ABSTRACT

O presente estudo verificou se a pré-instrumentação com limas PathFile diminui a possibilidade de desvio apical durante o preparo endodôntico com limas Protaper nos canais simulados em blocos de resina. Foram confeccionadas fotografias antes e após a instrumentação e realizada uma análise computadorizada por meio de superposição das imagens. Os dados obtidos foram tratados estatisticamente com teste T de comparação de médias, havendo diferença estatisticamente significante (p=0,000, t=-25,383). De acordo com os resultados obtidos, concluiu-se que a instrumentação prévia dos canais radiculares com as limas Pathfile (Dentsply®/Maillefer) pode contribuir consideravelmente na redução da possibilidade de desvio no terço apical de canais radiculares curvos.


This study has aimed at verifying if the use of PathFile files minimizes the possibility of apical deviation during endodontic treatment with Protaper files in resin blocks with simulated canals. Digital photographs were taken before and after instrumentation and a computerized analysis through overlapping images. Data were statistically analyzed with t-test for comparison of means, and demonstrated a statistically significant difference (p = 0.000, t = -25.383). According to the results of this research, the authors concluded that previous instrumentation with PathFile (Dentsply©/Maillefer) system can contribute to a great reduction of transportation possibility on the apical third of curved root canals
