ABSTRACT
ABSTRACT The present study evaluated the presence of apical deviation and tapering in preparations performed with the use of the automated handpieces with continuous motion, the K3 Endo system (Group 1) and instrumentation manually with Protaper (Group 2). 30 simulated roots were divided into two groups and prepared according each technique. The alteration caused by root canal preparation was analyzed by radiographs obtained on a radiographic desk fabricated for the study. The results (X2), demonstrated that the K3 Endo produced a smaller incidence of apical deviation and Protaper produced a greater tapering of the root canals.
RESUMEN
RESUMEN El objetivo de este trabajo fue evaluar la presencia de desviación y conicidad adecuada apical con el uso del sistema de instrumentación de movimiento continuo K3 Endo (Grupo 1) respecto a la instrumentación manual realizada con Limas Protaper (Grupo 2). Treinta canales curvos simulados fueron divididos aleatoriamente en dos grupos e instrumentados por los diferentes sistemas. La alteración causada por la preparación de los canales fue analizada en radiografías obtenidas, en placas ad hoc. Los resultados (X2) demostraron que el K3. Endo produjo una menor incidencia de desviación apical y Protaper produjo una mayor conicidad de los canales radiculares.
