In vitro evaluation of post-instrumentation foraminal deformation in mesial canals of mandibular molars comparing Endogal Rotary and VDW Rotate
https://doi.org/10.36377/ET-0132
Abstract
AIM of this in vitro study was to compare apical foraminal deformation at 3 mm from the tomographic apex after instrumentation of mesial canals of mandibular molars using two rotary systems: Endogal Rotary and VDW Rotate.
MATERIALS AND METHODS. Thirty extracted mandibular molars were used and embedded in silicone impression material to facilitate tomographic analysis. The samples were randomly divided into two groups (n = 15): Group A was instrumented with the Endogal Rotary system, and Group B with the VDW Rotate system. All teeth were scanned using tomography before and after instrumentation. Measurements were taken at 3 mm from the apex in axial sections using NNT Viewer software. The distances between canal walls and intercanal space were measured. Statistical analysis was performed using independent t-tests with a significance level set at 5%.
RESULTS. No statistically significant differences were observed between the two groups for any of the evaluated parameters. Both rotary systems preserved the anatomy of the root canals and prevented excessive dentin removal in the apical third.
CONCLUSIONS. The Endogal Rotary and VDW Rotate systems demonstrated similar performance in maintaining apical anatomy and minimizing foraminal deformation at 3 mm from the apex. Both systems are suitable for shaping mesial canals in mandibular molars with minimal structural compromise.
