Peripheral osteoma arising in the mandible is relatively rare. This study will report on one case of solitary peripheral osteoma located in the mandibular body around the mental foramen. The patient was a 48－year-old woman who was referred to our hospital because of pain in the alveolar membrane near mental foramen from the placement of a removal partial denture. Hard swelling on the right side of the mandible was palpable. A CT showed that a pedunculated bony swelling in the right mandibular body existed around the right mental foramen. It was removed surgically using an ultrasonic bone cutting tool via an intraoral approach with the patient under general anesthesia. The histopathological diagnosis was a compact osteoma. There was neither paresthesia nor recurrence postoperatively at a follow-up examination after one month.
