中文摘要 | 當牙齒因外傷而造成牙齒內縮時,易對牙周韌帶以及牙髓組織造成嚴重的傷害,進而導致 牙髓壞死和牙根吸收。適時進行根管治療並置放氫氧化鈣糊劑,在大多數的狀況下都可以讓牙根 吸收的情形獲得改善,但仍有部分病例會因嚴重的牙根吸收導致根管穿孔(perforation),造成預 後不佳。本文為因外傷而導致牙齒內縮的上顎前牙,發生牙根外吸收(external root resorption)的 併發症並造成穿孔,經由傳統根管治療配合置放氫氧化鈣,並以三氧礦聚合物(mineral trioxide aggregate, MTA)修補根管穿孔部分,門診追蹤顯示預後良好。 |
英文摘要 | The traumatic intrusion of permanent teeth cause severe damage to the dental structure, periodontium and pulpal tissues. Pulp necrosis and root resorption may be the sequella of intrusion. In most cases, the intervention of endodontic treatment in appropriate time and intracanal medicament with calcium hydroxide could effectively resolve the complication of root resorption. However, other cases may result in root perforation due to severe external root resorption. Prognosis of these teeth will be poor. This case report present the management and the treatment outcome of traumatically intruded incisor, which occurred external root resorption and eventually resulted in root perforation. After conventional endodontic treatment and the placement of calcium hydroxide, repair of the root perforation with Mineral Trioxide Aggregate (MTA) was performed. After 8-months follow-up, the intruded incisors showed arrest of external root resorption with normal periodontium. |
