title: Periapical actinomycosis.
abstract: Two cases of actinomycotic lesions of the periapical tissue in relation to the molars are described. The difficulty in obtaining a positive culture for actinomycetes in spite of definite histologic evidence of actinomycosis is highlighted. Besides antibiotics, the importance of planned treatment to deal with the underlying diseased periapical tissue and the tooth is emphasized.
