中文摘要 | C形態下顎第二大臼齒的根管解剖構造,對於根管治療是很大的挑戰,除了清創與充填均較 一般根管複雜,若一旦非手術性根管治療失敗須介入手術性根管治療時,除了其位置操作不易及 視野不佳,會大幅增加手術的難度外,其周圍的解剖構造又是另一項限制,因此,在許多狀況 下,對於下顎第二大臼齒施行傳統的根尖手術被認為是禁忌症,因此在對患齒進行嚴格的條件篩 選之後,蓄意再植術是手術性根管治療另一個可行的術式。本文報告一右下第二大臼齒C形態根 管在根管再治療過程中不慎將大量馬來膠針推出根尖,非手術性根管治療在此限制下無法順利完 成並移除根管外之馬來膠針,因此利用蓄意再植術移除不慎推出之馬來膠針後再完成根管治療, 經二十個月追蹤目前預後良好並持續追蹤中。 |
英文摘要 | The complex configuration of C-shaped root canal systems is difficult to clean, shape and obturate completely. Moreover the conventional endodontic surgery of the mandibular second molar is a challenge because of anatomic limitation and unfavorable operative field. Once the conventional endodontic treatment of the mandibular second molar has failed and needs to receive surgery, intentional replantation is an alternative option. This case report describes endodontic retreatment in a right mandibular second molar with a C-shaped root canal system and an apical radiolucent lesion. The guttapercha had accidentally extruded and should be removed surgically. According to carefully evaluation and examination, intentional replantation in right mandibular second molar was performed. After twenty months follow-up, the prognosis shows good. |
