ObjectivesTo assess the prevalence of temporomandibular disorders (TMD) discovered incidentally during routine dental examination, identify disease patterns, and evaluate patients' attitude toward accepting treatment.Study designA total of 3009 subjects were examined at the University Dental Hospital Sharjah. Research Diagnostic Criteria for TMD (RDC/TMD) Axes I and II were used for assessment. Subjects with acute/serious dysfunction symptoms underwent cone-beam computed tomography (CBCT) examination. MRI was used to confirm the diagnosis of disc displacement.ResultsNon-self-reported TMD prevalence was 10.8% (n=325). Among TMD patients, the disorders were diagnosed more in women (65.85%) (p<0.05), and between the ages of 25 and 45 (65.54%) (p<0.05). Axis I assessment revealed disc displacement with reduction (group IIa) was the most common (40.92%). Axis II chronic pain grade (CPG) showed 32.62% of TMD patients experienced chronic pain, whereas 66.77% had mild disability. Interest to pursue treatment was indicated by 92.31% of patients. CBCT and MRI assessment changed the primary diagnosis in 26.08% and 18.47% of cases, respectively.ConclusionsTMD screening during routine dental examination led to the diagnosis of non-self-reported TMD, most commonly related to disc displacement with reduction. Radiographic assessment was important to confirm TMD diagnosis. Patients diagnosed with TMD during dental screening expressed interest in pursuing treatment.
