玻璃纤维桩在年轻恒牙冠折修复中的临床应用

Clinical application of glass fiber post in repair of young permanent teeth after traumatic dental injury

目的:探讨玻璃纤维桩在年轻恒牙冠折修复中的临床应用效果。方法:选择2007年6月～2009年6月在吉林大学口腔医院就诊的64例年轻恒牙冠折露髓的患儿,共计90颗患牙,拍摄X片观察牙根发育情况,对牙根未发育完全的60颗患牙先用活髓切断术或V itapex进行根尖诱导,待牙根形成后,行完善的根管治疗。将其分为实验组(A组)和对照组(B组),A组50颗行玻璃纤维桩树脂核冠修复,B组40颗行螺纹钉树脂桩核冠修复,定期复诊观察两组的临床应用效果。结果:1年后经玻璃纤维桩树脂核冠修复的50颗患牙中有48颗修复成功,成功率为96.0%。经螺纹钉树脂桩核冠修复的40颗患牙中有33颗修复成功,成功率为82.5%,两种方法修复成功率具有统计学差异(P<0.05)。结论:玻璃纤维桩在年轻恒牙冠折修复中效果理想,可以满足临床要求。

Objective：To explore the clinical application efficacy of glass fiber post in repair of young permanent teeth after traumatic dental injury.Methods：64 children with young permanent teeth after traumatic dental injury in stomatological hospital of Jilin university from June 2007 to June 2009 were selected,and 90 teeth with diseases were included in the study,X-ray tomography was used to observe the developmental situation of root of tooth,60 teeth with diseases and undeveloped root received vital pulpotomy and apexification by Vitapex;after the formation of root of tooth,perfect root canal therapy was carried out.The 90 teeth with diseases were divided into experimental group（group A） and control group（group B）,50 teeth in group A were treated with resin nuclear crown repair by glass fiber post,and 40 teeth in group B were treated with resin nuclear crown repair by threaded nail,the teeth in the two groups were followed up regularly,the clinical application efficacies of the two groups were observed.Results：After one year,among the 50 teeth treated with resin nuclear crown repair by glass fiber post,48 teeth were repaired successfully,the success rate was 96.0%.Among the 40 teeth treated with resin nuclear crown repair by threaded nail,33 teeth were repaired successfully,the success rate was 82.5%,there was significant difference between the two groups（P〈0.05）.Conclusion：The clinical efficacy of glass fiber post in repair of young permanent teeth after traumatic dental injury is ideal,and the method can satisfy the clinical demand.
