自固化磷酸钙治疗根尖周病的临床研究

A Clinical Study of Treatment of Periapecitis with Self-setting Calcium Phosphate

目的 寻求有效的充填根管及修复髓室底穿孔的材料。方法 将需要治疗的 2 88颗患牙随机分为实验组 15 6颗 (其中 18颗见髓室底穿孔 ) ,对照组 132颗。实验组用自固化磷酸钙糊剂充填根管 ,对照组用传统的酚醛糊剂加牙胶尖充填根管。结果 实验组有效率 96 .79% ,对照组 89.39%。经统计学检验 ,两组差异有显著性 (P <0 .0 5 )。髓室底穿孔修复率 83.33%。结论 自固化磷酸钙能有效地控制感染 。

Objective To explore an effective method for root canal filling and repairing perforation of pulp bottom. Methods 288 teeth were divided into two groups. The experimental group with 156 teeth were filled with paste of self-setting calcium phosphate,while the control group with 132 teeth were filled with traditional materials. Results The effective rate of the experiment group was 96.79%, while that of the control group was 89.39%. The statistical test showed that there was a singificant difference between the two groups (P<0.05).The effective rate of repairing perforation of pulp bottom was 83.33%. Conclusion It was considered to be a suitable material for root canal and repairing perforation of pulp bottom.
