摘要
目的观察Protaper手用镍钛锉预备乳磨牙根管的临床疗效。方法选择4～8岁需做根管治疗的患儿160例,乳磨牙160颗,随机分为Protaper手用镍钛锉冠向下法备根组80颗,手用不锈钢K锉逐步后退法备根组80颗,均用注射型Metapex糊剂根充,术后即刻拍片评价根充成功率,术后3 d回访评价疼痛率。结果 Protaper组疼痛率3.75%,不锈钢K锉组疼痛率15.00%(P<0.05),差异有统计学意义。Protaper组成功率95%,不锈钢K锉组成功率83.75%(P<0.05),差异有统计学意义。结论 Protaper手用镍钛锉预备乳磨牙根管疼痛反应轻,快捷高效,临床疗效优于手用不锈钢K锉,值得临床推广。
Objective To observe the clinical efficacy of preparation of primary molars root canals with Protaper hand Niti file.Methods Select dental outpatients aged 4-8 years old who visited our department between 2010.1-2012.2,160 primary molars which needed root canal treatment were randomly divided into two groups.80 of them were prepared with Protaper hand Niti file crown-down the root,and the other 80 teeth were prepared with stainless steel K-file step by retreating preparation of the root canals.Metapex paste was injected into root canals,and immediately films were taken to evaluate the success rates of root canals.Assess pain rates in the return visit three days after the treatment.Results Pain rate of Protaper group was 3.75%,while pain rate of stainless steel K-file group was 15%,P＆lt;0.05,and there was significant difference.Success rate of the Protaper group was 95%,while success rate of stainless steel K-file group was 83.75%,P＆lt;0.05,and there was significant difference.Conclusions It is fast and efficient to use Protaper hand NiTi file in preparation of primary molars.Its tube pain response is light,and Its clinical efficacy is better than that of hand stainless steel K-file.So it′s worthy of promotion.
