摘要
目的观察用3种根管封闭剂充填根管后短期疼痛的发生情况。方法将明确诊断为牙髓炎和根尖炎需要行根管治疗的恒牙404颗随机分为3组,A组以碘仿氧化锌丁香油为封闭剂,B组以氧化锌丁香油为封闭剂,C组以Cortisomol为封闭剂,分别加牙胶尖进行根管充填,对术后24~72h疼痛发生情况用VAS评价标尺记录并用χ2检验分析比较。结果经统计学检验3组术后疼痛发生率有显著性差异(P<0.01),Cortisomol组术后反应最轻,碘仿氧化锌丁香油组术后反应最严重。结论以Cortisomol为封闭剂进行根管充填可明显减少术后疼痛。
Objective To compare the occurrence of postoperative pain after applying three different root canal sealers in root canal treatment.Methods A total of 404 teeth were randomly divided into three groups: group A using Zinc Oxide engenol(ZOE), group B using ZOE+iodoform and group C using Cortisomol sealer. The occurrence of postoperative pain was evaluated clinically 24-72 h after root filling.Results The difference in pain among the three groups were statistically significant after treatment. The group C caused minimum irritation and least pain among the three groups. Group A showed the most severe reaction. Conclusion The root canal therapy using Cortisomol sealer can significantly reduce pain.
