Abstract

Objective: To study variations in the thickness of the roof of the glenoid fossa (RGF) in a group of patients with temporomandibular disorder (TMD) compared to a non-TMD group using Cone Beam Computed Tomography (CBCT).

Study Design: Comparative cross-sectional study.

Place and Duration of Study: Department of Prosthodontics, Armed Forces Institute of Dentistry (AFID), Rawalpindi Pakistan, from Jul 2024 to Jan 2025

Methodology: Based on inclusion criteria, 60 patients with complaints of TMD for the last two years were included in the study. After obtaining informed consent, the patients with temporomandibular joint pain (Group-A) were subjected to a full clinical evaluation and CBCT of the affected TMJ and the normal TMJ were requested from the Department of Radiology. Patients undergoing dental implant placement and those with orofacial pain unrelated to TMJ, like caries and sinusitis, requiring CBCT as part of their workup were included as controls (Group-B). CBCT reporting on all individuals was performed by a single investigator. Chi-square test and t-test were used to analyze data.

Results: Mean thickness of the RGF in patients with TMD was 1.850±1.096 mm which is significantly increased compared to 1.006±0.265 mm in non-TMD patients (p-value <0.001). Only one case of discontinuity of the RGF was recorded. The age and gender distribution matched closely in the two groups.

Conclusion: The study demonstrates a significant increase in Roof of Glenoid Fossa thickness in Temporomandibular Disorder (TMD) patients, suggesting its potential role as a diagnostic criterion in TMD.
