目的 评价序列治疗方法对外伤导致的根中1/3水平折断上中切牙的临床疗效,为更好地保留患牙的美观与功能提供参考.方法 外伤致根中1/3水平折断的上中切牙共20颗,折断线距根尖≥5 mm,采用手法复位后弹性夹板固定、根管预备后氢氧化钙制剂暂封、热牙胶根尖封闭、纤维桩根管内固定及树脂充填的序列治疗,随访观察0.5 ～2.0年.结果 20颗根折外伤牙中2颗断端对位良好,折断线完全消失,疗效为“愈合”;其余18颗折断线影像无明显改变,疗效为“有效”,无失败病例.所有外伤患牙均无异常松动与移位、无叩痛、牙龈无红肿、无窦道、无牙周袋形成.根尖X线片显示20颗患牙牙周、根尖均无异常.结论 上中切牙外伤根中1/3水平折断经序列治疗可获得较满意的治疗效果.
目的 評價序列治療方法對外傷導緻的根中1/3水平摺斷上中切牙的臨床療效,為更好地保留患牙的美觀與功能提供參攷.方法 外傷緻根中1/3水平摺斷的上中切牙共20顆,摺斷線距根尖≥5 mm,採用手法複位後彈性夾闆固定、根管預備後氫氧化鈣製劑暫封、熱牙膠根尖封閉、纖維樁根管內固定及樹脂充填的序列治療,隨訪觀察0.5 ～2.0年.結果 20顆根摺外傷牙中2顆斷耑對位良好,摺斷線完全消失,療效為“愈閤”;其餘18顆摺斷線影像無明顯改變,療效為“有效”,無失敗病例.所有外傷患牙均無異常鬆動與移位、無叩痛、牙齦無紅腫、無竇道、無牙週袋形成.根尖X線片顯示20顆患牙牙週、根尖均無異常.結論 上中切牙外傷根中1/3水平摺斷經序列治療可穫得較滿意的治療效果.

Objective To evaluate the clinical effect of sequential therapy for traumatized maxillary central incisor with horizontal mid-root fracture.Methods Twenty maxillary central incisors with horizontal mid-root fracture following dental trauma were included in our study.The distance between root fracture plane and root apical segment was more than 5 mm.The sequential therapy included stabilizing the traumatized incisor with a flexible splint after repositioning the coronal segment of the tooth,temporarily filling with calcium hydroxide after root preparation,sealing the root apex with warm gutta-percha obturation technique and internal fixation with fiber post combined with composite resin adhesion.The patients were followed for 6 to 24 months.Results Two cases healed without sign of fracture line and eighteen cases healed with sign of fracture line.No case failed.Abnormal mobility and translocation,percussion pain,gingival swelling,sinus tract and periodontal pocket were not observed in all the traumatized teeth.Radiology showed normal root apex and periodontium.Conclusions Sequential therapy for maxillary central incisor with horizontal mid-root fracture could acquire a satisfactory therapeutic effect.
