Quantitative evaluation of the apically extruded debris from root canals prepared by single-file rotary and reciprocating file systems: An study.

Aim: The aim is to investigate and compare the amount of apically extruded debris after root canal preparation using single rotary and reciprocating file system.

Materials And Methods: Forty single-rooted human mandibular premolars with straight canals were randomly assigned to four groups ( = 10). The root canals were instrumented according to the manufacturers' instructions using single-rotary file systems Hyflex EDM (HEDM), One Shape (OS) and single-reciprocating file systems Wave OneGold (WOG) and OneRECI (OR).
