摘要

由於乳臼齒錯綜複雜的根管系統，因此其根管治療一直是引起爭議的。當有根尖周齒槽骨之破壞，甚至膿腫產生時，通常牙醫師就需面臨是否拔牙的抉擇。然而拔牙後，空間處理的問題有時會不知所措。本篇病例報告，乃針對膿腫併根尖有病變之乳臼齒，在不同於拔牙的考量下，經由適當的乳牙根管治療，及齒齦下刮除術、排膿、沖洗，乳牙復形，並在日後持續的觀察。結果發現不但牙周組織恢復健康，其牙齒大都能維持正常功能，達到乳牙本身咬合及維持空間的重要功能，維持至換牙。故以此方式治療此類乳臼齒，不僅病患家屬滿意度提高，也可避免因拔牙所造成空間處理上的問題。

Due to the complicated nature of primary root canal systems, the pulpal treatment of primary teeth has been controversial. When there is alveolar bone destruction and even abscess formation, dentists usually encounter the dilemma of extraction or maintaining the tooth due to the space problem after extraction. This article presents a 5-year-old girl with abscessed primary molars with radicular lesions successfully treated by primary endodontic treatment with subgingival curettage, pus drainage, irrigation, and final restoration with long-term follow-up. This treatment regimen was contrary to the traditional method of extracting this kind of tooth. The results showed that the periodontal tissue was healed and healthy and the dentition was functioning normally. These primary molars survived to continue their important roles of maintaining normal occlusion and space. Therefore, treatment of an abscessed primary molar in this way not only enhances the satisfaction of the parents, but also avoids the inevitable space problem following extraction of a primary molar.
