<unk>  is a relatively rare benign neoplasm of the cementum of the teeth.<unk>  is derived from ectomesenchyme of odontogenic origin. According to the World Health Organization,<unk>  is classified as a true cemental neoplasm. True cemental neoplasms may be classified into 4 categories: benign<unk> , cementifying fibroma, periapical cemental dysplasia, and gigantiform cementoma.<unk> s are uncommon neoplasms and account for approximately 0.69%–8% of all odontogenic tumors. Common complications of<unk>  include bleeding, nerve injury, and malocclusion. X ray is the imaging modality of choice for<unk> . On x ray, characteristic findings of<unk>  include well defined, markedly radiopaque mass, radiolucent peripheral "line" which overlies and obliterates the tooth root, apparent external root resorption, and severe hypercementosis. Surgical tooth extraction in conjunction with post-surgery biopsy is the most common approach to the treatment of<unk> .
