The present in vitro study aimed to compare the effectiveness of the WaveOne and ProTaper Gold systems in removing the biofilm. Thirty-eight mandibular premolars were selected. The root canals were assigned to standard control (canals serially enlarged with ProTaper Gold S1-S2-F1-F2, n=15) and experimental (canals enlarged with Primary WaveOne file, n=15) groups. Following the instrumentation procedure, the root canals underwent a sampling procedure, and the colonyforming unit (CFU) counts were determined. The samples were also evaluated under a fluorescent microscope to evaluate viable bacteria. The data were analyzed using independent samples t test and paired samples test. The results showed that, compared with the ProTaper group, the WaveOne group exhibited the least viable bacteria ( =0.004). It was concluded that comparison with the ProTaper Gold rotary system, the WaveOne reciprocating file is more successful in reducing intratubular viable bacteria counts.
本体外研究旨在比较WaveOne系统和ProTaper Gold系统在清除生物膜方面的有效性。选取了38颗下颌前磨牙。将根管分为标准对照组（用ProTaper Gold S1-S2-F1-F2依次扩大根管，n = 15）和实验组（用WaveOne初尖锉扩大根管，n = 15）。在进行根管预备后，对根管进行采样，并测定菌落形成单位（CFU）计数。还在荧光显微镜下对样本进行评估以评估活菌。使用独立样本t检验和配对样本检验对数据进行分析。结果显示，与ProTaper组相比，WaveOne组的活菌最少（P = 0.004）。得出的结论是，与ProTaper Gold旋转系统相比，WaveOne往复锉在减少根管内活菌计数方面更成功。
