Objective: To explore the relationship between parenting styles and children's personality traits and parental-reported sleep bruxism (SB).

Methods: A total of 301 parents/caregivers of Brazilian children participated in this cross-sectional study and answered an online questionnaire addressing sociodemographic characteristics, sleep-related behaviors and parent-reported SB. The Brazilian versions of the Parenting Styles and Dimensions Questionnaire and the Eysenck Personality Questionnaire-Junior assessed children's parenting styles and personality traits. Descriptive analysis and multinomial logistic regression were used.

Results: Boys (OR=2.07; 95% CI=1.09-3.91) whose snoring (OR=2.98; 95% CI=1.55-5.73) were associated with mild parent-reported SB. Boys (OR=2.61; 95% CI=1.20-5.70) and high levels of neuroticism (OR=2.27; 95% CI=1.06-4.860) were associated with moderate/severe parent-reported SB. Authoritarian parenting attitudes decreased the likelihood of moderate/severe parent-reported SB (OR=0.37; 95% CI=0.16-0.86).

Conclusions: Parents/caregivers who exhibited more authoritarian attitudes reported a lower prevalence of moderate/severe children SB. Neuroticism trait and snoring influenced the severity of parent-reported SB.

Objective: To investigate the relationship between sleep bruxism(SB) and gastroesophageal reflux disease (GERD) with the use of validated questionnaires in a general population convenience sample.

Methods: SB behaviour was evaluated in accordance with the Subject-Based Assessment strategy recommended in the Standardized Tool for the Assessment of Bruxism (STAB). .To evaluate GERD-related symptoms, the GERD-Q questionnaire was adopted. To study the correlation between current SB and GERD, Spearman test was performed. Mann-Whitney-U test was adopted to compare GERD-related symptoms in two distinct group comparisons based on the presence of current SB and a history of SB, respectively.

Results: A significant but weak positive correlation between current SB and GERD was found (r = .112; p = .044). No significant differences in GERD-related symptoms between groups emerged.

Conclusions: This investigation showed a positive but weak correlation between current SB and GERD-related symptoms. Larger scale studies in representative samples are needed to further explore this correlation.

Objective: To evaluate the prevalence of temporomandibular disorders (TMD) and their association with sociodemographic and psychosocial factors among 33- to 35-year-old Finnish adults in the Northern Finland Birth Cohort 1986 (NFBC1986).

Methods: The sample included 1788 NFBC1986 subjects that have been clinically examined in 2018-19. TMD symptoms were inquired, and clinical TMD examinations were performed based on the Diagnostic Criteria of TMD (DC/TMD). Sociodemographic factors and depression/anxiety symptoms based on Hopkins Symptoms Checklist-25 (HSCL-25) and Generalized Anxiety Disorder-7 (GAD-7) were inquired using questionnaire.

Results: The prevalence of at least one of TMD symptoms was 30.4%. Women had higher prevalence of TMD symptoms and diagnoses compared to men. Female sex, anxiety/depression symptoms and socioeconomic group associated significantly with TMD pain symptoms and pain-related diagnoses.

Conclusion: The most frequent TMD diagnosis was myalgia and 26.4% had at least one TMD diagnosis. Anxiety/depression symptoms were associated with TMD symptoms and pain-related diagnoses.

Objective: To evaluate the prevalence of serum vitamin D and B12, calcium, phosphorus, magnesium levels, and rheumatoid factor (RF) status in patients with bilateral temporomandibular joint osteoarthritis (TMJ-OA) and their correlations with clinical and radiological findings.

Methods: The clinical and radiologic findings and serum vitamin and mineral levels of 90 patients diagnosed with bilateral TMJ-OA were recorded. Descriptive statistics and the Spearman's Rho correlation test were performed.

Results: Low serum vitamin D and B12 levels were detected in 82 (91.1%) and 74 (82.2%) patients. Calcium and phosphorus levels were seen at low rates. RF status was recorded as unfavorable in all patients. Correlations were found between age and the serum vitamin and mineral levels, except phosphorus. Low serum vitamin D levels correlated with pain complaints at rest and painless MIO. Serum B12 levels correlated with condylar erosion. Serum magnesium levels correlated with painful MIO and condylar osteophyte.

Conclusion: Patients with bilateral TMJ-OA showed a high prevalence of low serum vitamin D and B12 levels.

Objective: To evaluate the effect of conservative therapeutic interventions in adult patients with temporomandibular disorders (TMD) and associated otologic symptoms.

Methods: An electronic search across six databases and grey literature was conducted. Studies were assessed for risk of bias, a random-effects meta-analysis, and the certainty of the evidence was evaluated using the GRADE tool.

Results: Eighteen studies were included in the final synthesis. Otologic symptoms significantly decreased following intervention compared to baseline [OR = 0.09; 95% CI = 0.04 - 0.23, I² = 56%], reflecting an approximately 11-fold reduction in symptom likelihood of otologic symptoms after conservative treatment. Of the studies, eight had a low risk of bias, five had moderate, and four had high risk, with evidence certainty rated as very low.

Conclusion: Conservative therapeutic interventions for TMD appear to reduce otologic symptoms. However, the certainty of the current evidence is limited, warranting further research to establish more definitive conclusions..

Objective: We examined the relationships between the structural connectome and temporomandibular disorders (TMDs).

Methods: Bidirectional Mendelian randomization analyses were conducted using Genome-wide association studies data on the structural connectome and TMDs.

Results: Positive associations with TMD risk were found for white matter structural connectivity from the left hemisphere limbic network to putamen, left hemisphere salience_ventral attention network to caudate, right hemisphere visual network to thalamus, and right hemisphere salience_ventral attention network to right hemisphere control network, while negative associations were observed for connectivity from the left hemisphere control and somatomotor networks to pallidum, left hemisphere somatomotor network to right hemisphere dorsal attention network, and right hemisphere somatomotor network to hippocampus (p< 0.05). In TMD patients, connectivity from the Left-hemisphere visual network to putamen was reduced, whereas connectivity from the Left-hemisphere limbic network to left-hemisphere control network was increased (p< 0.05).

Conclusion: Our findings provide insights into the TMD pathogenesis.

Objective: The study aimed to determine the associations between several important and potentially modifiable health variables and TMD signs and symptoms.

Methods: A total of 209 adult dental patients from two clinics completed surveys on demographics, self-reported awake and sleep bruxism, TMD signs and symptoms, stress, depression, chronic pain, and sleep quality. Correlations and regression analyses were used to identify associations between these health variables and TMD symptoms.

Results: Awake bruxism was significantly associated with chronic pain intensity, jaw pain, clenching pain, and headaches. Stress and depression correlated with chronic pain intensity and clenching pain. No correlation was found between BMI and TMD symptoms. In multivariate analysis, both awake and sleep bruxism were associated with TMD symptoms, while sleep quality was related to pain on chewing and depression was associated with chronic pain intensity.

Conclusions: Identifying these associations can guide clinicians in assessing, educating and managing TMD-related issues by addressing bruxism, sleep quality, and depressive symptoms.

Objective: Less than ideal contacts have been reported following aligner therapy, but it is considered a transitory problem, spontaneously resolving with the phenomenon of settling. Methods: Thirty-nine orthodontic patients (14 treated with aligners; 25 with fixed appliances) were evaluated with a digital occlusal analysis system (T-scan™10), assessing Maximum Intercuspation contact simultaneity, symmetry, and relative force distribution at treatment completion and after 3 and 6 months.

Results: No significant differences in occlusal contact quality were found between groups at treatment completion or follow-up. The center of force moved posteriorly and remained stable after 3 months but was located more anteriorly in females (p = 0.01). One-third of patients (both groups combined) had marked contact force asymmetry even after 6 months' retention. Conclusion: Occlusal contacts were comparable at completion of treatment with aligners or brackets and after 3-6 months of retention. Settling did not improve marked asymmetry in all patients.
