三种根管封闭剂应用于根管一次法的临床疗效比较

目的:观察三种永久性根管充填糊剂,即:氧化锌加丁香油(A组)、氧化锌、丁香油加碘仿(B组)、法国碧兰CORTISOMOL加丁香油(C组)加牙胶尖,在根管充填一次法治疗慢性根尖炎中应用的近期疗效.方法:将经临床及X线确定的246颗慢性根尖炎的患牙随机分成三组,分别用三种不同的糊剂充填,再加入牙胶尖,观察其术后7 d及6个月的临床疗效.结果:三组术后7 d的临床疗效相比均有显著性差异(P<0.05),其中以法国碧兰CORTISOMOL组疗效最佳,术后反应最小;其次为碘仿氧化锌组;术后反应最大的为氧化锌丁香油组.三组术后6个月的临床疗效相比均无显著性统计学差异(P>0.05) .结论:法国碧兰CORTISOMOL 永久性充填材料在根管治疗一次法术后7 d临床反应最小.

The clinical effect of three kinds of permanent root canal filling material on one visit root canal therapy

To assess the treatment results of one visit root canal therapy for chronic periapical inflammation using three kinds of permanent sealing paste and gutta-percha at 7 days and 6 months. Methods: A total of 246 teeth with chronic periapical inflammation were randomly divided into three groups. Group A using ZOE ( Zinc Oxide-euge-nol) , group B using ZOE iodoform and group C using CORTISOMOL. Immediate root canal filling was taken in all teeth. Treatment results were evaluated clinically and radiographically 7 days and 6 months after ward. Results: The differences among three groups were statistically significant 7 days after treat ment(P<0. 05). The curative effect of group C was the best with minimum irritation among three groups. Group A showed maximum reaction. By statistics, it was no difference for the overall healing rates among groups after 6 months (P >0. 05). Conclusion:The short-term curative effects of one visit root canal therapy using CORTISOMOL sealing paste is better than that using other two kinds of sealing paste within 7 days.
