“Intraoral actinomycosis” is considered to be a rare disease. Eight cases of intraoral actinomycosis diagnosed histopathologically are reported. Four cases occurred at the periapical region and the other four occurred at the submucosal region. Sulphur granules were clinically found in the pus or granulation tissue. Associated lesions were pericoronitis, radicular cysts, marginal periodontitis, and sequestra. Infected material and causative factors were surgically removed from the site. Long-term antibiotic therapy was not required in any patient.
