Covid-19 disease. The study’s objective was to compare oral health during hospital treatment due to adverse Covid-19 among edentulism and dentate patients.

Material and Methods. One-hundred and twenty patients (mean age 74.4±15.4; male n=50/female n=70) were examined in the acute phase of Covid-19 during hospital treatment. The condition of oral mucosa (BRUSHED and Beck scores), blood biochemical parameters (D-dimer, C-reactive protein CRP, lymphocyte, interleukine-6 IL-6) and clinical status (respiratory failure as pneumonia and Covid-19 symptoms severity) were compared between dentate and edentulous patients. All results were considered significant at p < 0.05.

Results. All patients presented characteristics of the dental plaque retention (83.4%), xerostomia (74.2%), oral mucosa inflammation (80.8%), angular cheilitis (53.3%), hemorrhage (21.7%) with a higher incidence of harmful oral conditions among edentulous patients. This group had also higher BRUSHED and Beck scores indicating a need for oral care every 8 hours. Multiple regression selected the following risk predictors for pneumonia as IL-6, CRP, PCR index and Beck score (p<0.001). Patients who received oxygen therapy with face masks had more often angular cheilitis and debris (p=0.025, p=0.035).

Conclusions. COVID-19 hospitalised patients with severe symptoms crossing with poor oral health-related conditions, particularly among edentulous patients. For Covid-19 management, in order to inhibit extra- and intra-oral complications, it is recommended to adjust oral hygiene procedures, including antibacterial, protective, moisturising agents after professional oral health examination.

Abstract

Objectives: To compare the diagnostic performance of a Deep-Learning Convolutional Neural Network (DL-CNN) in terms of object detection and segmentation following two different training approaches.

Material and Methods: A total of 300 orthopantomographies (OPGs) were randomly selected for this study. To establish ground truth, images were manually annotated by a single previously trained and calibrated operator using an Artificial Intelligence training tool (COCO Annotator v.11.0.1). Annotating classes included: maxilla, mandible, maxillary sinus, inferior alveolar nerve, tooth, both plastic and metallic restorations, crowns and pontics, root canal treatments and
implants. The full dataset was divided into training and validation subsets and were used to train the same neural network for object detection (YOLOv5 Small) and segmentation (YOACT ++) following two different approaches: a) including all annotated classes at once (AC) and b) separating tooth classes (TO) from the rest (RC). Validation-phase performance analysis for object detection was calculated using Mean Average Precision (mAP) at two confidence levels intervals (0-0.5 and 0.5-0.95), F1 Curve and Confusion Matrix. For object segmentation, instead, only mAP at both before-mentioned intervals was calculated for task performance evaluation.

Results: Object Detection mAPs (0-0.5 and 0.5-0.95) for both first and second training strategies were as follows: AC mAP (0-0.5)=0.36, AC mAP (0.5-0.95)=0.22; TO mAP (0-0.5)=0.99, TO mAP (0.5-0.95)=0.67; RC mAP (0-0.5)=0.65, RC mAP (0.5-0.95)=0.39. Object Segmentation mAPs for both first and second training strategies were as follows: AC mAP (0-0.5)=0.34, AC mAP (0.5-0.95)=0.19; TO mAP (0-0.5)=0.38, TO mAP (0.5-0.95)=0.16; RC mAP (0-0.5)=0.30, RC mAP (0.5-0.95)=0.16.

Conclusions: Second training strategy described in this study should be considered for achieving better results in object detection tasks. For object segmentation, albeit more training data is needed in order to increase software’s precision, first training approach seems to be the best choice in case of developing a DL-CNN for diagnostic purposes.

Abstract

Objective: The aim of this systematic review is to present a thorough review of the literature regarding the correlation between the presence of effusion on the magnetic resonance (MRI) imaging and the clinical presence of pain, in a homogeneous group of patients with a temporo-mandibular disorder (TMD).

Materials and Methods: From January to February 2023 a systematic review of literature was performed on the main platforms for scientific research (PubMed, Scopus). This analysis follows a PICO model in order to select those articles which assessed the relationship between temporomanndibular joint effusions in the MRI and clinical pain in TMD patients. The review follow the PRISMA guideline in the selection of the articles.

Results: The MeSH terms used for the research were “tmj AND mri”. For this search a total of 2714 articles were initially retrieved. Only 13 of these articles answered the research question. In 7 articles a relationship between effusion and pain was found; 4 found a relationship between pain and disk displacement (DD); 7 articles found a relationship between effusion and disk displacement (DD) 1 study though stated that there was no correlation between effusion and disk displacement (DD).

Conclusions: The literature clearly suggests a correlation between the presence of effusions and clinical pain in TMD patient. Furthermore correlations were found between effusion and disk displacement (DD) and pain and disk displacement (DD).

Abstract

The aim of the present study was to evaluate shear bond strength of two different types of resin based luting cements to CAD/CAM resin composite block before and after dynamic-aging procedures. Forty CAD/CAM resin composite blocks (Cerasmart 270, GC) with 2-mm thickness and cylindirical specimens (3,6 mm diameter, 5 mm height) were prepared using light-cure resin composite. CAD/CAM specimens divided into 2 subgroups depending on aging procedure (n=20/group). Then the specimens subdivided into 2 groups (n=10/group) based on the resin luting cement types either dual-cure composite resin luting cement (RelyX Universal, 3M-ESPE) or dual-cure self adhesive resin cement (GCem Link Force, GC). Surface treatment protocols are applied to the CAD/CAM blocks and composite resin blocks. After applying universal adhesive agent (Scothcbond-Universal-Plus,3M-ESPE), in order to simulate clinically relevant luting cement thickness, selected cements were applied to between the inner surface of CAD/CAM specimens and resin composite cylindirical specimens with finger pressure. Polymerization of dual-cure luting cements were achieved using high-power LED-LCU (D-Light Pro,Gc) through the outer surface of CAD/CAM specimens for 40-seconds light irradition time. After polymerization, the specimens were stored for 24-hour in water at 37oC. Twenty specimens were thermocycled by 5 oC-55oC for 10000 cycle. Other twenty specimens were connected to the universal test machine for to evaluate bond strength of test specimens using 1 mm/min crosshead speed until bond strength failure. Dynamic-aged specimens were subjected to the same procedure. Considering before and after dynamic-aging, two-way ANOVA showed that, there were no statistically significant difference between tested dual-cure resin composite luting cement (p<0,05). However, there were statistically significant difference between tested dual-cure self adhesive resin cement (p>0,05). Dynamic-aging procedure did and did not have deleterious effect on dual-cured resin composite luting cement and self adhesive resin cement, respectively. For adhesive cementation technique, composite resin luting cement is more appropriate choice.

Abstract

Objectives:The fracture strength of ceramic inlay restorations were evaluated after the use of different instrumental preparation methods.

Materials&Methods:48 extracted human molar teeth were divided into four groups, and inlay cavity preparations were performed using different instruments for each group. The groups are as follows: Group 1:Expert inlay diamond bur set was used for preparation, followed by finishing with an ultrasonic instrument (Intensiv+Sonicflex (IS)), Group 2:Only the expert inlay diamond bur set was used (Intensiv (I)), Group 3:Standart fissure diamond burs were used for preparation, followed by correction with an ultrasonic instrument (Standard+Sonicflex (SS)), Group 4:Only standard diamond burs were used for preparations (Standard (S)). The digital impressions of the inlay cavities were obtained, and the design of inlay restorations was performed using CAD program. Inlay restorations were produced from feldspathic blocks and cemented with resin cement. Afterward, the inlays were subjected to a single-load failure test using a universal testing machine. All data were analyzed statistically.

Results:The highest fracture strength mean value was observed in the IS group, with a value of 1712.17N±546.990). This was followed by the I group (1370.99N±605.877), the SS group (1207.76N±558.551), and the S group (941.73N±372.361). The lowest fracture strength was observed in the S group. The highest fracture strength was observed in the IS group. The IS group showed a statistically significant difference compared to the S group (p<0.05).

Conclusion:The group utilizing both the intensive diamond bur set and ultrasonic instruments (IS group) demonstrated the highest fracture strength compared to other groups. On the other hand, the group that used only standard diamond burs (S group) exhibited the lowest fracture strength. These results highlight the superior performance of the expert inlay preparation instruments in terms of fracture strength, emphasizing the importance of utilizing advanced instruments for optimal outcomes in inlay restorations.

Abstract

Objectives: Oral health-related quality of life (OHRQoL) is affected by different variables. Tooth loss can have negative functional, aesthetic, and psychological consequences. Dental implant treatment approach have gained increasing popularity over the years in daily practice because of dental implant’s high survival rates over time and they have become the preferred treatment option rehabilitation of edentulous patients. It is important to understand edentulous patients’ perceptions about the impacts of treatment options on their oral health-related quality of life (OHRQoL).This clinical study aimed to evaluate the maxillary or/and mandibular edentulous patient satisfaction of 2-6 implant supported fixed/removable prosthetic denture designs opposing with different prosthetic designs.

Materials and methods: A total of 36 edentulous participants received two-six implants were treated with removable or fixed prosthesis with a mean follow-up time of at least 5-8 years in the mandible or/and maxilla were selected for this study. Each group divided equally into 3 groups according to the dental prosthetic designs. Group 1: Mandibular two implants retained overdenture with locator connections and opposing maxillary total prosthesis treated group (n=13) ; group 2: Maxiller and mandibular 4-6 implant supported fixed full-arc prosthesis treated group(n=13); group 3: Mandibular 4 implants supported fixed full-arc and opposing maxillary total prosthesis treated group (n=12). Minimum 5 years from completing the prosthetic treatment, the patients recalled to the clinic and were requested to fill the OHİP 14 questionnaire and VAS scale to assess their overall quality of life and level of satisfaction, both esthetically and functionally. Measurements were performed at baseline, and at 5-8 years following implant loading. Comparison of data between groups was performed using the Kruskal Wallis tests. The level of statistical significance was considered at p < 0.05.

Results: The results of this study indicated that patient satisfaction with both fixed and removable implant supported prosthesis served succesfull results in all patients. There were no significant differences among all groups.

Conclusion: This clinical study reveals that patients with removoble or fixed implant-supported prosthesis in edentulous jaws were satisfied with their oral health-related quality of life (OHRQoL).

Abstract

Objectives: Cement retention is commonly used for implant-supported prostheses despite cementrelated issues. The aim is to compare the effects of hole structure on titanium abutments on retention
and marginal adaptation of cement-retained implant-supported prostheses when using three different materials. For this purpose, open and closed holes on abutments were used to evaluate the retention
and marginal fit of cemented Co-Cr crowns on titanium abutments.

Materials and methods: In the study, abutments with a diameter of 6 mm and Co-Cr crowns were used. The abutments were divided into two groups. In the first group, the abutments had a 10 mm teflon cap
on the screw, with both the occlusal and axial holes open. In the second group, only the occlusal opening was covered with temporary cement (cavit) on the 10 mm teflon cap.
Different adhesive agents were used for both groups: 1) Zinc phosphate cement (İnci Dental, Turkey), 2) Temporary cement (İnci Dental, Turkey), 3) Flowable composite (Dentsply Sirona, Germany). Excess
cement was standardized with 50N pressure and removed using a scalpel. The samples were evaluated for marginal adaptation using an optical microscope (Leica) at 1.25x magnification. Tensile tests were
performed using a universal testing machine (Lloyd Instruments) at a speed of 1 mm/s. The results were statistically analyzed.

Results: Temporary cement (241.546 N-219.505 N) and compomer (16.062 N- 6.928 N) showed a decrease in retention for both open and closed application of the cement escape hole, while an increase
was observed in zinc phosphate cement (282.750 N- 358.915 N). Highest retention was observed in zinc phosphate cement, while the lowest retention was observed in the compomer group.

Conclusions: Closed application of zinc phosphate cement is preferred for long-term permanent cementation, while temporary cements are suitable for interim use. Compomers are suitable for very
short-term provisional applications.

Abstract

Objectives: Activated charcoal based toothpaste has gained popularity. Although there are studies showing that this toothpaste has an abrasive effect on enamel, there is not enough information about its effects on feldspathic ceramic. The aim of this study was to determine the effect of activated charcoal toothpaste usage on the surface roughness of feldspathic ceramics.

Materials and Methods: Specimens were prepared from feldspathic ceramic blocks (Vitablocs Mark II) by cutting in a thickness of 2 mm. Surfaces of the specimens were manually polished by the same operator and initial Ra values were measured by a contact profilometer. Then, specimens were divided into three groups (N=24, n=8): Unbrushed control group (C), brushed group with activated charcoal toothpaste (AC), brushed group with only distilled water (DW). Tooth brushing simulation was applied using tooth brushing simulator (SD Mechatronic) with forward-backward motion in a linear distance of 5 mm, at speed of 25 mm/s, under 200g pressure for 10000 cycles to simulate 1 year of usage. The final roughness values of the specimens were measured after brushed. Data were statistically evaluated by paired t-test to evaluate before and after roughness changes in brushed groups and one-way ANOVA and post-hoc Tukey test to comparison all groups (α=.05).

Results: Increasing in surface roughness were statistically significant in both AC and DW group when compared before and after roughness values (p<.001 and p=0.003, respectively). There were significantly differences between unbrushed control and brushed groups. The highest roughness values were observed in group AC. Group DW was exhibited higher roughness than control group (p=.016) but lower roughness than AC group (p<.001).

Conclusion: Brushing with activated charcoal toothpaste resulted in significant changes in feldspathic ceramic surface roughness. Therefore, activated charcoal toothpastes should not be preferred in patients who had feldspathic ceramic-based restorations.

Abstract

Objective: Partial tooth loss may be restored with tooth-supported fixed prostheses or implantsupported fixed prostheses. Evaluation of bite force is crucial in assessing oral function and the
effectiveness of dental treatments. The aim of the study was to evaluate the maximum bite force (MBF) and oral health-related quality of life (OHRQoL) in patients with implant-supported fixed prostheses. In
addition, it was aimed to determine the effect of gender, age, and Body Mass Index (BMI) on the MBF.

Material and methods: Ethical approval was obtained prior to the commencement of the study. Bite force values of three different dental conditions were evaluated: the fixed implant-supported prosthesis
group (patients who had one or more posterior restored dental implants) and the control groups (dentate patients and patients using complete dentures). A total of 54 patients, with 18 individuals in
each group, were included in this study. MBF was measured with a bite force meter. The measurements were repeated 3 times (with 2-minute intervals between times) for each side, and the highest value of
the MBF was recorded for each side. OHRQoL was evaluated using the OHIP-14.

Results: The results revealed that patients with implant-supported fixed dentures exhibited higher bite force values (82 N) compared to those with complete dentures (57 N). However, these values were
lower than the bite force values observed in dentate patients (176 N). Additionally, the study found that patients with fixed implant-supported prostheses experienced an improvement in OHRQoL.

Conclusion: The findings from this pilot study suggest that implant-supported fixed dental prostheses contribute to an increase in MBF and have a positive impact on OHRQoL. These results highlight the
effectiveness of implant-supported fixed prosthesis treatment in patients with partial tooth loss.

Abstract

Objectives: To investigate the surface roughness of nano-lithium disilicate glass-ceramics, immediately after milling and following different chairside finishing procedures.

Materials and methods: One hudred and twenty flat samples (1.2mmx1mm) were produced from three different novel lithium disilicate based CAD/CAM materials (IPS e.max CAD, Amber Mill, Amber Mill
Direct) and divided into three groups (n=10/group) and treated as follows: Group 1, no polishing; Group 2, polishing with Ivoclar OptraFine; and Group 3; polishing with Ivoclar Optrafine using Amber Mill Glow
polishing paste, Group 4; Glazing. Polishing was performed using a Kavo adjustable slow speed electric contra-angle handpiece. The influence of different finishing procedures was examined by comparing
surface roughness (Ra, Rmax) data for three groups using a benchtop stylus profilometer. Statistical analysis was performed with a one-way analysis of variance (ANOVA) and Tukey’ s HSD post-hoc tests
(α=.05).

Results: The smallest surface roughness values were found for Amber Mill Direct group samples. Polishing with and without paste significantly reduced the surface roughness compared with the nonpolished control groups (1.15 μm). Group 4 exhibited the smoothest surface with 0.09 μm, followed by group 3 with 0.14 μm, and group 2 with 0.19. Using novel polishing paste significantly helped to increase the surface smoothness similar to glazing procedure.

Conclusions: Polishing after milling or occlusal adjustment is essential in order to obtain the optimal clinical performance. Chairside polishing following grinding and adjustment with discs and polishing
paste leads to comparably smooth surfaces as labside glazing procedure.

Abstract

Objective: ceramic dental prosthesis manufactured by stereolithography (SLA) are less adapted to the tooth preparation than those manufactured by subtractive technique. The objective of this study was to evaluate the influence of the variation of the length and the shaping orientation of a hollow cylinder on the deformations due to the manufacturing process of SLA.

Materials and Methods: four cylinders of 3 different lengths were manufactured by SLA. The smaller cylinder was manufactured in 2 orientations. The samples were scanned by microtomography before and after heat treatment and the root mean square (RMS) was calculated using the control software.

Results: the RMS in the lower surface increased compared to the upper surface. The RMS in the lower surface of the horizontally shaped small cylinders was lower than those vertically shaped. For the upper surface, the RMS of the small cylinders has decreased compared to the medium and large ones. These results could be explained by the proximity of the walls of the cylinder in the intrados as well as the deformations following the removal of the pillars in the extrados.

Conclusions: the variation in length and the shaping orientation influenced the deformations of the simplified models of dental prostheses.

Abstract

Objective: To investigate the potential impact of age and general bone mineral density (BMD) on the feasibility of dental implant placement in postmenopausal women with edentulous jaws.

Materials and methods: The study enrolled a total of 128 postmenopausal females with edentulous jaws, aged 52 to 91 years (mean age 70.39 ± 8.85) who sought dental implant treatment. DXA
(Lunar DXA DPX-NT) was used to measure BMD in the lumbar spine and hips and the lowest T-score from both readings was considered. Cone beam computed tomography (CBCT) was conducted using
the i-CAT system (Kavo eXam Vision) and analysed with OnDemand3D software. Multiple crosssectional images were obtained from CBCT: maxilla (central incisors, canines, first premolars, first
molars) and mandible (lateral incisors, first premolars, first molars). Bone height and width were determined on these images to determine the ability to place dental implants. To detect differences
between groups One-way ANOVA and Pearson’s chi-squared test were used.

Results: Based on the DXA results, the patients were divided into 3 groups: normal BMD (n=42, mean age 69.45 ± 9.13), osteopenia (n=56, mean age 70.09 ± 8.96), and osteoporosis (n=30, mean
age 72.27 ± 8.27) (p=0.527). No statistically significant differences were observed between the different BMD groups regarding the possibility of implant placement and general bone mineral density
and across all areas of both jaws (p > 0.05). Women with osteoporosis were able to place fewer implants on average than women with normal BMD, but the difference between groups was not
statistically significant (p > 0.05). Also, female age was not statistically significantly associated with the possibility of dental implant placement, except for the maxillary left central incisor region (p =
0.007).

Conclusions: The general BMD and age does not affect implant placement feasibility in postmenopausal women with edentulous jaws.

Abstract

Objectives
The aim of the present study is to evaluate the flexural strength of two 3d printed dental resins which haveindication for permanent restorations after receiving stress from a simulated oral condition.

Materials and methods
forty specimens of dimensions (2522mm) were printed. Twenty samples were printed by using VarseoSmileCrown plus (V) and other twenty were printed by using Crowntec (C). All samples were left
into distilled water at 371°C for thirty days in a temperature-controlled room. Then the three-point bending test was carried out using an universal test machine. The maximum loading, flexural strength at
maximum loading and modulus (E-modulus) were recorded.

Results
maximum loading at fracture (mean DS N) of each group was 22,95391 3,26307 for VarseoSmile Crown plus, 18,11244 2,27390 for Crowntec. Flexural strength at max (mean DS MPa) of VarseoSmile Crown plus
was 97,51101 15,19526, Crowntec 94,17018 11,76822. Modulus (mean DS MPa) was 3.716,80214 165.62493 for VarseoSmile Crown plus and 4.020,18442 348.51056. One-way ANOVA with Tamhane post
hoc test showed that the difference of flexural strength of two test groups was not statistically significant (P>.01).

Conclusions
Mechanical Properties of two 3d printing resins are similar and the differences are not statistically significant.Comparing flexural strength of the resins, although Crowntec recorded lower flexural strength
values, the modulus values are higher, meaning that the material is more plastic.

Abstract

Objectives: This study evaluated the satisfaction of fixed implant-supported prosthesis by using the oral health impact profile-14 (OHIP-14) and VAS scale.

Materials and methods: A total of 55 patients treated with the implant supported fixed partial denture were matched in pairs based on gender, age, subject’s medical parameters, type of incident, zone of replacement and prosthetic design. The healthy 185 implants were included in the study for according to the dental implant health scale developed and accepted by the International Congress of Oral Implantologists Consensus (ICOI). The patient-reported effect was prospectively obtained by measuring oral health impact (OHIP-14) with a a follow-up period ranging from 5 to 8 years.

Results: The majority of the dental implants were inserted anterior region (18.12%) and posterior region (81.88%). The anterior zone implants were 18.25 %. The prosthetic treatments were served as: 55.35% implant supported single crown and 44.65% implant supported fixed partial denture. The cement-retained restorations were 76.25% and screw-retained restorations were 23.75%. Mean and standard deviation, median minimum and maximum frequency and rates were put into use for descriptive statistics of data. Distribution of variables was checked using 0ne-Sample test. SPSS 22.0 programme was put into use for the analyses.

Results: The results of this study indicated that patient satisfaction with fixed implant supported prosthesis was high in all patients. It was inferred from the Ohip 14 and VAS scores analyses that fixed implantsupported prosthesis make a positive contribution to the quality of life for oral health. Improvement of the quality of life for oral health concordantly made a positive impact on the general state of health.

Conclusions: The fixed implant-supported prosthesis make a positive contribution to the quality of life for oral health.

Abstract

Objectives:
Immediate implant placement and provisionalization in extraction sockets can be beneficial for preserving soft and hard tissues around the implant. However, there is a lack of research evaluating the clinical outcomes of using Ankylos implant carriers as temporary abutments for immediately loaded implants.

The study aimed to investigate the clinical and esthetic outcomes of immediately placed and loaded
Ankylos implants in extraction sockets, using implant carriers as temporary abutments.

Materials and Methods:
Nine patients (four women, five men) aged 41-66 were included. Assessment included radiographic, clinical, and photographic analysis. Radiographic assessment involved periapical radiographs taken at different stages. Clinical assessments included plaque index, bleeding index, gingival index, and others. Photographic assessments involved photographs with a Nikon Z6 camera. Data analysis was performed using GraphPad Prism V.9.1 for macOS.

Results:
After 3 months, mid-facial peri-implant mucosal level showed a mean soft tissue loss of 1.18 ± 0.42 mm. Marginal bone level displayed a mean value loss of 0.53 ± 0.33 mm. Pink Esthetic Score scores averaged 7.9 ± 1.45. No major complications such as implant loss or inflammation were encountered. All implants remained stable and were loaded for 3-4 months before permanent crown restoration.

Conclusion:
The use of Ankylos implant carriers as temporary abutments for immediately loaded implants in extraction sockets can be an effective option, with minimal soft and hard tissue loss. The PES scores are comparable to other studies.

Clinical Implications:
This study suggests that immediate implant placement with Ankylos implant carriers as temporary abutments may be a viable option for preserving tissues and achieving satisfactory esthetic outcomes. Dental professionals should consider this as an alternative treatment option. Further research with larger sample sizes is needed for a more comprehensive understanding.

Abstract

Objectives: Evaluate the accuracy of holographic image projections onto a dental model using different trackers.

Materials and methods: An application has been developed for the ‘‘HoloLens 2,, device that allows users to see holograms in a specific location in real time. To improve precision, an ,,L’’- shaped tracker with contrasting stickers was produced and compared to the ,,Navident’’ dynamic navigation tracker. For calibration purposes, a pen with a cube containing contrasting stickers was created. A study was conducted to assess the accuracy of hologram projection during calibration.

Results: The average angle between the positions of the marked points during calibration and the fixed points’ positions in the hologram value using the “Navident” tracker is 5.06 degrees higher than using the “L” shaped tracker. All distances between the points are statistically significant (p<0.05). The average values of pen oscillation were evaluated in four-point positions during the calibration: the most accurate point average (0.57 mm) was achieved using the “L” shaped tracker, while the fourth point achieved the highest point precision average (2.15 mm) using the “Navident” tracker.

Conclusion: A holographic image is more stable when using a tracker that is angled and covered with a distinctive, non-repeating geometric pattern in contrasting colours. Calibration is an important procedure for the accuracy of the holographic image’s position on the real object.

Abstract

The aim of the present study was to compare microleakage of enamel and dentin margins of cervical restorations after restoring different types of composite-resin restorative materials. Cervical cavities were prepared in both buccal and lingual surfaces of fifteen extracted sound human molar teeth using with cyclindrical-shaped diamond burs under a continuous water flow. Cavity margins of enamel and dentin were located in 2mm above and below the cementum-enamel junction (CEJ), respectively. After cavity preparation two-step universal adhesive (G2-BOND Universal, GC) were applied to enamel by selective enamel etch mode and to dentin by self etch mode. Adhesive agent polymerized for 10-seconds by using high-power light emitting diode light curing unit (LED-LCU) (D-Light Pro, GC). Depending on the restoration of cavities (n=10/group) Group1: restored with shortfibre reinforced flowable composite indicated for dentin replacement in direct restorations (everX Flow, GC); Group2: restored with flowable composite (G-ænial Universal Flo, GC); Group3: 2/3 of cavity and 1/3 cavity restored with short-fibre reinforced and flowable composite. Polymerization of restorative materials were achieved using high-power LED-LCU for 40-seconds light irradition time. After finishing and polishing procedures restored test specimens were stored for 24-hour in water at 37oC and then thermocycled by 5oC-55oC for 10000 cycle (Thermocycler, The-1100, SD-Mechatronik, Germany). Microleakage measuremets were achieved conventional dye penetration method for assessing microleakage in enamel and dentin margins surrounding the restorations. One-way ANOVA showed that the mean microleakage of all tested groups showed significant differences (p<0.05) within both enamel and dentin margins. Group3, restoration with short-fibre reinforced and flowable composite revealed no and least leakage at enamel and dentin margin, respectively. Within the limitations of this in vitro study, it can be concluded that, in clinical situation, if the cavity margin is placed below CEJ, it is advisable to use short-fibre reinforced flowable composite as a base material.
