Background: Awake Bruxism (AB) management includes cognitive and behavioural changes. Digital and analogic tools can be used to remind the individual to control/avoid AB behaviours. However, no study addressed both tools together. Objective: To compare the efficacy of the combination of digital (smartphone application) and analogic (adhesive reminders) tools versus digital tool alone for AB management. Methods: Seventy‐two individuals diagnosed with probable AB were divided into 3 groups: Group 1 (n = 24), used both digital and analogic tools during 30 days; Group 2 (n = 24), used only a digital tool during 30 days and Group 3 (n = 24), used only a digital tool for the first 15 days and then added the analogic tool for 15 days. The AB frequency was measured in real‐time with a smartphone app, which sent alerts asking the individuals if they were doing any AB behaviours (bracing, teeth contact, clenching or grinding). Groups were compared using one‐way ANOVA and before‐after adding an analogic tool (group 3) by paired t‐test, considering α = 0.05. Results: All groups showed a decrease in AB behaviours at the end of the evaluation period. Group 1 (digital and analogic tools) showed the lowest average of AB behaviours among all groups; however, statistically significant differences were found only for the comparison between groups 1 and 2. In group 3, a significantly greater reduction in AB behaviours was found after combining both approaches. Conclusion: The combination of digital and analogic tools showed the greatest reduction of AB frequency and can be recommended for AB control. [ABSTRACT FROM AUTHOR]

The literature on Temporomandibular Disorders (TMD) incidence commonly reports sociodemographic factors such as gender and age. However, the role and prevalence of other sociodemographic factors in TMD are not well defined. Therefore, this scoping review aimed to report the prevalence of sociodemographic factors in TMD patients. A systematic search was conducted in the PubMed and Web of Science databases to identify clinical trials in adult populations, using the Research Diagnostic Criteria for TMD (RDC/TMD) or the Diagnostic Criteria for TMD (DC/TMD) and reporting sociodemographic data in TMD patients. Twenty-seven studies meeting the criteria were included in this review. The most commonly reported sociodemographic factors assessed in the included studies were age, race, education, job, income, and marital status. TMD prevalence was observed to be higher among younger and divorced individuals among the included studies. However, conflicting results were found for education level, and employment was not considered a risk factor for TMD. Although this review has methodological limitations, it suggests an association between TMD incidence and certain sociodemographic factors; nevertheless, further studies are needed to establish this relationship more conclusively.

Purpose: To compare maximum bite force, masseter thickness, and oral health-related quality of life (OHRQoL) in elderly patients rehabilitated with conventional complete dentures (CDs) and single-implant overdentures (SIOs).Materials and Methods: A paired design was conducted, and 12 elderly patients were selected. Initially, a set of new CDs was manufactured and placed. After a 2-month adaptation period, the mandibular CD was transformed into an SIO by inserting one osseointegrated implant into the symphysis region. All variables were evaluated 2 months after both treatments (CD and SIO). Maximum bite force was evaluated using pressure sensors, while masseter thickness was obtained via ultrasound during muscle contraction and relaxation. The Oral Health Impact Profile for edentulous people (OHIP-Edent) was used to measure OHRQoL. Data were analyzed using Student t test and Wilcoxon test. Pearson coefficient of correlation between bite force and masseter thickness was calculated.Results: Values for maximum bite force and masseter thickness during contraction increased significantly after SIO use (P < .001), indicating an improvement in muscle function. Considering OHRQoL, the general score and the domains functional limitation and physical pain were reduced (P < .05), indicating better perception of OHRQoL, with SIO use. Moreover, masseter thickness during contraction was moderately correlated with bite force (r = 0.480; P = .018).Conclusion: Using SIO increased the maximum bite force and masseter thickness of elderly patients, leading to an improved OHRQoL.

To assess the frequency of reported masticatory muscles activity during wakefulness (i.e., awake bruxism [AB]), levels of anxiety, depression, stress, and the oral health-related quality of life (OHRQoL) in college preparatory students. Sixty-nine college preparatory students participated in the study. AB was evaluated by the Oral Behaviors Checklist (OBC) and a smartphone-based ecological momentary assessment (EMA; [Bruxapp®]). Anxiety and depression were measured by the Hospital Anxiety and Depression Scale, stress was evaluated by the Perceived Stress Scale, and OHRQoL was obtained by The Oral Health Impact Profile-14. Data were analyzed by Pearson's correlation coefficient (α = 0.05). The average EMA-reported frequency of AB behaviors was 38.4%. Significant correlations were found between AB and the OBC, anxiety, depression, stress, and OHRQoL (p < 0.001). College preparatory students demonstrated moderate frequency of AB, which was significantly correlated with psychosocial factors. [ABSTRACT FROM AUTHOR]

Background: The recent introduction of ecological momentary assessment (EMA) smartphone-based strategies has allowed achieving some interesting data on the frequency of different awake bruxism (AB) behaviors reported by an individual in the natural environment. Objective: The present paper aims to review the literature on the reported frequency of AB based on data gathered via smartphone EMA technology. Methods: On September 2022, a systematic search in the Pubmed, Scopus and Google Scholar databases was performed to identify all peer-reviewed English-language studies assessing awake bruxism behaviors using a smartphone-based Ecological Momentary Assessment. The selected articles were assessed independently by two authors according to a structured reading of the articles' format (PICO). Results: A literature search, for which the search terms "Awake Bruxism" and "Ecological Momentary Assessment" were used, identified 15 articles. Of them, eight fulfilled the inclusion criteria. The results of seven studies using the same smartphone-based app reported a frequency of AB behaviors in the range between 28.3 and 40% over one week, while another investigation adopted a different smartphone-based EMA approach via WhatsApp using a web-based survey program and reported an AB frequency of 58.6%. Most included studies were based on convenience samples with limited age range, highlighting the need for more studies on other population samples. Conclusions: Despite the methodological limits, the results of the reviewed studies provide a standpoint for comparison for future studies on the epidemiology of awake bruxism behaviors.

Objective: To compare the mastication and oral sensory function of individuals with and without sleep bruxism. Methods: The sample comprised 60 volunteers, of which 30 were bruxers (mean age = 30.5 ± 6.0) and 30 non-bruxers (mean age = 28.6 ± 3.3). Sleep bruxism was clinically diagnosed and confirmed using the Bruxoff® device. Mastication was evaluated according to swallowing threshold and masticatory efficiency. Swallowing threshold was determined from the median particle size of Optosil®, obtained after an individualized number of masticatory cycles, which was first determined by chewing peanuts; masticatory efficiency was estimated by the sieving method. Oral stereognosis test was used to determine the oral sensory function. Variables were compared using one-way ANOVA (p < .05). Results: The median particle size, masticatory efficiency, and oral sensory function did not differ significantly between bruxers and non-bruxers (p > .05). Conclusion: Dentate adults present similar mastication and oral sensory function, despite the presence of sleep bruxism. [ABSTRACT FROM AUTHOR]

Objective: To evaluate the prevalence of temporomandibular disorder (TMD) in dental students and its correlation with anxiety.Methods: After probability sampling, 105 students were selected. The diagnosis of TMD was carried out using the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) - Axis I; the anxiety level was obtained by the State-Trait Anxiety Inventory (STAI). Data from TMD and anxiety were calculated through frequency and Chi-square test to assess the association between TMD and anxiety, considering a significance level of 5%.Results: TMD was present in 36.2% of the students; disc displacement (42.1%), and arthralgia (42.1%) were the most prevalent subtypes. The majority of students presented both traits (57.1%) and state (65.7%) anxiety in mild levels, followed by moderate levels. No statistical association between TMD and anxiety was found (p > 0.05).Conclusion: Joint TMD was the most prevalent subtype of TMD in dental students and was not associated with anxiety levels.

Objective: To evaluate the relationship between temporomandibular disorders (TMD) and craniocervical posture in the sagittal plane measured from lateral radiographs of the head.Methods: The sample was comprised of 80 randomly selected students of dentistry at the Federal University of Rio Grande do Norte. Research Diagnostic Criteria for TMD (RDC/TMD) was used to evaluate the signs and symptoms of TMD. Lateral radiographs of each individual were used to measure the position of the hyoid bone, the craniocervical angle, and the occiput-atlas distance. A chi-square test was used to evaluate the relationships between craniocervical posture measures and TMD.Results: No relationship was found between TMD and the craniocervical posture measured by the positioning of the hyoid bone, head rotation, and the extension/flexion of the head (p > 0.05).Conclusion: It can be concluded, therefore, that no relationship exists between cervical posture in the sagittal plane and TMD.
