title: Actinomycosis associated with a root-treated tooth: report of a case.
abstract: An unusual case of a persistent infection related to a root-filled tooth is reported. Microscopical evaluation revealed the cause to be a large mass of Actinomyces-like filaments, and microbiological culture yielded a low level of Actinomyces israelii. The significance of such a presentation is discussed.
