OBJECTIVE
The aim of this study was to evaluate the cleaning effectiveness achieved with two reciprocating single-file systems in severely curved root canals: Reciproc and WaveOne.
MATERIALS AND METHODS
Twenty-five mesial roots of mandibular molars were randomly separated into two groups, according to the instrumentation system used. The negative control group consisted of five specimens that were not instrumented. The mesial canals (buccal and lingual) in Reciproc Group were instrumented with file R25 and the WaveOne group with the Primary file. The samples were submitted to histological processing and analyzed under a digital microscope.
RESULTS
The WaveOne group presented a larger amount of debris than the Reciproc Group, however, without statistically significant difference (P > 0.05). A larger amount of debris in the control group was observed, with statistically significant difference to Reciproc and WaveOne groups (P < 0.05).
CONCLUSIONS
The two reciprocating single-file instrumentation systems presented similar effectiveness for root canal cleaning.
目的
本研究旨在评估两种往复式单根管系统在严重弯曲根管中的清洁效果：Reciproc和WaveOne。
材料与方法
根据所使用的器械系统，将25颗下颌磨牙的近中根随机分为两组。阴性对照组由5个未进行器械操作的标本组成。Reciproc组的近中根管（颊侧和舌侧）用R25锉进行器械操作，WaveOne组用初尖锉进行操作。样本进行组织学处理，并在数字显微镜下分析。
结果
WaveOne组的碎屑量比Reciproc组多，但无统计学显著差异（P>0.05）。观察到对照组的碎屑量更多，与Reciproc组和WaveOne组有统计学显著差异（P<0.05）。
结论
两种往复式单根管器械系统在根管清洁方面表现出相似的效果。
