Assessment of Osseous Changes Using Cone Beam Computed Tomography in Patients with Temporomandibular Joint Disorders

Abstract Aim: The aim of the study was to investigate various osseous changes using cone beam computed tomograms in patients with temporomandibular joint disorders. Method: The study was conducted on 72 patients of both genders (37 females and 35 males) with age range in between 11-70 years having history of TMDS. Various osseous changes were evaluated in terms of condylar erosion, condylar flattening, osteophyte, joint mice, cyst, age related changes and surface irregularities. Also, joint space measurements were made in terms of anterior, posterior and superior relation. Results: The results showed 45.83% erosion, 20.83% condylar flattening, 1.38% joint mice, 44.44% surface irregularities, 8.33% age related changes and 18.05% osteophytes. Also, maximum number of changes was seen in the age group 21-30. Conclusion: The most common finding was condylar erosion and surface irregularity. Joint space was reduced in TMDs as compared to normal subjects and its was lower in right TMJ in males and left TMJ in females. CBCT found to be effective in assessing joint space measurements as well as determining all features of joint pathology that can be helpful in better patient evaluation and treatment planning.
