Abstract:
Introduction Prior to introducing rotary instruments into the root canal system, manufacturers recommend creating a glide path to reduce the risk of instrument fracture due to taper lock. This study compared manual preparation of a glide path with mechanical preparation using a reciprocating hand piece in severely curved canals. Methods Mesiobuccal roots of eighty-four human maxillary molars with severe curvature 20-48 were selected. The teeth were decoronated and working length established 6 K-file. Samples were divided into two groups N42 according to glide path preparation with K-files 8-20. Group 1 manual preparation, Group 2 mechanical preparation with files in a reciprocating hand piece. Preparation time for each method and incidence of adverse outcomes file separation , perforation, and ledge creation were recorded.
