Distribution and histologic character of osseous concavities in mandibular condyles of young adults.
Osseous concavities at the bone--articular soft-tissue interface were identified in 23% of 53 young adult TMJ condyles, with most occurring in the superior sector of the lateral and central aspects. All were filled with articular soft tissue, which provided a smooth articular surface without any evidence of surface breakdown. By extrapolation, radiographic evidence of osseous concavities in this age group should not be interpreted as evidence of articular surface breakdown (arthrosis). The long-term outcome of these concavities cannot be determined from this histologic cross-sectional study. However, the results support initial conservative therapy with monitoring over time.
