Abstract

Background:  CBCT is less costly and the dose of radiation is lower; the amount of radiation varies according to the brand of the appliance and the structure to be imaged. The aim is to evaluate the diagnostic ability of Digital OPG in comparison with CBCT for diagnosing the condylar osseous changes in patients with TMJ pain and to assess their prevalence amongst males and females. Materials & Methods: A total of 80 condyles were included in the study with complaint of pain in TMJ. Detailed clinical examination was done. The patients clinically suspected to have TMJ pain was subjected to Digital OPG and CBCT and all good quality radiographs was included in the study. The TMJs were assessed as follows: 0normal;1-erosion;2-flattening;3-osteophytes;4-sclerosis5-resorption;6- anyother changes. Results: The results of our study showed, there exists a definite correlation between the morphological changes of condyle and TMJ pain and these changes showed slight inclination towards females. OPG could even detect the gross bony changes such as flattening, large erosions and osteophytes, whereas CBCT could detect condylar changes like erosion, bifid condyle and Ely’s cyst more precisely and accurately Conclusion: CBCT provides more precise, accurate and valid information of condylar changes than OPG and it was also found the existence of correlation between TMJ pain and morphological changes of condyle.
