ABSTRACT

Objectives: Check out how reciprocating motion influences in the fracture of Pathfile® files in root canals with higher angles than 25 degrees. Material and methods: 82 root canals of human extracted teeth with higher angles than 25 degrees were randomly divided into 2 groups. In all the root canals glide path was determined with a K#10 file. Group 1 (n=41) was pre-instrumented with Pathfile System® following the manufacturer´s instructions. Group 2 (n=41) was pre-instrumented with Pathfile System® using reciprocating motion, 120 degrees clockwise and 60 degrees counterclockwise. During all the procedure Sodium Hypoclorite 5.25% was used to irrigate. Results: About the overall of instrumented teeth, 3 fractures were produced with reciprocating motion, with 7 and 10 uses, and only one file fractured with continue motion, with 10 uses. Conclusions: Nowadays is safer to use the Pathfile® files with continue motion.
