Highly flexible to minimize canal transportation, the files feature a unique S-curve design and a thin instrument core to deliver outstanding cutting efficiency while respecting natural root-canal morphology. Only two files in sizes 025 and 035 are required for most root-canal preparations. Their .04 taper promotes optimal debridement of the canal, maintains file flexibility and thus reduces preparation errors, and permits ideal shaping of the root canal for subsequent obturation with any method.
The F360 files are employed in a torque-limited motor and used in a picking motion up to a predetermined working length. The same torque (1.8 Ncm) and speed values (250-350 rpm) are utilized for all files; doctors need not adjust speed or torque upon changing files during the preparation sequence.
