N2 - Aims: To assess the prevalence of degenerative bone changes in the temporomandibular joint (TMJ) of older adults using cone-beam computed tomography (CBCT), and to verify possible associations between these findings and patient health history. Methods: CBCT scans comprising both TMJs were acquired for 137 patients aged 65+, regardless of TMD status. Images were assessed by two oral radiologists and evaluated for the presence of flattening, erosion, sclerosis, subchondral cysts, and osteophytes in the TMJ bony components, and self-reported patient systemic health histories were retrieved from records. Results: There were 59 males, and the mean age was 73.35 ± 6.28. A total of 31.4% had bone changes in both TMJs, and 65.7% had bone changes in at least one side. Bone changes were more prevalent in females, with subchondral cysts (63.3%) and osteophytes (60%) the most common findings. There was a higher prevalence of osteoporosis/osteopenia (38.5%) and connective tissue disorders (39.8%) in patients with TMJ bone changes than in those with normal TMJs. Conclusion: Degenerative bone changes of TMJ were prevalent among older adults, and females were more affected. There was a greater prevalence of osteoporosis/osteopenia and connective tissue disorders in patients with TMJ bone changes than in subjects with normal TMJs.
