摘要

牙瘤是一種常見的混合齒源性腫瘤，含有牙釉質、牙本質及不定量的牙骨質和牙髓組織。當這些組織形成許多畸形類似牙齒的構造時，稱之為複合性牙瘤，但若這些組織只是無秩序的聚成一團，則稱之為混合性組合牙瘤。本篇報告做了文獻回顧以及敘述一位10歲位於下顎犬齒及小臼齒區的複合性牙瘤患者，其臨床、X光片及電腦斷層判讀、手術方法、組織學檢查及術後追蹤，並探討發生位置、各種併發症及處理方法。術後追蹤顯示阻生牙明顯往上萌發且大量修正其萌發路徑，早期發現及摘除可避免嚴重的併發症產生。

Odontoma is one of the common types of mixed odontogenic tumors. It is composed of enamel, dentin, and variable amounts of cement and pulp tissue. A compound odontoma is composed of multiple small malformed tooth structures; whereas a complex odontoma has an irregular mass in a disorderly pattern. This paper presents a 10-year-old girl with compound odontoma involving lower canine and premolar area. The clinical, radiographic (CT scan), and histological findings were described and discussed. The result of this case after surgery was good. Early detection and intervention was recommended for preventing further complications.
