两种根管充填糊剂一次性根管治疗术后疼痛和疗效观察

目的：比较两种根管充填糊荆治疗的一次性根管治疗术后疼痛和临床疗效。方法：103颗需根管治疗的患牙随机分为2组，分别采用Cortisomol糊剂和碘仿氧化锌丁香油水门汀、以及牙胶尖，冷侧压法一次性充填根管。观察术后1周内疼痛的VAS评分和1年后的临床疗效。结果：Cortisomol组2天的VAS评分显著低于碘仿氧化锌丁香油组（P〈0．01），7天时差异无显著性（P〉0．05）。术后一年复查，Cortisomol组疗效好于氧化锌组，两组之间差异无显著性（P〉0．05）。结论：Cortisomol糊剂充填根管，可以有效减少一次性根管充填术后急性期疼痛的发生。

Postobturation pain and therapeutic effects of Cortisomol sealer and zinc oxide eugonol added iodoform in single-visit root canal therapy

Objective: To compare the postobturation of pain and the therapeutic effects of Cortisomol sealer and zinc oxide eugonol added iodoform in single-visit root canal therapy. Methods: 103 teeth were randomly divided into 2 groups. All teeth were treated with root canal therapy in single-visit. Cortisomol sealer and zinc oxide eugonol plus iodoform were used respectively in treatment. The pain intensity within 1 week after treatment was evaluated by visual analogue scale. The therapeutic effects were evaluated by follow up of 12 months. Results: The pain intensity of the former group were not significantly lower than that of the latter group in 7 d (P > 0.05), but in 2 d (P < 0.01). After 12 months, efficiency rate of the former group was higher than that of the latter group without significant difference (P > 0.05). Conclusion: Root canal therapy using Cortisomol sealer can significantly decrease postoperative pain.
