摘要

融合牙是在乳齒列當中最普遍地牙齒異常之一，但發生在上顎兩側門齒時屬罕見。其病源學並不清楚。此病例是一位4歲大的男童，擁有上顎兩側乳門齒之牙融合。其右上牙融合因齲齒延展至牙髓而必須根管治療。對於牙融合根管形態精確地辨別下，才能徹底清創。在乳齒列牙融合存在與恆齒列的高度異常有相關性，因此這類異常的早期診斷是相當重要的，並且應小心地臨床及X光追蹤檢查，才能在適當時機給予適切的治療。

Fusion is the one of the most common dental anomalies in the primary dentition and it is very rare when it appears on the maxillary bilateral incisal areas. The etiology of fusion is unclear. The case was a 4 year-old boy with caries involvement on the bilateral maxillary fused primary incisors. The right maxillary fused tooth had to be treated with endodontic treatment due to caries extending to the pulp. The root canals of fused tooth were thoroughly debrided under the exact differentiation of the root canal morphology. The presence of fused tooth in the primary dentition is associated with a high of degree of anomalies of the permanent dentition. Early diagnosis of the anomalies is, therefore, of considerable importance, followed by careful clinical and radiographic observations and adequate intervention in the appropriate time.
