Abstract Background The aim of this study was to compare the cleaning ability of rotary NiTi systems with different kinematics: ProTaper Next (PTN) (continuous rotation motion), WaveOne Gold (WOG) (reciprocating motion), and Twisted File Adaptive (TFA) (adaptive motion). Methodology Sixty mesiobuccal roots from extracted mandibular molars were divided into three groups (n = 20): PTN, prepared by ProTaper Next; WOG, prepared by WaveOne Gold system; and TFA, prepared by Twisted File Adaptive systems. Teeth were longitudinally split into two halves for evaluation by scanning electron microscope. Images were analysed for debris and smear layer scores using the scoring system described by Hülsmann et al. (J Endod 23:301–6, 1997). Results No significant difference was found between the three groups in the coronal one third (P = 0.071). However, the TFA group recorded a significantly higher percentage of debris in the middle and apical thirds (P |
