Root canal area increase promoted by the EndoSequence and ProTaper systems: comparison by computed tomography

Ricardo Affonso Bernardes et al. J Endod. 2010 Jul.

Abstract

Introduction: The aim of this study was to compare the increase of the root canal area after instrumentation with EndoSequence or ProTaper rotary systems.

Methods: Twenty-two mesial root canals from mandibular molars were instrumented. Teeth were mounted on a base, numbered, and divided into 2 groups; teeth from 1-11 (PT group) were instrumented by using the ProTaper system, and teeth from 12-22 (ES group) were instrumented by using the EndoSequence system. Cone beam computed tomography was performed on all teeth before and after instrumentation. Measurements at 3, 5, and 7 mm as well as differences in instrument performance were statistically compared by the Student t test at 5% significance level.

Results: Both systems increased significantly the root canal area (P < .05) at all levels. Comparison between the rotary systems showed significantly greater increase (P < .05) for EndoSequence at 3 mm, with no statistically significant difference (P < .05) at the other levels.

Conclusions: Both rotary systems increased significantly the root canal area.
