Objective: This study investigated the relationship between sleeping time and temporomandibular disorders (TMDs).Methods: This study used data from the Fifth Korea National Health and Nutrition Examination Survey from 2010 to 2011. The final sample size consisted of 11,782 adults aged ≥19 years. Logistic regression analysis was performed to assess the relationship between sleeping time and TMD.Results: The adjusted odds ratios of the TMD group were 1.421 (1.067, 1.892) (Model 1), 1.388 (1.028, 1.873) (Model 2), and 1.360 (1.012, 1.826) (Model 3) for subjects with sleeping time ≤5 hours (p < 0.05) and 1.317 (0.992, 1.748) (Model 1), 1.358 (1.01, 1.827) (Model 2), and 1.352 (0.977, 1.872) (Model 3) for subjects with sleeping time ≥9 hours (p < 0.05).Conclusion: Sleeping time ≤5 hours and ≥9 hours were associated with an increased rate of TMD.

Background: The prescription rate for antibiotics in dental clinics is not declining despite the increase in the antibiotic resistance problem. In this study, we observed the change in antibiotic prescription rates by dentists in a Korean dental hospital for various treatments after conducting interventions targeting dentists.Methods: The first intervention was to distribute guidelines. The second intervention was to remove the bundled prescription button containing antibiotics from the Electronic Medical Record system. A total of 22,098 treatment records were divided into 12 main treatment categories, and Chi-square tests and logistic regression analyses were performed.Results: After the interventions were applied, the overall prescription rate for antibiotics dropped. The antibiotic prescription rate decreased by an odds ratio of 0.774 (95% CI: 0.686-0.873) after intervention 1 and by an odds ratio of 0.574 (95% CI: 0.501-0.658) after intervention 2. The treatments with significantly reduced antibiotic prescription rates were extraction for orthodontic treatment, dental implant surgery, extraction of an impacted tooth and general extraction. These treatments are typically performed in patients without an active infection. The prescription rate did not change for periodontal treatments or endodontic treatments, which are usually performed in patients with an infection. The prescription rate also remained constant for minor operations and other basic treatments.Conclusion: The interventions induced behavioural changes in the dentists and were effective in lowering the antibiotic prescription rates in a dental hospital. In particular, there was a significant reduction in the prescription rates for implant surgery and tooth extraction in the absence of infection. [ABSTRACT FROM AUTHOR]
