Abstract:

INTRODUCTION AND OBJECTIVE: Study the apical debris extraction in the channels expanded with different rotating curve systems and determine the effect of landing METHODS and OBJECTIVES: Doksan six curved root channels; Twisted File Adaptive, WaveOne, ProTaper Next and MTwo systems expanded. Each group was divided into two subgroups, the lower and the upper neck groups, and a experimental arrangement used to imitate the lower and the upper neck. The amount of stone debris was measured with a sensitive tint at 10-5 sensitivity. NOTE: There was no significant impact on the amount of debris that stumbled from the apical on the curved systems of the tooth positions (p> 0, 05). However, when it was assessed independently of the curves, it was observed that there were more debris in the lower neck position (p< 0, 05). RELATED AND RESULTATED: In all curved systems, a certain amount of debris was seen from the apical. The influence of curvation systems and landing on the stone debris from the apical was not observed.
