Abstract
Abstract
Objective
The effects of brushing on shaping with different instruments was assessed in oval canals.
Design
Mandibular incisors were assigned to 6 groups (n = 12/group) according to the system, each one with or without brushing: Reciproc Blue, VDW.Rotate, and Race EVO. Micro-computed tomography was performed before and after preparation.
Results
Brushing strokes caused no increase in canal volume, surface area, and structure model index independently of the system (p > 0.05), except RaCe in full canal surface area (p < 0.05). Brushing did not increase the prepared areas (p > 0.05), except for Reciproc in apical canal (p < 0.05). Reciproc with no brushing exhibited less pericervical dentin than with brushing (p < 0.05), while RaCe with brushing resulted in less remaining dentin (p < 0.05).
Conclusions
In conclusion, brushing motion had no effects on the overall shaping performance of the 3 instruments tested. An exception was the increase in prepared surface area in the apical canal segment when the Reciproc instrument was used with brushing strokes.
