Abstract
Actinomycosis (ACT) is a chronic infectious disease characterized by spread to contiguous tissues and multiple draining sinus tracts. Periapical ACT is extremely rare. An 18-year-old female patient was referred to the oral pathology service with a complaint of swelling of 3 years' duration on the right side of the palate. Intraoral examination revealed a sinus tract in the periapical region of maxillary incisors. Periapical radiography revealed a large periapical radiolucency associated with endodontically treated tooth #12. Teeth #13, #14, #11, and #21 were noncarious and positive to thermal stimuli. Osteotomy under local anesthesia was performed, and granulomatous tissue exhibiting yellowish masses was removed and sent for microscopic examination. The diagnosis was periapical ACT. The patient returned after 2 weeks; the healing was uneventful, with no signs of infection. Radiographs obtained 5 months later showed incomplete regeneration of the apical bone. The patient was referred for endodontic retreatment. Support: FAPEMIG
