Investigating the Association between Obstructive Sleep Apnea and Temporomandibular Joint Disorders: A Case-Control Study

This study aims to explore the connection between obstructive sleep apnea (OSA) and temporomandibular joint disorders (TMD) through a case-control investigation. OSA is a sleep-related breathing disorder that affects breathing during sleep, whereas TMD involves pain and dysfunction in the jaw joint. Understanding any potential association between these two conditions could contribute to improved diagnostic and therapeutic approaches. A total of 50 participants were included in both the OSA group and the control group. Participants with diagnosed OSA constituted the OSA group, whereas individuals without OSA formed the control group. TMD symptoms were assessed using standardized diagnostic criteria. Statistical analysis was performed to compare the prevalence of TMD symptoms between the two groups. In the OSA group, 36 out of 50 participants exhibited TMD symptoms, whereas in the control group, 18 out of 50 participants displayed such symptoms. The calculated value was found to be 0.023, indicating a statistically significant association between OSA and TMD. The findings of this study suggest a notable association between OSA and TMD. Individuals with OSA are more likely to experience TMD symptoms compared to those without OSA. This underscores the importance of considering TMD symptoms in individuals with OSA and vice versa for a comprehensive approach to diagnosis and management.
