Objective: To establish the prevalence of changes in the articulation temporomandibular joint (TMJ) and its association with age, sex, and right side or left side, using panoramic radiographs.  Materials and Methods: We reviewed a total of 360 (720 condyles) x-rays of both sexes and older than 18 years, grouped in three categories, 18 – 40 years, 41 – 60 years and older than 61 years. Will evaluate bone changes of the condyle of the mandible as a subchondral cyst, flattening, erosion, sclerosis and osteophyte.  Results: The prevalence of bone changes of the mandibular condyles was 70,3% being more frequent in the 41-60 years, and in males, finding statistically significant differences. The number of condyles affected was 419 (58.2%). Although both condyles were found affected, for the most part, there were no differences statistically significative on hand. The most common change w...
