RESUMO
O objetivo deste trabalho foi avaliar a presença de desvio apical e a conicidade do preparo após a instrumentação de giro alternado NSK, utilizando-se limas tipo K-Flexofi le (Grupo 1) e instrumentação com o sistema Protaper (Grupo 2). Trinta canais simulados, com curvatura, foram divididos aleatoriamente em dois grupos e instrumentados pelos diferentes sistemas. A análise dos resultados (Exato de Fisher), obtidos de imagens por meio de uma plataforma radiográfica, demonstrou não haver diferença estatisticamente significante quanto à avaliação da presença de desvioentre os dois sistemas. No entanto, o instrumento Protaper manual obteve melhor qualidade de preparos dos canais radiculares (p<0,05).
ABSTRACT
The present study evaluated the presence of apical deviation and tapering in preparations performed with the use of the automated handpieces with alternate motion, the NSK (Group 1), and instrumentation manually with Protaper (Group 2). 30 simulated roots were divided into two groups and prepared according to each technique. The alteration caused by root canal preparation was analyzed by radiographs obtained by a radiographic desk specially made for the study. The results (Fishers exact) demonstrated that there wasnt significant statistically differences between the two systems as to the evaluation of the presence of apical deviation. However, the system Protaper produced a greater tapering of the root canals (p<0,05).
