Quantitative analysis of apically extruded debris between selective rotary and reciprocating files by lyophilization & micro-balance

Original Research

Abstract

Background: Extrusion of debris during root canal preparation into the periapical tissues, result in inflammation of the periodontal ligament. This may result in postoperative discomfort, flare-ups, or even apical healing failure, which could negatively impact the effectiveness of the endodontic therapy. This may result in postoperative discomfort, flare-ups, or even apical healing failure, which could negatively impact the effectiveness of the endodontic therapy.

Aim and Objectives: This study compared the amount of debris extruded from the apex during apical preparation using a reciprocating file system versus a rotary file system.

Materials and Methods: Twenty mandibular premolar teeth were divided into two groups at random. The root canals were created utilising rotary and reciprocating file systems in accordance with the manufacturer's specifications. During instrumentation, apically extruded material was gathered in preweighed tubes. The preweights and postweights of the tubes were subtracted to get the net weight of the apically extruded debris.

Results: The statistical analysis was done with parametric techniques (Independent t test). Tukey multiple comparisons were used for post hoc pairwise comparisons. 0.05 was chosen as the alpha-type error value. A significant difference was discovered between the Protaper Universal (PTU) rotary system which extruded more debris than the Wave One Gold (WOG) reciprocating system.

Conclusion

WaveOne Gold extrudes less debris compared to ProTaper Universal file system. So according to this study Wave One Gold can be used without harm in the current clinical practice.
