| Abstract | Odontomas are considered to be developmental anomalies (hamartomas), rather than true neoplasm, composingof both epithelial cells and mesenchymal dental hard tissues. The prevalence of odontoma at 20.1 % is regardedas the second most common tumor occurring in the oral cavity. Based on pathological conditions, odontomasare classified into two types, compound odontomas and complex odontomas. This study investigates the case ofa 19-year-old Thai female who was referred to the department of oral and maxillofacial surgery at Chiang MaiUniversity and presented with a swollen right cheek that developed gradually. Without any previous symptoms,the tumor was accidentally detected from a radiograph during an orthodontic treatment in a private clinic. Thepatient’s past medical history showed no underlying disease or drug allergy. The clinical examination revealedfacial asymmetry with swelling present on the right buccal area, normal skin texture, no tenderness, and noabnormal sensation. An intraoral investigation revealed a bony-hard swelling of the right mandible from distalof the mandibular right second molar to the ramus of mandible; however, the mandibular right third molar wasnot found during the clinical examination. The panoramic radiograph exhibited a unilocular nonhomologousradiopaque lesion with a well-defined margin and an expanded border to the right mandible. The inferior alveolarcanal and the mandibular right third molar were displaced inferiorly to the inferior border of the mandible. Anincisional biopsy was performed under local anesthesia and the diagnosis showed it was complex odontoma. Theodontoma was enucleated by extraoral approach. After the lesion had been removed, internal fixation was doneusing a reconstruction plate. The patient had no pain or postoperative paresthesia during a 12-month follow-upperiod. As such, the removal of the reconstruction plate was carried out 18 months after the surgery. In conclusion,this case is a rare incidence of large odontomas at the right angle of the mandible. Despite its large size, conservative treatment with a reconstruction plate to prevent a pathologic fracture yielded satisfactory results, which isconsistent with other studies in literature. |
