ABSTRACT
Aim: The aim of this study was to compare the amount of apically extruded debris with three endodontic rotary nickel-titanium instruments i.e Twisted File Adaptive System, ProTaper Gold and ProTaper Next, Materials and Methods: Freshly extracted non-carious 60 single rooted mandibular premolars were selected, prepared and filled with gutta-percha and AH Plus sealer (Dentsply, Germany) using the lateral compaction technique. The teeth were randomly divided into 3 groups of 20 for removal of the root filling material with TFA, PTG, and PTN files. The apically extruded debris was collected in pre weighted Eppendorf tubes. The time for gutta-percha removal was recorded. Data were statistically analyzed using Kruskal-Wallis and 1- way analysis of variance tests. Result: The amount of debris extruded was PTG> TFA > PTN, respectively. Compared with the TFA group, the amount of debris extruded in the PTG group was statistically significantly higher (P<.001). There was no statistically significant difference among the TFA, PTN and PTG groups regarding the time for retreatment. (P >.05).
