Comparative Evaluation of Apical Debris Extrusion During Root Canal Preparation Using Two Different Rotary File Systems: “A Wave One Gold and Hyflex EDM Rotary File Comparison”

Abstract

Background: Apically extruded debris following root canal treatment leads to postoperative complications like inflammation, postoperative pain, and delay in periapical healing. Additionally, debris extruded during treatment is responsible for persistent apical area inflammation. Hence, a decrease in debris extrusion is necessary for reduction in postoperative complications. Aim: Two distinct instrumentation methods were used to measure the amount of apically extruded debris after root canal preparation in the present study. Materials and Method: Idea was to include thirty extracted single rooted human premolar teeth for study purpose. After access opening, canal patency was established using a 15 K-file till the apical foramen then it is to be followed by determination of working length by visual method. The samples were divided into 2 groups: Group1: Wave One gold. Group 2: Hyflex EDM Rotary file. The manufacturer’s instructions were followed for the instrumentation. During instrumentation, extruded debris and irrigants were collected into the preweighed test tubes. Following this, these tubes were stored in an incubator at the temperature of 70°C for the next 5 days. To assess the resultant weight of extruded debris, the test tubes were weighed. The final mass of the extruded debris was calculated by subtracting the weight of the initial empty vial from vial containing dry debris. Result: According to the results obtained in this study, both the tested files caused extrusion of debris apically. The h debris extrusion in Hyflex EDM system was reported to be highest, whereas WaveOne Gold showed the lowest value. Conclusion: Result of this study showed that Waveone gold was associated with less debris extrusion in comparison to hyflex EDM rotary file.
