Reparative Granuloma

The cause of reparative granuloma is unknown, but it is probably secondary to local trauma, such as tooth removal. The peripheral form is a sessile or pedunculated mucosa-covered reddish or bluish mass arising from the gingiva or alveolar mucosa, and it is most common on the anterior mandible. The central form is endosteal, usually anterior to the first molar in the mandible. Radiographically, the lesion appears as a lytic, expansile, unilocular cavity with well-demarcated nonsclerotic margins and a bony cortex, which is thinned but intact. Treatment consists of curettage.
