ABSTRACT
OBJECTIVE:
The effects of brushing on shaping with three different instruments were 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 for RaCe EVO in the full canal surface area (p < 0.05). Brushing did not increase the prepared areas (p > 0.05), except for Reciproc in the apical canal (p < 0.05). Reciproc with no brushing exhibited less pericervical dentin than with brushing (p < 0.05), while RaCe EVO with brushing resulted in less remaining dentin (p < 0.05).CONCLUSIONS:
The 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.Palabras clave
