Abstract
BACKGROUND: It is unclear that the influence of age on degenerative joint disease (DJD) of the temporomandibular joint (TMJ). METHODS: Relevant literature was retrieved from PubMed, Elsevier, Web of Science, and Google Scholar. EndNote 21 was used to consolidate the literature retrieved from these databases. Key information were extracted from the included studies, statistical analysis was performed using Stata 15.0. The quality of the studies was evaluated using the cross-sectional study evaluation criteria recommended by the Agency for Healthcare Research and Quality. RESULTS: A total of 11 studies involving 2832 participants (1099 males, 1744 females) were included. The incidence of DJD of the TMJ was approximately 35% among individuals aged 20 to 39, 43% among those aged 40 to 59, and 54% among those aged 60-69. CONCLUSION: Age progression is a key risk factor for the development of DJD of the TMJ. The incidence of DJD of the TMJ increases progressively across different age groups, with a significant rise observed in middle to older age groups.
