Abstract
Subchondral cysts are frequently encountered in patients with temporomandibular joint osteoarthritis (TMJ OA), particularly in advanced stage. Subchondral cysts within osteoarthritis are typically lying adjacent to the joint surface where initial load bearing occurs during activity and have been associated with greater pain and disease progression. Although the etiology of these cysts remains uncertain, recently studies report that the induction of the subchondral bone mechanical stress caused subchondral cysts. Repeated overloading leads to further deterioration of subchondral bone which render subchondral bone structure more fragile, increase the risk of osteoarthritis progress. The purpose of this study was to assess the effect of conservative treatment and longitudinal osseous changes of a large subchondral cyst in a mandibular condyle in a symptomatic TMJ OA patient.
