Prevalence of Abnormal Morphology of the Temporomandibular Joint in Asymptomatic Subjects: A Retrospective Cohort Study Utilizing Cone Beam Computed Tomography.

Purpose: This retrospective cohort study in an asymptomatic nonpatient population evaluated the prevalence of specific morphologic changes usually associated with the presence of degenerative joint diseases (DJD) using cone beam computed tomography (CBCT) and examined the associations between DJD and age, sex, and number of teeth present.

Materials And Methods: CBCT images (268 TMJs) of 134 asymptomatic patients were studied. Patient data were obtained from clinical records, and calibrated examiners interpreted the CBCT images.
