Abstract

Introduction: The occurrence of microcracks is rather frequent during the root canal preparation and increases with some endodontic file systems. We conducted this study because there have been few in vitro studies on the incidence of microcracks formation by using the stereomicroscope. This study aims to evaluate and compare the frequency and amount of microcracks formed after root canal preparation in non-surgical root canal treatment using three different types of endodontic file systems (Reciproc, One Curve, and Vortex Blue) using a stereomicroscope. Material and Methods: Forty human extracted teeth were collected and randomly assigned to five groups (n=8) as per the instrumentation protocol: group I: non-instrumented teeth (control); group II: hand K-files; group III: Reciproc; group IV: One Curve; and group V: Vortex Blue. Each group was then instrumented using the assigned file system at the standardized working length. The samples were gathered to be scanned and evaluated after instrumented and sectioned to determine the microcracks under the stereomicroscope with a standardized magnification of 25X. The data were statistically analyzed using one-way ANOVA and chi-square tests. Results: There is no statistically significant difference among the study groups in the number of micro crack formations (p=0.736) and at each section level (3mm, 6mm, and 9mm) (p=1.000). Conclusions: No significant relationship between dentinal micro crack formation and canal preparation procedures with the control and hand k files groups were noticed. While the Reciproc, One Curve, and Vortex Blue systems had caused some microcracks.
