The aim was to evaluate debris and smear layer at 1, 3 and 5 mm from the foramen of single-file systems WaveOne Gold® and Reciproc Blue®. Thirty single-rooted teeth were prepared using one of the following NiTi instruments WaveOne Gold® and Reciproc Blue®. Root canals were observed under a scanning electron microscope. The presence of debris and smear layer at the apical third of root canals was evaluated. Data were analysed by Friedman and Wilcoxon tests. WaveOne Gold® produced significantly less debris and smear layer compared to Reciproc Blue®. However, the mean amount of debris was significantly different within distances for WaveOne Gold®, while no difference were observed for Reciproc Blue. The mean amount of smear layer was not significantly different within distances with WaveOne Gold® and Reciproc Blue®. Both systems showed debris and smear layer in the apical third; nevertheless, WaveOne Gold® showed better results.
目的是评估单支锉系统WaveOne Gold®和Reciproc Blue®距根尖孔1、3和5毫米处的碎屑和玷污层。使用以下镍钛器械之一WaveOne Gold®和Reciproc Blue®对30颗单根牙进行预备。在扫描电子显微镜下观察根管。评估根管根尖三分之一处碎屑和玷污层的存在情况。数据采用Friedman和Wilcoxon检验进行分析。与Reciproc Blue®相比，WaveOne Gold®产生的碎屑和玷污层明显更少。然而，WaveOne Gold®在不同距离处的碎屑平均量有显著差异，而Reciproc Blue®则未观察到差异。WaveOne Gold®和Reciproc Blue®在不同距离处的玷污层平均量无显著差异。两种系统在根尖三分之一处均显示有碎屑和玷污层；尽管如此，WaveOne Gold®显示出更好的结果。
