Abstract
Background: Temporomandibular disorder (TMD) is a cumulative terminology that demonstrates musculoskeletal and neuromuscular disorders. It is of extreme relevance that the number of subjects with TMD-related pain has noticeably increased over the recent years. This could be attributed to the increased stress in lifestyles and use of electronic devices (smartphones/laptops/tablets), altering the posture across the boundaries of age, gender, and geography. Thus, this systematic review and meta-analysis was conducted to derive the prevalence of TMD disorders across the aforementioned boundaries.
Methods: The method used in this study to quantify the prevalence of TMD across the countries and populations was in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. MEDLINE, Scopus, Web of Science, and Google Scholar were systematically searched until July 30, 2024.
Results: The quality of the prevalence studies was assessed using Critical Appraisal Skills Programme (CASP) Tools. The bias within the study data was evaluated using RevMan software, and the prevalence was calculated as 25.8%. Finally, the forest plot was employed to determine the weightages and risk ratios of the studies.
Conclusion: Based on the findings, there has been a slow and steady increase in the prevalence of TMD, and thus sustainable measures are imminent for controlling this disorder.
