Vitapex糊剂一次性根充治疗乳牙慢性根尖周炎的临床观察

目的观察Vitapex糊剂一次性根充治疗乳牙慢性根尖周炎的临床疗效。方法选择162颗乳牙慢性根尖周炎患牙,随机分成治疗组和对照组,所有病例均常规去龋、制洞,揭髓顶并预备根管,治疗组使用注射器将Vitapex糊剂平稳充满根管,对照组用螺旋根管将调好的ZOE糊剂缓缓导入根管,随访1~2年观察两组临床效果。结果治疗组术后1周的反应率显著低于对照组（P〈0.05）;根充术后超充吸收率高于对照组（P〈0.01）;治疗成功率比较差异无统计学意义（P〉0.05）。结论 Vitapex糊剂一次性根充治疗乳牙慢性根尖周炎,反应率低,超充后吸收率高,是保存乳牙到乳、恒牙替换期的一种有效方法。

Clinical observation of Vitapex paste root canal one-time filling in the treatment of chronic periapical periodontitis of deciduous teeth

Objective To observe the therapeutic efficacy of Vitapex paste root canal one-time filling in the treatment of chronic periapical periodontitis of deciduous teeth.Methods 162 cases of periodontitis of deciduous teeth were randomly assigned to treatment group and control group.Procedures of conventional caries removal,cavity preparation,myeloid top exposure and root canal preparation were carried out in both groups.Root canal were filled with Vitapex paste stably using a syringe in the treatment group while in the control group root canal were filled with ZOE paste slowly using a spiral root canal.The clinical effects of the two groups were observed in the 1-2 years follow-up.Results The response rate after 1 week of the treatment group was significantly lower than that of the control group(P < 0.05);and overfilling absorption rate was also higher in the treatment group(P < 0.01);there were no significant difference between the two groups in treatment success rates(P > 0.05).Conclusion Vitapex paste root canal one-time filling has low response rate and high overfilling absorption rate in the treatment of chronic periapical periodontitis of deciduous teeth,thus is an effective way to reserve deciduous teeth till there were replaced by the permanent teeth.
