目的观察Vitapex糊剂一次法根管治疗牙髓病、慢性根尖周病的疗效。方法将2006-2008年来我科就诊牙髓病、慢性根尖周病患者184例(190颗患牙)随机分为试验组93例(96颗患牙)和对照组91例(94颗患牙),分别应用Vitapex糊剂一次法根管充填和常规根管充填糊剂加牙胶尖侧方加压充填。观察术后1周、12个月的临床反应及疗效。结果术后1周试验组89颗患牙无疼痛,对照组62颗患牙无疼痛,分别为92.71%和65.96%,差异有统计学意义(p<0.01);术后12个月试验组有93颗患牙成功,成功率为96.88%,对照组有71颗患牙成功,成功率为75.53%,差异有统计学意义(p<0.01)。结论 Vitapex糊剂在一次法根管治疗牙髓病、慢性根尖周病中具有较好的疗效,是一次法根管治疗的理想填充材料。

Objective To observe the therapeutic effect of onetime root canal therapy with vitapex paste in the treatment of pulpitis and chronic periapical periodontitis. Method 184 patients （190 diseased teeth） with pul- pitis and chronic periapical periodontitis in our department of dentistry from 2006 to 2008 were randomly divid- ed into experimental group with 93 cases （96 diseased teeth） and control group with 91 cases （94 diseased teeth）, and were treated with one-time root canal compaction with vitapex paste and with regular root canal compaction paste and lateral condensed gutta percha respectively. The clinical responses and therapeutic effect were observed one week and twelve months after the surgery respectively. Results One week after the surger- y, 89 diseased teeth in the experimental group felt no pains and 62 diseased teeth in the control group felt no pains, which accounted for 92.71% and 65. 96% of each group respectively, and the differences were statisti cally significant （P〈0.01）; Twelve months after the surgery, 93 diseased teeth in the experimental group were cured with a success rate of 96.88% and 71 diseased teeth in the control group were cured with a success rate of 75.53%, and the differences were statistically significant （P〈0.01）. Conclusion Vitapex paste has relatively good therapeutic effects in one-time root canal therapy for treating pulpitis and chronic periapical pe riodontitis and thus it is an ideal root canal sealer material for the one-time root canal therapy.
