Abstract
Objective: The aim of this study was to evaluate the prevalence of temporomandibular joint (TMJ) disorders in a sample of the Lebanese population. Materials and Methods: This study analyzed data of TMJ disorder rates and their links to age and sex from 689 patients referred to a private dental clinic in Beirut, Lebanon, from 2012 to 2017. Results: The overall prevalence was 17.8%, with disc displacement with reduction (DDR) most common (10.2%), followed by myalgia (6.4%) and disc displacement without reduction (DDwR) (1.2%). Prevalence peaked in the 46–60 age group (27.5%) and showed no significant gender difference. Conclusion: This study highlights a significant prevalence of TMJ disorders among Lebanese dental patients, particularly in older age groups, underscoring the need for targeted interventions, early diagnosis, and tailored treatment strategies to improve patient care and inform future research.
