48例完全脱位牙再植疗效观察

An evaluation of the clinical effects of replantation on treatment of complete dislocated tooth

目的：观察外伤后完全脱位牙再植的临床疗效。方法：对2006年以来到我科就诊的48例52个完全脱位牙，经常规处理后再植复位固定，随访观察2～3年。结果：52个脱位牙再植后经2年以上复查，成功48个，失败4个，成功率92％，离体时间2h内再植成功率高于2h后（P〈0．05），湿保存较干保存再植成功率高（P〈0．05），离体时间越短牙周膜愈合情况越好（P〈0．05）。结论：离体时间短、合适的保存介质、牙根面良好的牙周膜活性是完全脱位牙再植成功的重要因素。

AIM： To evaluate the clinical effects of replantation on the treatment of completely dislocatedtooth. METHODS ： Forty-eight patients with 52 teeth were included since 2006, all the teeth were replanted and fixed after being treated with conventional processing and were evaluated during postoperatively follow-up . RESULTS ： Fifty-two teeth were followed-up for 2 years. The success rate was 92% （48 successful and 4 failed）. The success rate of replantation within 2 h was higher than ≥2 h （P 〈 0.05）, Wet storage of the tooth showed higher success rate than dry storage （P 〈 0.05）. CONCLUSION： The timing of replantation, tooth storage method and the activity of periodontium olav important roles in successful replantation
