Abstract

Objectives: This study aimed to describe the paraclinical (imaging) features of patients with temporomandibular joint disorders (TMD) who are indicated for stabilization splint treatment. Subjects and Methods: A cross-sectional descriptive study was conducted on 36 patients (18 years and older) diagnosed with TMD according to McNeil’s criteria, from May 2023 to October 2024 at the Department of Odonto-Stomatology, Hanoi Medical University Hospital, and the School of Dentistry, Hanoi Medical University. Results: On the frontal (coronal) plane, the triangular condylar shape was the most common (44.4%), whereas the round shape was the least common (9.7%). Bilateral asymmetric condylar lesions were observed most frequently (47.2%), followed by right-sided deviation (27.8%) and left-sided deviation (19.4%). An unaffected condylar head was the least frequently seen (8.3%). The mean anterior joint space was 1.50 ± 0.44 mm, the superior joint space was 2.52 ± 0.42 mm, and the posterior joint space was 3.03 ± 0.52 mm. Conclusions: In TMD patients, triangular condylar shapes and bilateral asymmetric condylar lesions were frequently encountered, whereas round condylar shapes and unaffected condylar heads were less common. Further studies with larger sample sizes are necessary to more accurately evaluate the prevalence and paraclinical findings in this patient population.
