The Use of a Reciprocating Handpiece to Create a Glide Path in Curved Canals: Comparison with Manual Glide Path Preparation
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 (N=42) 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.
