English abstract The present study conducted an in vitro evaluation of the presence of apical deviation on the root canal preparation of the mesiobuccal roots of human maxillary molars employing automated handpieces with continuous motion, the Pow R system (Moyco Union Broach), and alternate motion, the M4 system (Kerr). Analysis of the presence of apical deviation was carried out by means of radiographs obtained on a radiographic desk fabricated for the study. The results demonstrated the lack of statistically significant differences between the two systems as to the evaluation of the presence of apical deviation. There was no correlation between the degree of curvature of the roots and the degree of apical deviation for the continuous motion system. However, there was a statistic difference for the alternate motion system, with a direct correlation of moderate degree
Portuguese abstract O presente trabalho avaliou, in vitro, a presença de desvio apical no preparo de canais radiculares em raízes mésio-vestibulares de molares superiores humanos utilizando-se de peças automatizadas de giro contínuo, sistema Pow R (Moyco Union Broach) e giro alternado, sistema M4 (Kerr - USA). A análise da presença de desvios apicais foi realizada por meio de radiografias obtidas na plataforma radiográfica confeccionada para o experimento. Os resultados mostraram não haver diferença estatisticamente significante quanto à avaliação da presença de desvio entre os dois sistemas. Não houve correlação entre o grau de curvatura das raízes e o grau de desvio apical, no sistema de giro contínuo. No entanto, o sistema de giro alternado apresentou diferença estatística de correlação direta e grau médio
