A radicular cyst is characterized as an odontogenic cyst of inflammatory origin that develops from Malassez epithelial rests in the periodontal ligament as the consequence of dental pulp inflammation. The cyst commenced in the carious tooth and spread to the periodontal and periapical regions. The majority of these lesions appear as precise radiolucencies and encompass their entire apex. The cystic lesion, which is also called a root-end cyst or periapical cyst, is sometimes referred to as a true cyst because it is lined by fluid epithelium. There are several treatment options to address radicular cysts, including surgical and nonsurgical methods. In this case study, we described the clinical observation of the cyst. The cyst typically manifests in later life due to its prolonged etiology. The maxillary anterior region is the most frequently utilized site.
