目的观察Cortisomol糊剂和氧化锌碘仿糊剂在根管治疗术后的反应及远期疗效。方法将门诊须作根管治疗的229个牙随机分为:Cortisomol糊剂组114个牙,氧化锌碘仿糊剂115个牙。常规根管预备后,两组分别用Cortisomol糊剂加牙胶尖根充和氧化锌碘仿糊剂加牙胶尖根充。结果根充1周后Cortisomol糊剂组术后反应率明显低于氧化锌碘仿糊剂组(P<0.05),远期治疗两组无明显差异(P>0.05)。结论 Cortisomol糊剂用于根管治疗术后反应轻、疗效可靠。
Objective To observe the response and long-term efficacy of Cortisomol paste and zinc oxide iodoform paste after root canal therapy. Methods The 229 teeth to be treated as root canal for outpatient treatment were randomly divided into 114 teeth of Cortisomol paste group and 115 teeth of zinc oxide iodoform paste. After conventional root canal preparation, the two groups were treated with Cortisomol paste plus gingival root tip and zinc oxide iodoform paste plus gingival root tip filling. Results The postoperative response rate of Cortisomol paste group was significantly lower than that of zinc oxide iodoform paste group (P <0.05) after one week of root filling. No significant difference was found between the two groups (P> 0.05). Conclusions Cortisomol paste is light and effective in postoperative root canal therapy.
