Dent Mater J:GuttaCore Pink, Thermafil和热垂直加压牙胶的再治疗

非手术治疗的目标是获得进入根管系统的通道以便去除之前的充填物。

非手术治疗的目标是获得进入根管系统的通道以便去除之前的充填物。

研究分析了45颗之前未行牙髓治疗、折裂、再吸收性损伤或根尖孔开放的人单根管牙根、下颌磨牙的近中根和上颌磨牙的远中根。研究评估使用了全新一代GuttaCore, GuttaCorePink®充填的根管通过ProTaper® Retreatment和ProTaper® Universal实施再治疗所需时间,并与Thermafil®和热垂直加压充填牙胶相比较。并且,在根管再治疗和成型后定量分析残留充填材料的量。采用Kruskal-Wallis和Dunn's检验进行统计学评估。

结果显示,与Thermafil®相比,GuttaCore Pink®被移出根管系统内所需时间更少。而对于残留充填材料的量而言,3组间无显著性差异。
