複合型齒瘤併恆齒高位阻生齒之治療－病例報告
Compound Odontoma and Permanent Impaction: A Case Report
摘要
齒瘤為口腔最常見的齒源性腫瘤。一般無症狀，多在例行的牙科X光檢查時被發現，若提早診斷，治療複雜性降低，預後較佳。手術完全移除後，少見復發。病例報告為11歲女性，因右上乳側門齒、乳犬齒延遲脫落，右上牙齦腫塊，接受環口X光檢查，發現右上乳側門齒、乳犬齒牙根底端多個類小牙狀X光不透性團塊，外圈由X光透性完整包覆，右上側門齒為高位橫向阻生，右上犬齒亦在高位，初步臨床診斷為複合型齒瘤併高位恆齒阻生。手術移除齒瘤後，露出右上側門齒，藉矯正向下牽引。歷時2年7個月，排齊右側上顎牙齒。術後環口X光檢查，齒瘤無復發跡象，未來應持續追蹤右上側門齒、犬齒牙髓活性與牙根吸收。

Odontomas are the most common odontogenic tumors in the oral cavity, usually asymptomatic and identified in the routine radiographic examination. Recurrence is rare after total surgical excision. Early diagnosis can help reduce the complexity of treatment and ensure a better prognosis. Here, we reported a case of an 11-year-old female referred from a local dentist. The patient suffered from delayed exfoliation of deciduous maxillary right lateral incisor and canine with bulging out mass on the right maxilla. Panoramic X-ray examination showed multiple radiopaque tooth-like structures in the radiolucent corticated border. Horizontal impaction of the maxillary right lateral incisor and a high level of canine was noted. The presumptive diagnosis was compound odontoma and high impaction of permanent teeth. After surgical removal of the odontoma, the crown of the impacted lateral incisor was exposed; downward traction was conducted subsequently. The orthodontic treatment spent two years seven months to align the maxillary right lateral teeth. Panoramic X-ray examination showed no recurrence tendency. Long-term follow-up of maxillary right lateral incisor and canine is necessary for monitoring pulp necrosis and root resorption.
