Abstract: The present study's aim was to compare temporomandibular joint (TMJ) images for individuals with and without temporomandibular disorder (TMD) using high-resolution ultrasonography (HRUS). The distance between the lateral-most point of the articular capsule and the lateral-most point of the mandibular condyle (lateral capsule-mandibular condyle distance) was determined to confirm the clinical diagnosis according to the Diagnostic Criteria for Temporomandibular Disorders (DC/Two). The sample group comprised 17 women and 15 men, aged 19-39 years, distributed into TMD (n = 20) and Asymptomatic (n = 12) groups. The evaluations were in closed- and open-mouth positions. The lateral capsule-mandibular condyle distance was measured in both positions. The articular surface of the condyle and the articular capsule were visualized as hyperechoic structures, and the articular disk was visualized as a central, hyperechogenic area surrounded by a hypoechoic linear image. Morphological changes were observed in some TMD group participants, including joint effusion (hypoechogenic area), condylar erosions (increased hyperechoic area), and condylar surface irregularities. The lateral capsule-mandibular condyle distance did not differ between sides or groups among participants with intra-articular disorders with or without pain (P > 0.05). In conclusion, HRUS allowed visualization of the TMJ structures, but did not allow confirmation of clinical diagnosis by DC/TMD.
