Usage of CBCT in Diagnostic Dilemma: A Case Report

Abstract

Dentigerous cysts are a common type of odontogenic cysts that arise from the follicle surrounding an unerupted tooth. Although they are typically asymptomatic, they can cause tooth displacement, resorption, and even facial disfigurement in rare cases. In this case report, a 20-year-old male presented with a diffused swelling in the lower left cheek region that gradually increased in size over five days, along with pain and difficulty in mouth opening. A cone-beam computed tomography (CBCT) imaging was performed, revealing a well-circumscribed, unilocular radiolucent lesion consistent with a dentigerous cyst surrounding the crown of the impacted tooth 38. The therapeutic approach for dentigerous cysts varies depending on the cyst's dimensions and location, the patient's age, and the cyst's proximity to adjacent vital teeth. Conservative surgical approaches are preferred for younger patients, while cyst/tooth removal is the treatment of choice for older patients. In conclusion, proper interpretation of radiographic images is critical for diagnosing dentigerous cysts and developing appropriate management plans
