Objective: To Determine whether possible sleep bruxism (PSB) is associated with daytime oral habits and sleep behavior in schoolchildren. Methods: A cross-sectional study was conducted with a representative sample of 8-to-10-year-old children (n = 544). The Sleep Behavior Questionnaire (SBQ) was administered to evaluate sleep behavior. Daytime oral habits were evaluated using the Nordic Orofacial Test-Screening. Results: The prevalence of PSB was 21% and was significantly higher in children with reports of awake bruxism (p < .001; PR = 2.76; 95% CI: 2.01–3.79), snoring (p < .001; PR = 1.93; 95% CI: 1.41–2.65), and sucking/biting the lips daily (p = .034; PR = 1.73; 95% CI: 1.08–2.78). No socioeconomic characteristics were associated with PSB in the final model. Conclusion: Possible sleep bruxism in schoolchildren is associated with possible awake bruxism, snoring, sleep fragmentation, and daytime sleepiness

The aim was to determine whether there is a difference in the periodontal aspect (gingival recession, probing pocket depth) of the palatally displaced canine (PDC) compared to the contralateral canine. Also, from a surgical perspective, sought to determine whether there is a difference (surgical duration, postoperative pain) between the surgical techniques. The word combinations were adapted for each electronic database: PubMed, LILACS, Scopus, Web of Science, Cochrane Library and gray literature. Studies that met the following criteria were considered eligible: (P) Patients who received orthodontic-surgical treatment for correction of PDC; (I) Performing orthodontic-surgical treatment for traction of the PDC; (C) Comparison of the tractioned canine with its contralateral or between the two techniques; (O) Gingival recession, probing pocket depth, postoperative complications and surgical duration; (S) Randomized and nonrandomized clinical studies or observational studies. The overall prevalence of gingival recession was estimated to be 10.53% [95% CI, 3.87% - 25.59%; I2 = 88%]. No statistically significant difference (p > 0.05) was found between the means of the variables gingival recession, probing pocket depth and surgical duration. The evidence suggests that traction of palatally displaced canines can be considered a reliable and acceptable procedure.

Objective: to verify the relationship between otological symptoms and parafunctional habits in individuals with temporomandibular joint dysfunction. Methods: evaluations were based on the clinical records of 768 patients treated at a temporomandibular joint diagnostic center from 2010 to 2016. The inclusion criteria were completely filled out charts of adult patients (> 18 years of age) and the final sample comprised 516 clinical records. The presence/absence of parafunctional habits and otological symptoms (tinnitus, hearing impairment, dizziness, the sensation of plugged ears and imbalance) was recorded. Results: statistically significant associations were found between otological symptoms and both sex and the presence of parafunctional habits, as otological symptoms were more prevalent among women and individuals with at least one parafunctional habit. Conclusion: in the present sample, otological symptoms were positively associated with parafunctional habits in individuals with temporomandibular joint dysfunction.
