Abstract

Apparatus and methods for an articulating endodontic file are provided. The apparatus may include two or more file segments. Each file segment may articulate with respect to an adjacent file segment. The articulating file may include a joint between two file segments. The articulating file may include a first joint that allows a file segment to articulate in a first direction. The articulating file may include a second joint that allows a second file segment to articulate in a second direction. The articulating file may be configured such that torque applied to a first file segment is transmitted to one or more other file segments in the file.
