title: Actinomyces-associated calcifications in a dentigerous cyst of the mandible.
abstract: Actinomyces-associated lesions in the jaw, such as radicular cyst and osteomyelitis, have been reported by many authors. The lesions are caused by infection from peripheral sites and can be seen to contain Actinomyces druses on pathologic examination. To our knowledge, no previous reports have described Actinomyces-associated calcification in the jaw, although the lesions in the jaw often include druses. We report here a rare case of Actinomyces-associated calcifications in a dentigerous cyst of the mandible.
