Comparison of ProTaper Ultimate, TruNatomy, and Rotate rotary files in apical debris extrusion

Abstract

Aim: The aim of this study is to evaluate the amount of debris extruded apically by the primary shaping files of three rotary file systems manufactured with different alloy technologies [TruNatomy (TRN), ProTaper Ultimate (PTUltimate), and VDW.Rotate (VDW.R) files].

Methodology: Thirty lower premolar teeth with moderate curvature (10-20°) were randomly divided into three equal groups (n=10) according to three rotary file systems [TRN (26.04v), PTUltimate (25.08v), and VDW.R (25.06v)]. The debris extruded apically was collected in Eppendorf tubes of known weights. After preparation, the tubes were placed in an incubator at 70°C for five days to evaporate the distilled water. The tubes filled with debris were then weighed again, and the net weight of the extruded debris was calculated in grams (g) by subtracting the initial weight from the final weight. The data were analyzed using one-way ANOVA test.

Results: There was no significant difference in the amount of debris extruded apically by the three shaping files (p > 0.05). The highest amount of debris extruded apically was 0.9534 g for PTUltimate. VDW.R extruded the minimum amount of debris apically, with 0.1833 g.

Conclusion: All rotary files have caused apical debris extrusion. Even though there was no significant difference among the files, the VDW.R file extruded less debris compared to other file systems.
