【摘要】 目的观察Cortisomol糊剂和Vitapex糊剂用于磨牙慢性根尖周炎的一次性根管治疗术后的反应及远期疗效。方法选择慢性根尖周炎需做根管治疗的磨牙107颗,随机分成A、B二组,分别以Cortisomol糊剂和Vitapex糊剂加牙胶尖进行根充,并对二组术后1～7d、1年的临床疗效进行比较分析。结果治疗后1～7dA组术后反应率较B组要低(P<0.05),远期疗效两组无明显差异(P>0.05)。结论 Cortisomol糊剂用于一次性根管治疗术后反应较少,且疗效可靠。更多还原

【Abstract】 Objective To study the postoperative response and long-term efficacy of Cortisomol and Vitapex paste on chronic periapical periodontitis after one-off root canal filling therapy. Methods Patients who suffered chronic periapical periodontitis and required root canal filling therapy were recruited and randomized into two groups,A and B.107 ill Molars in two groups were filled with either Cortisomol paste or Vitapex paste plus gutta-percha.1-to-7-days and 1-year efficacies of root canal filling therapy in two groups were compared and analyzed.Results The 1-to-7-day postoperative response to root canal filling therapy with Cortisomol paste in group A was clear than that in group B filled with Vitapex paste(P< 0.05). 1-year long-term efficacy of root canal filling therapy showed no significant difference between two groups(P> 0.05). Conclusions Cortisomol paste showed less postoperative response and better efficacy after one-off root canal filling therapy.更多还原
