Combined benign odontogenic tumors: CT and MR findings and histomorphologic evaluation.

Calcifying epithelial odontogenic tumors and calcifying odontogenic cysts are rare, benign odontogenic tumors. We report two cases of an exceptional combination of these tumors with either an ameloblastic fibroodontoma or an odontoma.

[Lesions of the inferior alveolar nerve during extraction of the wisdom teeth. Consequences--prevention].

Neurological consequences of extractions of the third inferior molar can be severe. Progress in imaging techniques has made it possible to identify molars << at risk >>. Extraction by wear without removal of the apex is proposed as a means of avoiding damage to the alveolar nerve.

[Mandibular osseous lacuna, salivary inclusion].

Salivary inclusion is seen, on panoramic films of the maxilla and the mandible, in the form of a mandibular osseous lacuna. Such an indicative diagnostic image, the prognosis for which is often sobering, requires CT scan exploration. The latter permits the diagnosis of Stafne's lacuna, the nature of which is benign.
