目的:观察氢氧化钙糊剂作为根管消毒药物的效果。方法:对162颗慢性根尖炎的患牙做常规根管处理后,分别选用氢氧化钙糊剂、甲醛甲酚(FC)棉捻消毒根管,并与封干棉捻的对照组比较效果。结果:氢氧化钙糊剂组优良率94.44%,FC组优良率79.63%,2组差异无显著性,但均显著高于干棉捻对照组的61.11%,而FC组部分患者有不良反应。结论:氢氧化钙糊剂是一种安全有效的根管消毒剂,可广泛用于临床。
Objective: To observe the effect of calcium hydroxide paste as root canal disinfectant. Methods: Totally 162 root canal disease patients with chronic apical inflammation were treated with conventional root canal treatment. Hydroxide paste and formaldehyde cresol were respectively used to sterilize the root canal. . Results: The excellent and good rate of calcium hydroxide paste group was 94.44%, the excellent and good rate of FC group was 79.63%. There was no significant difference between the two groups, but it was significantly higher than 61.11% of the dry cotton twisting control group, but some patients in the FC group had adverse reactions.
