Evaluation of apically extruded debris using protaper universal, protaper next, one curve, Xp shaper, and edge file: An in vitro study

Abstract

Introduction: Effective chemo-mechanical debridement is essential for a successful endodontic treatment. The present study aimed to determine the quantity of apical extruded debris during instrumentation by Protaper Universal (PTU), Protaper Next (PTN), One Curve, Xp Shaper, and Edge file systems. Materials and Methods: Fifty human maxillary first molars were chosen for this study. The palatal roots of teeth were decoronated using a diamond disk at length 13 mm, Then 50 samples were randomly divided to five groups (n = 10) (Group I: PTU file; Group II: PTN file; Group III: One Curve file; Group IV: XP Shaper file; and Group V: Edge file). After instrumentation, the root-cap assembly was detached from the glass vial. After that, the outer surface of the root was rinsed in the vial by 2 mL of normal saline to eliminate any debris that could have attached to it. The samples’ vials were stored in a hot air oven for 2 h at 100°C to allow moisture to evaporate before the debris was weighed with an electronic balance that had a 0.0001 g precision. Results: The data were statistically analyzed, and the greatest amount of extruded debris was in the PTU file (mean = 1.596), which had a statistically significant difference (P < 0.05) with all other groups. Conclusion: Even after taking the study’s limitations into account, apical debris extrusion was observed in all groups. In contrast to the PTU file system, which exhibited the greatest value, the One Curve file system showed the lowest mean value of apical extrusion debris.
