自固化磷酸钙应用于根尖屏障形成的临床观察

Self-eeting Calciun Phosphate Cement as Apical Barrier in Hunan Teeth

目的探讨自固化磷酸钙在根尖屏障形成中的疗效。方法选择门诊牙根发育停止的患牙79颗,随机分为自固化磷酸钙组和氢氧化钙组,诱导根尖形成,观察2组根尖屏障形成的效果。结果治疗后第3年复诊,自固化磷酸钙组95%的患牙根尖屏障形成,硬组织封闭根端,氢氧化钙组71%的患牙根尖屏障形成封闭根端,2组间差异有统计学意义(P<0.05)。结论自固化磷酸钙应用于根尖屏障形成可获得较好的效果。

Objective To evaluate the cilinical results of treatment of teeth with open apices using self-seeting ealciun phosphate cement （CPC） as apical barrier. Methods Sevety-nine teeth with unfinished root development were collected in patients, and then they were randomly divided into two groups. One group was treated with CPC and another was treated with calcium hydroxide. Results The rate of successful forming of apical barrier in CPC group was 95%, compared to 71% in the group using calcium hydroxide. There was significant difference between two groups （P〈0.05）. Conclusion Application of CPC in complicated apical barrier can get satisfactory result.
