“…Already for a longer time, bruxism has been considered a relief factor for psychological stress and even as an expression of aggression. 90,91 Nowadays, other potential positive health outcomes of bruxism have been suggested in the literature, such as prevention or restoration of upper airway collapse in obstructive sleep apnoea, 13 neutralising pH drops in gastro-oesophageal reflux patients by increasing salivary flow rate, 92 reducing oral dryness by mechanically stimulating salivary flow rate via masticatory muscle activityinduced parotid gland massage, 93 improving mineral bone density by traction of the jaw muscles on their bony origins and insertions within the masticatory system, 94 and even preventing of slowing down cognitive decline by improving the perfusion of blood in the brain due to chewing-like masticatory muscle activities. 95 Since it is important to allow these potential positive consequences of bruxism to occur, the presence of the mentioned conditions should also be assessed as part of a comprehensive bruxism assessment.…”

This paper summarises the background reasoning and work that led to the selection of the items included in the Standardised Tool for the Assessment of Bruxism (STAB), also introducing the list of items. The instrument is currently being tested for face validity and on‐field comprehension. The underlying premise is that the different motor activities included in the bruxism spectrum (e.g. clenching vs. grinding, with or without teeth contact) potentially need to be discriminated from each other, based on their purportedly different aetiology, comorbidities and potential consequences. Focus should be on a valid impression of the activities' frequency, intensity and duration. The methods that can be used for the above purposes can be grouped into strategies that collect information from the patient's history (subject‐based), from the clinical assessment performed by an examiner (clinically based) or from the use of instruments to measure certain outcomes (instrumentally based). The three strategies can apply to all aspects of bruxism (i.e. status, comorbid conditions, aetiology and consequences). The STAB will help gathering information on many aspects, factors and conditions that are currently poorly investigated in the field of bruxism. To this purpose, it is divided into two axes. Axis A includes the self‐reported information on bruxism status and potential consequences (subject‐based report) together with the clinical (examiner report) and instrumental assessment (technology report). Axis B includes the self‐reported information (subject‐based report) on factors and conditions that may have an etiological or comorbid role for bruxism. This comprehensive multidimensional assessment system will allow building predictive model for clinical and research purposes.

“…Furthermore, osseous changes at the mandibular angle region and in the TMJs have been reported in the literature, particularly among patients with dental parafunctions. Studies have documented changes of the mandibular bone in the jaw angle region in patients with bruxims [7][8][9][10][11][12]. Similarly, patients with temporomandibular joint osteoarthritis present progressive cartilage breakdown and degenerative osseous alterations in the TMJs [13][14][15].…”

Background The purpose of this study was to determine the prevalence of radiographic changes in the mandibular angle (bone apposition) and osseous alterations in the temporomandibular joints (TMJs) in the adult population of Switzerland. In addition, the study intended to investigate possible correlations between the two sites of contour bone changes (mandibular angle and TMJ) and to analyze various patient-related factors, including sex, age, dental status, and medical history. Methods Panoramic radiographs of 600 patients distributed into six age groups (283 females, 317 males, aged 20 to 79 years) were included to evaluate radiographic changes. The bone in the mandibular angle region and the shape of the condylar heads were examined for contour changes (bone apposition at the jaw angles and osseous changes of the TMJs). General estimating equations, binormal tests, and chi-squared tests were used for statistical analysis. Results Approximately half of the mandibular angles (47.8%) showed bone apposition, mostly bilateral. TMJ alterations were less common (27%), often unilateral, with flattening being the most frequent finding. No significant correlation was found between the two sites. Bone apposition at the mandibular angle showed a significant male predominance, whereas TMJ changes did not differ by sex. Alterations in both sites increased with age, and were not related to dental status or analgesic use. Conclusions Bone apposition at the mandibular angle should be interpreted as part of the natural functional adaptation of the bone associated with aging. Assuming that parafunctional habits may influence the development and progression of alterations in the mandibular angle or TMJs, the presence of radiographic changes in these areas should prompt dental clinicians to investigate further in this direction. Trial registration The study was approved by the Swiss Association of Research Ethics Committees (swissethics), BASEC reference number: 2020–00963 (25.05.2020).

“…The HU value, which is frequently used in the evaluation of mineral density in computer tomography (CT) and cone-beam computed tomography (CBCT) images, has not been widely used in DPRs. Radiographic evaluation of bone mineral density and bone height is important in dental treatment planning in patients with bruxism (6). The aim of this study is to evaluate the changes in the jaw bones of bruxers exposed to long-term, strong bite forces using radiomorphometric indices and HU.…”

Background: The aim of this retrospective study is to evaluate the effects of bruxism on the mandibular bone using radiomorphometric indices and Hounsfield unit (HU) value on digital panoramic radiography (DPR). Materials and Methods: Panoramic radiographs of 120 patients, 60 with bruxer and 60 without (control), were analyzed. Mental index (MI), panoramic mandibular index (PMI), antegonial index (AI), gonial index (GI), antegonial notch depth (AND) and mandibular cortical index (MCI) were measured bilaterally in DPR. Gray values of the cancellous bone and cortical bone at predetermined landmarks in the mandible were measured using the HU value on the DPR. Results: MI was found to be higher and statistically significant in bruxers compared to the control group (p<0.05). There was no statistically significant difference between the bruxism group and the control group in terms of AI, GI and MCI (p>0.05). While there was a significant difference in HU value in the cancellous bone in the bruxism group and the control group (p<0.05), there was no statistically significant difference in HU values between the two groups in the cortical bone (p>0.05). Conclusions: MI and AND measurements can be used in the diagnosis or follow-up of bruxism. There is no diffe-rence in mandibular cortical bone height in patients with and without bruxism according to AI, GI, and MCI. The mean PMI value measured on the left side differs between the groups. In bruxism patients, increased density in the mandibular cancellous bone, is greater and significantly different from the increase in cortical bone.
