氢氧化钙糊剂用于治疗约诊间疼痛的临床观察

Clinical observation of using calcium hydroxide to control the EIAP

目的观察氢氧化钙在治疗约诊间疼痛中的临床疗效。方法临床诊断为牙髓炎及根尖周炎治疗期间出现疼痛的病例共386例,随机分成试验组(氢氧化钙组)与对照组(樟脑酚+碘仿),各193例。根管内封入材料,观察封药后疼痛症状是否消除。结果试验组中治疗轻、中度约诊间疼痛患者的成功率分别为92.8%和94.4%明显优于对照组的82.3%和65.2%(P<0.01)。两组重度疼痛患者的疗效无统计学差异(P>0.05)。结论氢氧化钙糊剂是较理想的根管消毒剂,治疗轻、中度约诊间疼痛有较好的效果。

Objective To evaluate clinical effect of calcium hydroxide in controlling the EIAP. Methods 386 cases, which were diagnosed as pulpitis and periapieal periodontitis with EIAP were selected. They were randomly divided into experimental group（ calci- um hydroxide） and control group（ camphor phenol ＋ iodoform） with 193 cases in each group. The materials were inserted into the ca- nal root and then to observe whether the EIAP was eliminated after using material in root canal. Results The success rate of mild and moderate cases in experimental group was 92.8% and 94.4% respectively, significantly better than the 82.3% and 65.2% in the control group（ P 〈 0.01 ）. There were no differences between the groups of patients with severe pain（ P 〉 0.05 ）. Conclusions Calci- um hydroxide paste is an ideal root canal disinfectant, which can control the EIAP effectively.
