Obtained three-dimensional images of the tooth and the root canal system allow an understanding of the anatomical features and techniques used during endodontic treatment. The computed microtomography (¼CT) is an important tool both for the evaluation of new clinical protocols.The ¼CT was described by Nielsen et al. (1995) as one advanced methodology for endodontic research, highlighting the ability of this method to introduce morphologies internal and external teeth without the need of destruction of samples.Many investigations have used ¼CT to study the morphology and anatomy of the root canal system (Bjorndal et al. 1999; Vertucci, 2005; Swein and Xue 2009; Fan et al. 2010), in research on the determination of the working length (Paque et al. 2010), the evaluation of new techniques and instruments for root canal preparation (Loizides et al 2007, Moore et al. 2009; Freire et al. 2010), in analyzing the removal of debris with different protocols and irrigation methods (Wiseman et al. 2,011; Paque et al. 2011) and to investigate the efficiency of the root canal obturation techniques (Hammad et al. 2,009; Endal et al. 2011).The objective of this work is ti use ¼CT to evaluate different techniques of instrumentation and obturation of the root canals and their interrelationships.
