Evaluation of Cleaning Efficacy of S-One and WaveOne File Systems Using Scanning Electron Microscopy Analysis: An In...

The aim of this study is to compare the canal cleaning ability of S-One file (AF BLUE) system with WaveOne Gold single file system, using scanning electron microscopy (SEM).

In the present study, 40 freshly extracted permanent mandibular premolars with a single-root canal and straight roots were selected. The teeth were randomly divided into three groups. The canals were prepared by crown-down technique. Buccolingual sectioning of the samples were done followed by SEM evaluation. Data were statistically analyzed using Kruskal-Wallis test. The statistical significance level was set at p value <0.05.

The analysis of the results demonstrated that WaveOne presented higher cleaning capacity of root canals with a statistically significant difference, when compared to S-One file system (p value < 0.05). Both the file systems showed significant cleaning efficacy in the coronal and middle-thirds of the root canals when compared to the apical thirds. Also, the WaveOne showed better results than S-One (AF BLUE), and the results were statistically significant.

With the limitation of the study, the cleaning ability of rotary file system is high in coronal and middle-third followed by apical third. In this study, the WaveOne showed better results than S-One (AF BLUE), and the results were statistically significant.

The aggressive cutting of dentin during canal preparation is less in WaveOne file than S-One file system. The cleaning efficiency is good in reciprocating file system (WaveOne) than continuous rotary file system (S-One).
