【摘要】 目的将两种临床常用材料氢氧化钙制剂(Vitapex)和碘仿制剂用于年轻恒牙的根尖诱导术,探讨提高根尖诱导成形术疗效的方法。方法选择患急、慢性牙髓炎及根尖周炎且根尖无病变的47颗年轻恒牙,进行常规的根管预备后,分成两组,Vitapex糊剂(22例)和碘仿糊剂(25例)行根尖诱导成形术,并对患者进行2年的随访观察疗效。结果碘仿糊剂组的成功率为64.0%,Vitapex糊剂组为81.8%。结论Vitapex糊剂用于年轻恒牙的根尖诱导术能取得良好效果。更多还原

【Abstract】 Objective To study the effectiveness of iodoform paste and Vitapex paste in apexification of young permanent teeth.Methods Fourty-seven young permanent teeth with acute/chronic pulpitis and apical peridontitis without previous treatment were selected.After access to the root canals and complete removal of the pulp,canal preparation was then carried out.The 47 young permanent teeth were assigned to either of two apexification groups: group A(n=25) with iodoform paste or group B(n=22) with Vitapex paste.All cases were reviewed up to 24 months.Results The use of iodform paste for apexification is successful in 64.0% of group A,and Vitapex paste in 81.8% of group B.Conclusion Vitapex paste has better effectivenes for apexification in young permanent teeth.更多还原
