          Abstract

          O objetivo do presente trabalho foi averiguar a ocorrência de desvio apical e a conicidade do preparo resultante do emprego de técnica de instrumentação seriada em raízes mésio-vestibulares de molares superiores variando-se o tipo de instrumento (limas tipo K e Flexofile). Após o preparo, as raízes foram diafanizadas e submetidas a exame macroscópico com auxílio de lupa de 8 graus positivos. Dos resultados, consta que a lima Flexofile propiciou menor ocorrência de desvio apical, bem como melhor qualidade de preparos cônicos contínuos

          The aim of this study was to verify the occurrence of apical deviation and tapering in preparations performed with the use of the standardized technique in mesiobuccal roots of upper molars while varying the type of instruments used (K-type file and Flexofile). After preparation, the roots were made transparent and submitted to examination. The results showed that Flexofile produced a smaller incidence of apical deviation and greater tapering of the root canals

          The anticurvature filing method to prepare the curved root canal.

          The anticurvature filing method maintains the integrity of canal walls at their thin portion and reduces the possibility of root perforation or stripping. With this method, the dental practitioner maintains digital control over the endodontic instrument, and the preparation of the curved canal is eased.
