Clinical curative effect comparison of three kinds of root canal disinfection medicines

目的:比较氢氧化钙、抗生素制剂和甲醛甲酚在根管内的消毒效果。方法:选取慢性根尖周炎的单根管牙576颗,经常规扩根管冲洗后,192颗牙在根管内封入氢氧化钙,192颗根管内封抗生素制剂,192颗根管内封甲醛甲酚,观察封药前后临床症状和体征的变化以及根管充填12个月后的治疗效果。结果:3组封药后,氢氧化钙组对自发痛、叩痛、瘘管、根管渗液的疗效明显优于抗生素制剂组、甲醛甲酚组(P<0.05)。结论:氢氧化钙较其他消毒剂效果好,是根管治疗理想的消毒剂。

Objective:To compare the disinfection effects of calcium hydroxide,antibiotics preparation and formaldehyde cresol in root canal.Methods:576 single root canal teeth of chronic periapical periodontitis were selected.After conventional root canal irrigation,192 teeth were enclosed calcium hydroxide in root canal,192 teeth were enclosed antibiotics preparation in root canal,192 teeth were enclosed formaldehyde cresol in root canal.The changes of clinical symptoms and signs before and after sealing medicine and the treatment effects after root canal filling 12 months were observed.Results:After sealing medicine of three groups,the curative effects on the spontaneous pain,knocking pain,fistula,root canal seepage of the calcium hydroxide group were obviously better than those of the antibiotics preparation group and formaldehyde cresol group(P<0.05).Conclusion:The effect of calcium hydroxide is better than other disinfectants.It is the ideal disinfectant in root canal therapy.
