【摘要】 目的观察常温流动牙胶充填根管的临床疗效。方法选择101例首次需要进行根管治疗的慢性根尖周炎患者,共计128颗磨牙,随机分成2组。采用旋转镍钛锉预备根管,A组66颗磨牙,用常温流动牙胶加牙胶尖根管充填;B组62颗磨牙,碧兰糊剂加牙胶尖进行根管充填。观察术后1年患者的临床疗效和X线片的根周影像,评价近期疗效。结果术后1年共复诊83例(91颗牙);A组50例(55颗牙);B组33例(36颗牙)。A组4例(7.27%)、B组1例(2.78%)有临床症状;2组X线片各有3例(5.45%)出现根周膜间隙增宽和2例(5.56%)根尖病变未愈。2组术后临床成功率无显著性差异(P>0.05)。结论常温流动牙胶与碧兰糊剂一样对根管具有良好的封闭能力,可作为根管充填材料使用,远期疗效还有待进一步观察。更多还原

【Abstract】 Objective To evaluate the outcome of root canal treatment (RCT) using GuttaFlow with lateral condensation (LC) technique.Methods A total of 101 patients(128 molars)who required primary and nonsurgical RCT were included.They were randomly divided into 2 groups.The root canals were instrumented and finally filled with either Gutta-Flow (group A,66 molars) or Cortisomol (group B 62 molars) by gutta-percha lateral compact technique.The treated teeth were examined both clinically and radiographically one years after the treatment by the same examiner.Results The one year follow-up was completed in 83 patients(91 teeth),including 55 teeth filled with GuttaFlow and 36 teeth with Cortisomol.Post-treatment symptoms were observed in four teeth (7.27%) of the GuttaFlow group and in one teeth (2.78%) in the Cortisomol group,while the radiographic radiolucency were found in three teeth (5.45%) of the GuttaFlow group and in two teeth (5.66%) in the Cortisomol group.There was no significant difference in success rate between the two groups(P > 0.05).Conclusion GuttaFlow is as good as Cortisomol in root canal filling and can be used for root canal treatment,but the long term clinical results need further investigation.更多还原
