氢氧化钙制剂在根管治疗中的临床应用

Calcium hydroxide paste for root canal therapy

目的观察氢氧化钙制剂在根管治疗中的临床应用效果。方法将250例急、慢性根尖周炎患牙随机分为实验组和对照组,实验组采用氢氧化钙糊剂进行根管治疗;对照组采用甲醛甲酚液进行治疗。观察根管治疗暂封1周后临床疗效对比情况。结果实验组疗效优的比率为88.8%,而对照组则为38.4%,差异有显著性(P<0.01)。暂封一次即可根充者实验组104例(83.2%),对照组64例(51.2%)。结论采用氢氧化钙糊剂作为根管内封药,能够减少甲醛甲酚所带来的不良反应,达到满意的疗效。

Objective To analyse clinical therapeutic effects of root canal filled by calcium hydroxide paste. Methods 250 cases suffering acute or chronic periapical periodontitis were randomly divided into trial group and control group. The root canals in trial group were filled with calcium hydroxide paste and those in the control group were treated with formaldehyde cresol formocresol （FC） liquid. Results After one week of root canal therapy （RCT）,the curative rate of trial group was 88.8%, superior to that of control group（38.4%）. There was statistically significant difference between the two groups （P〈0.01）. After temporary sealing for only once,104 cases in trial group could be treated by root canal filling （83. 2%）, while only 64 cases could in control group （51. 2%）. Conclusion Calcium hydroxide paste as root canal filling materials can preclude the adverse effects arising from the application of FC and will achieve a satisfactory clinical therapeutic effect.
