# Comparison of Debris Extrusion and Preparation Time by Traverse, R-Motion Glider C, and Other Glide Path Systems in Severely Curved Canals

## TL;DR

This study compared how much debris is pushed out of curved canals and how long it takes using different dental tools.

## Contribution

The study introduces new comparative data on debris extrusion and preparation time for various glide path systems in curved canals.

## Key findings

- Traverse extruded the highest amount of debris beyond the apex.
- R-Motion Glider C required the least preparation time.
- Traverse preparation time was almost half of HyFlex EDM Glidepath.

## Abstract

This study evaluated debris extrusion by Traverse and R-Motion Glider C during glide path preparation. Seventy-five mesial roots of mandibular molars with severely curved mesiobuccal canals were distributed into five groups: Traverse, R-Motion Glider C, HyFlex EDM Glidepath, One G, and R-Pilot. During the glide path preparation, debris extruded beyond the apex were collected. The debris weight was calculated (in mg), and the preparation time was recorded (in s). All the systems extruded debris beyond the apex; Traverse extruded the highest amount followed by HyFlex EDM Glidepath, R-Motion Glider C, One G, and R-Pilot (p  < 0.01). Traverse required almost half the duration of HyFlex EDM Glidepath to prepare the canals (p  < 0.01), while R-Motion Glider C required the least time (p  < 0.05). Traverse extruded the highest amount of debris, whilst R-Motion Glider C extruded similar amounts of debris to HyFlex EDM Glidepath, One G, and R-Pilot systems.
