title: Benign cementoblastoma involving multiple maxillary teeth: report of a case with a review of the literature.
abstract: A rare case of benign cementoblastoma involving multiple deciduous and permanent teeth is presented with a review of the literature. A 12-year-old boy was admitted for a swelling in the right maxillary premolar-molar region. A radiologic examination revealed a well-defined, round, radiopaque mass extending from the right maxillary first premolar to the second permanent molar. The tumor was removed with all associated teeth. A histologic examination of the surgical specimen revealed a well-circumscribed tumor composed of cementum-like tissue surrounded by a fibrous capsule. The tumor was attached to the roots of the second deciduous molar, first premolar, and the first and second permanent molars and embedded in the crown and root of the right maxillary second premolar, suggesting that the lesion had arisen from the second deciduous molar. There has been no recurrence of the lesion more than 18 months after the surgical procedure.
