Introduction: Gingival actinomycosis is a rare disease caused by Actinomyces israelii in the oral cavity.
Case Report: A 42-year-old healthy man without underlying diseases or any teeth troubles suffered from severe pain in the gingival of the right mandibular bone for three weeks. The intraoral inspection revealed a well-defined elastic hard mass with a size less than 10 mm on the medial side of the right mandibular gingiva. The histopathological examination proved that the bacterial druse with radial structure invaded the bone margin widely and proliferated in some places of the bone. After removing the mass and scraping off the around bone, followed by two month-oral use of Amoxicillin (AMPC:1500 mg/day), his complaints and the gingival tissue have been entirely resolved.
Conclusion: The morphological features of the growth of actinomyces in the bone margin by the limited lesion of actinomycosis at the gingiva have not ever been reported. Even localized actinomycosis at gingiva should be adequately treated.
Keywords: Actinomycosis, Amoxicillin, Druse, Gingiva
