A cementoblastoma, one of many mandibular lesions is a rare tumour of the cementum, originating from the root and slowly enlarging. It therefore obliterates the periodontal ligament space.
It is typically radiodense with a rounded or sunburst appearance, and a relatively radiolucent rim. Usual occurrence is around the apex of the premolars in young patients (less than 25 years of age).
They can be very similar in appearance to ossifying fibromas.
