ABSTRACT
The aim of the present study was to investigate the shaping abilities of XP Shaper and compare it with other single file rotary NiTi systems utilizing full rotation and reciprocation motion, by cone beam computed tomography. Mesiobuccal canals of fortyfive mandibular first molars, were allocated into three equal groups (n=15) according to the rotary system applied; WaveOne, OneShape and XP shaper. Preand postinstrumentation images were obtained at 3mm, 5mm and 7mm from the apex using cone beam computed tomography and assessed to determine canal transportation and centering ability. Data were analyzed using KruskalWallis test to compare the three systems and Friedman's test to compare the root levels. Results showed that WaveOne and OneShape rotary systems produced greatest mean transportation with no statistically significant difference between them, while XP Shaper produced the lowest statistically significant mean transportation. Canal centering ability differed significantly among the three systems used. It was concluded that XP shaper preserved the original canal anatomy better than WaveOne and OneShape rotary systems (AU)
RESUMEN
El objetivo del presente trabajo fue investigar la capacidad de tallado apical de XP Shaper y compararla con dos sistemas de NiTi, rotatorio y reciprocante, mediante tomografías computarizadas de haz cónico. Se analizaron los canales mesio vestibulares de cuarenta y cinco primeros molares inferiores. Los dientes fueron divididos en tres grupos experimentales (n=15) WaveOne, OneShape and XP shaper. Se obtuvieron imágenes pre y post instrumentación a 3mm, 5mm y 7 mm del ápice utilizando tomografías computadas de haz cónico para determinar la presencia de transporte apical y la capacidad de conservación de la anatomía original del conducto. Se utilizó el test deKruskalWallis para comparar los tres sistemas de intrumentación y el test de Friedman para comparar las mediciones en los tres niveles de raíz. XP Shaper mostró la menor cantidad de transporte apical estadística mente significativa mientras que WaveOne y OneShape mostraron el mayor transporte apical sin diferencia estadística mente significativa entre los dos grupos. XP shaper permitió conservar la anatomía del canal original mejor que WaveOne y OneShape (AU)
