Benign cementoblastoma in a primary lower molar, a rarity

Abstract

An asymptomatic radiopacity surrounded by a radiolucent line was observed from a panoramic radiograph of an 11-year-old girl. The lesion was associated with the mesial root of the lower right second primary molar. The radiographic appearance of the lesion suggested a benign cementoblastoma. Histological diagnosis after surgical excision of the tumour and extraction of the tooth confirmed the radiographic diagnosis. Benign cementoblastomas associated with primary teeth are extremely rare lesions. To our knowledge, only eight cases have been reported in the literature.
