摘要： 目的:探讨儿童及青少年牙齿完全脱位后不同处理方法与再植效果的相关性。方法:选取2015年1月~2017年12月因完全牙脱位于我院就诊的患者90例,探讨患牙保存介质、脱位时间与再植预后的相关性。结果:在127颗再植牙中,87颗治疗成功(68.50%)。牙根未发育成熟的患牙(80.36%)再植成功率高于牙根发育成熟的患牙(59.15%,P＜0.05)。受伤后30 min内的再植成功率(91.49%)高于30 min～2 h(68.89%)及脱位2 h后(37.14%)的再植患牙(P＜0.05)。患牙经牛奶储存后的再植成功率(93.02%)高于生理盐水(70.00%)、含于口腔内(68.18%)和干燥介质(34.38%,P＜0.05)。结论:牙根未发育成熟的脱位牙再植成功率较高;牙脱位后30 min内再植预后较好;将脱位牙存储于牛奶中能获得较高的再植成功率。

Abstract: Objective: To elaborate the correlation between post-traumatic treatment factors and the success of dislocation tooth replantation. Methods: The samples that used to analyze the relation among preservation medium, time, and treatment outcomes were selected from 90 patients in our hospital due to trauma from January 2015 to January 2017. Results: Children from six to twelve were at high risk of tooth dislocation. The most common causes of tooth dislocation included falling on the ground(44.4%)and traffic accident(35.5%). The replantation success rate of immature tooth (80.36%) was higher than that of the mature tooth (59.15%). The success rate (91.49%) of replantation within 30 minutes after injury was higher than those within 30min-2h (68.89%) and 2h (37.14%) after injury. The success rate of tooth stored in milk (93.02%) was higher than that stored in physiological saline (70.00%), kept in patients’ oral (68.18%), and stored in dry medium (34.38%, P<0.05). Conclusion: The best prognosis could be achieved by performing the replantation within 30min after tooth dislocation. The success rate of tooth replantation could be improved by keeping the tooth in milk after the trauma. The success rate of replantation of undeveloped teeth was higher.
