Abstract :AIM The aim of this study is to evaluate the presence and findings of osteoarthritis based on CBCT images according to different age and gender groups. MATERIAL AND METHODS CBCT images of 764 temporomandibular joints (TMJ) were analyzed retrospectively. Osteoarthritis (OA) findings were grouped as normal or flattened, erosion, sclerosis, subchondral cyst, and osteophyte. These groups were evaluated separately for both sexes and for five separate decades. RESULTS While pseudocyst and flattening among osteoarthritis findings were more common in men, sclerosis was significantly more common in women (p<0.05). Osteoarthritis findings were rarely observed in the 20-29 age group. While erosion and flattening were significantly higher in the 60-69 age group, sclerosis was observed at a higher rate in the 50-59 age group (p<0.05). CONCLUSIONS In women, sclerosis as a sign of OA, and in men, flattening is in the foreground. While the frequency of normal articular eminence decreased regularly with age, flattening, erosion and sclerosis were observed as signs of OA with an increasing rate in advanced age.
