In vitro comparison of post-instrumentation preparation to identify pericervical dentin wear in mesial canals of mandibular molars

https://doi.org/10.36377/ET-0192

Abstract

AIM. The present study aimed to compare the level of wear in the pericervical dentin of the mesial canal of the first mandibular molar using two types of endodontic file systems.

MATERIALS AND METHODS. 30 extracted human first mandibular molars were selected and divided into two groups of 15 teeth randomly to which an initial CT was performed. Group 1 was prepared with the Rotate NiTi file system and for group 2 the Endogal system was used. After the preparation of canals, a final CT was taken and the respective measurements were made comparing the beginning and end. Intergroup comparison was performed with independent t tests.

RESULTS. No statistically significant differences were found between the two groups of files with a value of 1.64 mm for Endogal and 1.92 mm for Rotate.

CONCLUSIONS. It is concluded that the pericervical dentin was preserved by conserving its anatomy, when using the two types of rotary file systems for the preparation of the root canals.
