三种根管封闭剂应用于根管一次法的临床疗效比较

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

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7d及6个月的临床疗效。结果:三组术后7d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7d临床反应最小。

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.
