摘要

雙重齒是乳齒列常見的牙齒異常現象。乳齒列雙重齒的存在容易導致乳齒有齲齒、不美觀、空間分佈及牙根延遲吸收的問題。而繼生齒可能產生的變異包涵缺齒畸形及再次產生雙重齒，這通常也是父母最關心的問題。本病例報告為上顎乳門齒及乳側門齒呈現融合齒的治療。在預防醫療的考量上，建議在雙重齒的溝隙中使用裂溝封填劑，定期口腔檢查以避免乳齒列雙重齒延遲脫落造成繼生齒阻生或萌發異常。

A case of upper primary central incisor and lateral incisor fusion is presented. In the preventive concern, application of sealants over fissures of double teeth is suggested.
