cementoma /sē′mentō″mə/ pl. cementomas, cementomata [L, caementum + Gk, oma, tumor] , any benign, dysplastic cementum-producing tumor associated with the apices of teeth. It may be present as a mass of fibrous connective tissue, as fibrous connective tissue with spicules of cementum, or as a calcified mass resembling cementum. Radiographically, early cementomas appear as well-defined radiolucencies at the apex of mandibular anterior teeth that are often mistaken for periapical lesions. Older lesions may appear to calcify with time. An important diagnostic indication is that these teeth test vital to vitality testing. Kinds include cementoblastoma, cementifying fibroma.
