目的:探讨MTA、Vitapex、Metapex在年轻恒牙根尖诱导的临床应用效果。方法:选择延边大学附属医院口腔科2011年5月~2012年5月就诊的牙根未发育完成的70例上颌前牙年轻恒牙冠折露髓患儿共计90颗患牙,将其分为A、B、C组,分别使用MTA、vitapex、Metapex进行根尖诱导,后行完善的根管治疗。结果:1~2年治疗结束,MTA组成功率为98%,vitapex组为94%,Metapex组为90%,三者都具有良好的治疗效果。结论:在年轻恒牙根尖诱导中MTA的效果优于vitepex、Metepex,为理想的根尖诱导材料。
Objective: To investigate the clinical effect of MTA, Vitapex and Metapex on the induction of root tips of young permanent teeth. Methods: Seventy patients with undeveloped roots of 70 cases with maxillary anterior teeth who were diagnosed as having dental root failure from May 2011 to May 2012 in our hospital were divided into A , B, C group, respectively, using MTA, vitapex, Metapex root tip induction, followed by a sound root canal therapy. Results: After 1 to 2 years of treatment, the success rate of MTA group was 98%, vitapex group was 94%, Metapex group was 90%, all three had good therapeutic effect. CONCLUSION: MTA is superior to vitepex and Metepex in root tip induction of young permanent teeth, which is an ideal root tip inducing material.
