title: Extensive bone loss associated with periapical infection with Bacteroides gingivalis: a case report.
abstract: A case is presented in which rapid and extensive bone loss occurred around a maxillary molar with periapical infection by Bacteroides gingivalis (Porphyromonas gingivalis). The lesion failed to respond to conventional endodontic therapy. An adjacent vital molar was extracted and an unfavourable periodontal condition occurred despite microbiological investigation and surgery.
