The definition of bruxism has evolved over the past few years, progressively going beyond the old belief that bruxism is synonymous of grinding the teeth while asleep (Lobbezoo et al., 2013; Lobbezoo et al., 2018). With the increase in knowledge concerning the sleep correlates and the muscle activities that may equally be present also during wakefulness(Manfredini et al., 2019; Manfredini et al., 2021), the bruxism construct has shifted from a pathology or disorder to a motor activity that may be a sign of underlying conditions and may even have possible physiological or protective relevance (Raphael et al., 2016; Manfredini et al., 2016).

In the 2018 consensus paper, sleep bruxism (SB) is defined as a masticatory muscle activity (MMA) during sleep that is characterized as rhythmic (phasic) or non-rhythmic (tonic) and is not a movement disorder or a sleep disorder in otherwise healthy individuals. Awake bruxism (AB) is defined as a masticatory muscle activity during wakefulness that is characterized by repetitive or sustained tooth contact and/or by bracing or trusting of the mandible and is not a movement disorder in otherwise healthy individuals (Lobbezoo et al., 2018).

Within these premises, while preparing the Standardized Tool for the Assessment of Bruxism (STAB), the need emerged for the identification of the best strategy to define the bruxism status, comorbidities, etiology, and consequences. As muscle activities, both sleep and awake bruxism require a thorough assessment that could be based on a combination of subject-based, clinically based, and instrumentally based information.

The rationale for creating the tool and the road map that led to the selection of items included in the STAB have been discussed in some recent publications (Manfredini et al., 2020; Manfredini et al., 2022). This course will present the road map to STAB, the rationale for its background, and the instrument itself, with the list of items included in each specific axis and domain.

Daniele Manfredini
Daniele Manfredini

Daniele Manfredini received his DDS from the University of Pisa, Italy in 1999, a MSc in Occlusion and Cran- iomandibular Disorders in 2001 from the same University, a PhD in Dentistry from the ACTA Amsterdam, The Netherlands, in 2011, and a Post-Graduation Specialty in Orthodontics from the University of Ferrara, Italy, in 2017. He achieved the Diplomate Status from the American Academy of Orofacial Pain in 2021.

He was a clinical fellow at the Section of Prosthetic Dentistry, Department of Neuroscience, University of Pisa, Italy until 2005. From 2006 to 2016, Daniele Manfredini has been Assistant Professor at the School of Dentistry and coordinator of the research projects at the TMD Clinic, Department of Maxillofacial Surgery, University of Padova, Italy.

Since 2017, Daniele Manfredini has held teachings in Oral Physiology and in Clinical Gnathology at the School of Dentistry, University of Siena, Italy.

On January 2017, the Italian Ministry of University and Research (MIUR) appointed him as a Full Professor at the age of 41.

Daniele Manfredini authored more than 230 papers in the field of bruxism and temporomandibular disor- ders in journals indexed in the Medline database (Scopus H-index=49). He also edited, among the others, the book “Current concepts on temporomandibular disorders” (Quintessence Publishing, 2010), including contributions from 45 world-renowned experts, and co-authored several textbooks on the same topics.

Based on publication ratings, in November 2013, the US agency Expertscape ranked Daniele Manfredini as world #1 expert in the field of temporomandibular joint disorders, and, in November 2018, also as #1 in the field of bruxism. From then on, Daniele Manfredini has always been classified within the top three experts in both conditions. Since 2018, Daniele Manfredini is Member and Coordinator of the Bruxism Consensus Panel within the International Association for Dental Research, which works on the updated definition and classification strategies for bruxism.
