BACKGROUND Aberrations in the root canal anatomy are clinically challenging for clinicians. Mandibular first molars usually have 2 roots and 3 or 4 canals, but various combinations may exist. A distal root with three canals is rare and its incidence in literature is about 0.2 - 3%. As a diagnostic tool, cone-beam computed tomography (CBCT) may be a better(More)
The possibility of extra canals in mandibular premolars is quite low; however, it must be taken into account in clinical and radiographic evaluations during root canal treatment. This case series describes the presence of one root and three canals in mandibular premolars in three patients. The case series underlines the importance of complete knowledge(More)
OBJECTIVES A curvature leads to asymmetrical removal of root dentine, which results in an increase in the incidence of canal transportation. The aim of this study was to evaluate the effect of master apical file (MAF) size on the apical transportation (AT) of teeth with severe canal curvatures. METHODS Thirty-six mesial roots of human mandibular first(More)
The apical third of most root canals shows some degree of curvature, which is important in cleaning/shaping and obturation during root canal treatment. The present study evaluated the effect of master cone size on the apical seal of severely curved root canals. Thirty-eight mesial roots of human mandibular first molars were prepared using the crown-down(More)
