Cementoblastoma

The benign cementoblastoma (synonym: real cementoma ) is a benign, rare odontogenic tumor of ectomesenchymal origin and the only real new formation of cement-forming cells . According to the WHO classification of 1992, it is classified as a benign tumor of ectomesenchymal origin with / without odontogenic epithelial residues . It consists of cement-like tissue.

Cementoblastoma is characterized by an immediate relationship with the root and slow growth. It usually occurs on one side and can cause the jaw to swell. 61% of patients experience pain. The vitality of the associated tooth is usually positive. 75% of cementoblastomas occur in the mandibular, molar and premolar area .

In the X-ray image , the cementoblastoma shows a pathognomonic, characteristic appearance: It appears as a radiopaque (radio-opaque), usually round mass that is fused with the root of a tooth. Usually the tooth root is no longer recognizable within the opacity . The opacity is surrounded by a narrow, radiotranslucent border that is considered the growth zone. The size is between 0.5 and 5 cm, on average 1.4 cm. In the initial stage it appears rather radiotranslucent.

etiology

The causes of cementoblastoma are unknown. The age distribution includes all age ranges. 47% are diagnosed before the age of 20. Men and women are almost equally affected.
