Comparison of different rotary files system during root canal preparation seen under stereomicroscope

Abstract

Abstract
Background: To compare different rotary files system during root canal preparation seen
under stereomicroscope.
Materials & Methods: A total of 45 premolars from the maxillary and mandibular regions,
extracted for orthodontic purposes, were included in the study, with two contralateral teeth
from each individual. This study was done in GDCRI, Ballari. The specimens were divided
into three groups, each consisting of 15 canals. These replicas were then evaluated under a
stereomicroscope. Chi-square test was done. The results were analysed using SPSS software.
Results: The measurement of canal preparation time, revealed a mean time of 10.22 minutes
for hand K-files preparations and a mean time of 8.15 minutes for rotary Profile preparations.
This difference was found to be statistically significant with a p-value of 0.03.
Conclusion: Rotary instruments appear to present significant advantages in terms of
efficiency and operational integrity.
