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 hydrox-yapatite 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 con-trol 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.
