Benign cementoblastoma: A clinicopathologic evaluation

Abstract

The benign cementoblastoma is a neoplasm of cementum which has an unlimited growth potential. A review of the world literature reveals eight reported cases, and a clinicopathologic study of these eight previously reported cases and our two new cases suggests that this lesion is more common than previously thought but that it is not commonly recognized by clinicians. This clinicopathologic study suggests that the radiographic appearance of the lesion is pathognomonic and consists of a radiopaque mass surrounded by a thin radiolucent line. This mass is inseparable, radiologically, from the tooth root and is attached to it. Microscopic evaluation suggests that the lesion enlarges by peripheral growth, with the center of the neoplasm being more calcified and inactive than the periphery.
