Özet
INTRODUCTION: The aim of this study was to evaluate the effect of the curvature on the amount of apically extruded debris caused by three NiTi systems using different kinematics via including straight and severely curved root canals.METHODS: 84 severely curved and 84 straight mature root canals were instrumented with; Twisted File Adaptive (TFA), ProTaper Next (PTN) and WaveOne Gold (WOG) systems.The extruded debris and irrigant was collected into pre weighed glass tubes and weighed by using a 10-5 microbalance after the evaporation of irrigant.The effect of curvature on debris extrusion were analysed with t test and the amount of debris extrusion between the file systems was compared with One-way ANOVA test at a 0.05 level of significance.RESULTS: Within each file system, the amount of extruded debris was similar for curved and straight canals (p > 0.05).The tested instruments showed no significant differences in amount of extruded debris for both straight and curved root canals (p > 0.05), with the following ranking order: PTN > WOG > TFA. DISCUSSION AND CONCLUSION: It can be concluded that all the tested instruments with different kinematics caused debris extrusion and the curvature of the root canal has no effect on apical debris extrusion.
