珊瑚羟基磷灰石骨粉充填根尖刮治术后骨腔的临床疗效观察

Coralline hydroxyapatatite bone filling bone cavities apical curettage clinical observation

目的：探讨珊瑚羟基磷灰石骨粉充填根尖刮治术后骨腔的临床疗效。方法：选取83颗根尖暗影超过1．0cm，瘘管久治不愈的患牙，行根尖刮治术后骨腔填塞珊瑚羟基磷灰石骨粉53颗牙，未行填塞的31颗牙作为对照，观察3~6个月及5年两组病例骨腔的愈合情况。结果：实验组53颗患牙治疗有效率达96．62％，对照组有效率仅为61．29％。差异有显著统计学意义（P〈0．01）。结论：珊瑚羟基磷灰石骨粉在治疗较大根尖破坏伴瘘管的患牙，具有良好的骨修复效果。

Objective： Explore the coralline hydroxyapatite bone filling bone cavities apical curettage clinical efficacy. Method： 83 apical shadow over 1.0 cm, fistula long lasting teeth, OK apical curettage of bone cavity filling coralline hydroxyapatite bone 53 teeth,31 teeth do not line tamponade as a control, and then observed for 3-6 months and 5 years of two groups of patients healing of the bone cavity. Result： The experimental group, 53 teeth treatment rate of 96.62 % in the control group was only 61.29 %. A significant difference （P 〈0.01）. Conclusion：Treatment of coralline hydroxyapatite larger apical long lasting damage to the teeth with fistula, with good results.
