Answer: B. Cementoblastoma
Explanation
Cementoblastoma is a true benign neoplasm of cementoblasts forming a mineralized mass fused to tooth roots. Radiographic imaging typically reveals a well-defined radiopaque mass surrounded by a thin radiolucent rim. Although posterior teeth are most commonly affected, anterior jaw involvement can occasionally occur. Neoplastic cementoblasts proliferate and produce large amounts of cementum-like hard tissue attached to roots. Affected teeth usually remain vital despite the surrounding mass of mineralized neoplastic tissue. Surgical enucleation and extraction of the involved tooth are necessary to prevent recurrence.
Differentiating cementoblastoma from periapical inflammatory lesions is crucial to avoid unnecessary endodontic treatment. Oral and maxillofacial pathologists review biopsy specimens to confirm benign cementoblastoma diagnoses. Regular radiographic follow-up ensures complete removal and prevents recurrence of odontogenic tumors. Periapical granuloma is an inflammatory periapical lesion associated with non-vital necrotic teeth. Radicular cyst develops from epithelial rests of Malassez at the apex of a non-vital carious tooth. Chronic abscess presents as a localized collection of pus at the root apex of a non-vital tooth.
