Objective: The study aimed to investigate the association of sleep bruxism (SB) and awake bruxism (AB) with health-related factors.

Methods: Data on bruxism and diagnosed diseases, use of psychoactive substances and regular identified psychoactive drugs were collected from 1,962 subjects in the Northern Finland Birth Cohort 1966 through a questionnaire. The associations were analyzed using chi-square tests and binary regression models, adjusting for gender and education, and for anxiety/depression symptoms.

Results: Migraine and gastric/duodenal disorders, use of serotonergic antidepressants and a high number of psychoactive drugs associated significantly with AB and SB. Gastrointestinal diseases associated with SB. Poor general health and hand eczema associated with AB. Based on the multivariate model, depression/anxiety symptoms seemed to mediate the associations of bruxism with depression, hand eczema, self-reported gastric/duodenal disorders and the number of identified drugs.

Conclusion: Several diseases, depression/anxiety symptoms and psychoactive medications were associated with SB and AB, the associations being stronger with AB than SB.

Objectives: In recent years, a smartphone-based ecological momentary assessment (EMA) approach for assessing awake bruxism (AB) has attracted growing interest, both in clinical and research settings. The present study was designed to investigate subjects' experience using an EMA-based smartphone application to detect factors that could hamper or facilitate its use for clinical and research purposes.

Unlabelled: The prevalence of temporomandibular disorder (TMD) in patients with (dentofacial deformities) DFD is high, indicating a multifaceted relationship between physical and psychosocial factors.

Objective: To identify clusters of patients with DFD based on variables related to TMD, psychological aspects, somatization, oral habits, and sleep.

Method: Ninety-two patients with DFD were evaluated before orthognathic surgery according to demographic data, facial profile, presence of painful TMD (DC/TMD), psychological aspects, oral habits, comorbidities, substance use, and sleep quality.

Article Synopsis
  • The study investigates the link between non-physiological oral behaviors and awake bruxism (teeth grinding) in adolescents, focusing on their association with mental health issues like depression and anxiety.
  • Out of 100 adolescents studied in Medellín, Colombia, 79 completed assessments to measure these behaviors and mental health symptoms using specific questionnaires.
  • Findings reveal that while depression isn't a key predictor of non-physiological oral behaviors, anxiety significantly increases the likelihood of both NPAOB and awake bruxism among adolescents.

The aim of this study was to verify the correlation of self-reported sleep and awake bruxism with demographic characteristics, oral behaviors, anxiety, temporomandibular disorder (TMD) signs and symptoms, sleep quality, and orthodontic treatment history in dental students. A total of 104 students of Dentistry located in Paraná (South Brazilian State) answered the following self-administered questionnaires: Oral Behavior Checklist, State Anxiety Inventory, TMD signs and symptoms questionnaire, and the Pittsburgh Sleep Quality Index. Associations between possible awake bruxism (AB) and sleep bruxism (SB) with sleep quality, anxiety, and TMD were analyzed by Poisson Regression with robust variance.

: Bruxism is a masticatory muscle activity, phasic or tonic, with/without teeth contact, that appears in sleep or an awake state. An instrumental technique used to measure the surface electromyographic (sEMG) activity of the masseter muscle is used to diagnose bruxism activity during sleep and while awake. The objective of this study was to compare the variation in bruxism (sleep and awake) indices and masseter activity indices in low sleep bruxism and moderate sleep bruxism before and after wearing an occlusal appliance (OA) for 3 months each night.
