Articular Eminence Inclination and Glenoid Fossa Measurements by CBCT in Patients with Temporomandibular Joint Disorders

Background: The increasing frequency of temporomandibular joint dysfunction requires the promotion of diagnostic and therapeutic approaches. The several etiologies of dysfunction are still poorly understood. Numerous studies have talked articular eminence shape as a probable causative factor for this dysfunction. Aims of the study: The aim of this study was to measure of articular eminence inclination, depth of glenoid fossa and width by cone beam computed tomography in patients with temporomandibular joint disorder conferring gender and side and compared with healthy control. Patients and Methods: Study samples embraced of fifty-five individuals (110 joints), were twenty patients with intra articular disorders of temporomandibular joint, fifteen patients with degenerative disorders of temporomandibular joint and twenty control group with age range from (20-55) years old. Results: The results display females appear to stay more affected by disorders of temporomandibular joint. The articular eminence inclination showed higher mean value in the right side than left side and in males than females. Also, glenoid fossa depth and width was higher mean value in the right side than left side and in males than females. The results recorded mean value of articular eminence inclination in control group higher than patients with temporomandibular joint disorders, while mean value of glenoid fossa depth and width in control group less than patients with temporomandibular joint disorders. Conclusion: Females look to be more affected by temporomandibular joint disorders. The glenoid fossa width and depth were also less in the control individuals.
