The study was performed using NickelTitanium instruments 25/0.06 evaluated in canals with a 45-degree curvature and 2-mm radius. The analyses evaluated two parameters: fracture by cyclic fatigue, and time of fracture; in addition, the length of separated fragment was evaluated. Medians and range values were calculated for each group. Data were analyzed by the Kruskall-Wallis and Mann-Whitney U tests to determine statistical difference. The ProFile motor-driven rotator system exhibited highest resistance to fracture due to cyclic fatigue and highest fracture time compared with the ProTaper and Mtwo systems (p <0.05). The equipment proposed in this study (AED) demonstrated efficiency for recording information, automation, scheduled work times and durations, cycle number, time of fracture, pressure changes and, principally control of the human factor. 2017 artículo científico 1659-1046 https://www.redalyc.org/articulo.oa?id=499555011007 https://www.redalyc.org/journal/4995/499555011007/ https://www.redalyc.org/journal/4995/499555011007/html/ https://www.redalyc.org/journal/4995/499555011007/499555011007.epub https://www.redalyc.org/journal/4995/499555011007/movil 10.15517/ijds.v0i0.27288 en http://www.redalyc.org/revista.oa?id=4995 Odovtos - International Journal of Dental Sciences application/pdf Universidad de Costa Rica Odovtos - International Journal of Dental Sciences (Costa Rica) Num.1 Vol.19 |
