Publication Abstract: 

Objectives: To compare the prevalence of TMJ osteoarthritic changes in CBCT images of TMD and non-TMD patients.
Study Design: A retrospective analysis of CBCT images of the joints of TMD and  non-TMD patients was performed. The presence or absence of osteoarthritic changes (condylar erosion, osteophyte, subcortical cyst, or generalized sclerosis) in each TMJ was evaluated. The prevalence within the two study groups were compared by using Chi-Square statistics.
Results: 78.6% of joints in the TMD group, and 79.7% in the non-TMD group had at least one type of osteoarthritic change. No significant difference was found in prevalence of osteoarthritic changes between the TMD and non-TMD groups in the overall study sample, nor within the subsets of gender and age groups.
Conclusions: The lack of a significant difference in prevalence of TMJ osteoarthritic changes in TMD and non-TMD patients highlights the equivocal relationship between osseous TMJ morphology and degenerative bone disease.
