Apexit Plus糊剂用于感染根管一次性根充术后疗效观察

目的：对应用Apexit Plus糊剂一次性充填感染根管术后反应和1年后的临床疗效进行观察评价。方法：选择2012年2月-2013年2月来本院门诊就诊的慢性牙髓炎、慢性根尖周炎患者132例共140颗患牙。按随机数字表法分为试验组和对照组，每组各70颗患牙。两组均进行常规的根管充填术治疗，试验组使用Apexit Plus糊剂根管充填，对照组使用氧化锌碘仿丁香油糊剂根管充填。术后1周电话回访，1年后复诊进行临床检查，拍X线片，评价疗效。结果：试验组术后不良反应发生率明显低于对照组，差异有统计学意义（P〈0.05）。两组术后1年的疗效比较差异无统计学意义（P〉0.05）。结论：Apexit Plus糊剂一次性充填感染根管术后不良反应较低，1年后的临床效果与氧化锌碘仿丁香油糊剂术后结果近似，但远期临床治疗效果还有待进一步观察。

Clinical Observation of the Effect of Apexit Plus Sealer on Infected Root Canal Therapy of Disposable

Objective：To observe and evaluate the clinical effect of postoperative reaction of the Apexit Plus sealer used for infected root canal therapy of disposable after one year.Method：132 patients（140 tooth）who suffered from chronic pulpitis or chronic apical periodontitis in our hospital from February 2012 to February 2013 were chose. They were randomly divided into the experimental group（70 tooth）and the control group（70 tooth）. Both of the two groups were used the routine treatment of root canal fitting,the experimental group used Apexit Plus paste root canal,the control group used zinc oxide iodoform clove oil paste root canal. The telephone interview for the patients after a week,follow-up clinical examination was evaluated after 1 year and the curative effect evaluated by X-ray.Result：The incidence rate of postoperative reaction in the experimental group was significantly lower than the control group（P〈0.05）. Postoperative 1 years,the curative effect of two groups was compared,the difference was no statistical significance（P〉0.05）. Conclusion：The incidence rate of postoperative reaction with Apexit Plus sealer is lower,and the clinical effect is similar to iodoform zinc oxide-eugenol sealer. However,the long-term clinical efficacy remains to be seen.
