Abstract
Jaw actinomycosis is caused by Actinomyces israelii, an indigenous oral bacterium. Here, we report a case of jaw actinomycosis after tooth extraction. The patient was a 35-year-old man who was referred to our hospital in February 20XX for wisdom tooth extraction. The lower left 8 tooth was extracted under local anesthesia. At the end of March 20XX, the patient’s left cheek became swollen, and he was referred to our hospital. The left buccal region showed indurated swelling and difficulty opening the mouth. Blood tests revealed inflammatory reactions. Additional tests for suspected diabetes based on body size reveled HbA1c level of 9.4％ and fasting blood glucose level of 318mg/dL. Osteomyelitis was suspected, and anti-inflammatory treatment was initiated using antimicrobial agents. Since there was no improvement, biopsy was performed, and jaw actinomycosis was diagnosed. The patient had a history of uncontrolled diabetes mellitus, which may have contributed to the disease onset.
