摘要
目的:评价不锈钢K锉、机用ProTaper和机用Safe Sider预备磨牙弯曲根管的临床疗效。方法:选取因牙髓炎或根尖周炎需要进行根管治疗的磨牙180颗(413个根管),随机分为K-file组、ProTaper组和Safe Sider组,每组60颗牙。分别用不锈钢K锉、机用ProTaper和机用Safe Sider进行根管预备。三组均采用冷牙胶侧方加压技术充填根管。记录三组病例根管预备时间和术后并发症发生情况,根据治疗前、中、后的X线片评价根管预备和充填效果。结果:机用ProTaper、机用Safe Sider分别与不锈钢K锉在根管预备时间、根管成形以及充填效果方面在统计学上有显著性差异(P﹤0.05),机用ProTaper与机用Safe Sider在上述方面无显著性差异(P﹥0.05)。结论:机用ProTaper和机用Safe Sider预备磨牙弯曲根管时能较好地保持原有根管形态,省时省力,术后反应少。
Objective:To evaluate the clinical effect of K-file、ProTaper and SafeSider in preparation of curved molar root canals.Method:A total of 180 teeth which needed endodontic treatment were selected and randomly divided into 3 groups with 60 teeth in each group:K-file group、ProTaper group and SafeSider group.The root canals were prepared with 3 instruments respectively.All canals were obturated using lateral condensation technique.The efficacy of canal preparation and obturation by X-ray before,during and after operation was analyzed.Result:Statistically significant difference was found in mean working time,shaping curved molar canals and exact root canal obturation between K-file group、ProTaper group or SafeSider group.No Statistically significant difference was found in mean working time,shaping curved molar canals and exact root canal obturation between ProTaper group and SafeSider group.Conclusion:ProTaper and SafeSider tested in this study are effective and time-saving in shaping curved molar canals,it also caused less post-operative pain.The results indicated both ProTaper and SafeSider were comparable to optimally enlarge root canal.
