中文摘要 | 在乳齒根管治療中,傳統上以不锈鋼的根管銼針來進行根管清創及塑形。近年來,新的鎳钛旋轉器械也被應用於乳齒的根管治療上,但使用上應注意避免發生鎳钛銼針非預期斷裂的情形。本病例為一位六歲一個月大的男童,在右下第一乳臼齒有一斷裂的鎳钛根管銼針逸出其遠心側根管外,並合併牙根吸收的情形,因而拔除乳臼齒並取出斷針。本文也回顧相關文獻,針對造成鎳钛根管銼針斷裂的可能原因及如何取出斷針做一般討論。 |
英文摘要 | In the endodontic treatment of the primary teeth, stainless steel files were used traditionally for root canal debridement and shaping. Recently, Ni-Ti rotary instruments were also applied in the treatment. However, cautions must be taken to avoid unexpected fracture of the Ni-Ti files. This report presented a six-year-one month old boy with a broken Ni-Ti instrument beyond the distal canal of the lower right primary first molar concomitant with root resorption. We extracted the tooth and removed the broken file. The possible causes of separation of Ni-Ti rotary instrument and the techniques to remove broken files were discussed. |
