摘要
本研究的目的是比较两种旋转再治疗系统在根管再治疗过程中清除填充物残留物的效果。材料和方法。20根下前磨牙根管采用ProTaper塑形,其次是F2和0.06锥度,并用杜仲胶冷侧凝填充。按再处理方式分为2组(n=10)。根据残余材料面积的评分,比较再治疗的次数和再治疗的放射学质量。结果。reproc系统(VDW GmbH, m nchen, Germany),每条运河的再处理时间为5.75秒,90%的运河在运河壁上的残留物少于20%。ProTaper再处理系统(Dentsply - Sirona, Switzerland)的再处理时间为7.15秒,60%的管道残留物少于20%。结论。在本研究的限制下,Reciproc系统被证明比ProTaper Retreatment系统更快、更有效。
Root canal retreatment using Reciproc and ProTaper universal systems. Comparative evaluation
The aim of this study was to compare the efficacy of two rotary retreatment systems in removing remnants of filling materials during root canal retreatment. Materials and methods. 20 lower premolar canals were shaped by ProTaper next up to F2 and .06 taper and filled using cold lateral condensation of gutta-percha. These were divided into 2 groups (n=10) according to the retreatment systems. There were compared the times of retreatment and the radiographic quality of retreatment based on scores attributed to areas of residual material. Results. Reciproc system (VDW GmbH, München, Germany) led to a medium retreatment time of 5.75 seconds per canal and 90% of the canals showed less than 20% remnants on the canal wall. ProTaper retreatment system (Dentsply – Sirona, Switzerland) led to a medium retreatment time of 7.15 seconds and 60% of the canals showed less than 20% remnants. Conclusion. Within the limitation of this study, Reciproc system proved to be more rapid and efficient than ProTaper Retreatment system.
