The development and design of these instruments has been referred to earlier, and should be referred to in conjunction with this description of technique. Each manufacturer of these instruments produces a protocol for use for their own specific product. As it would not be appropriate to describe any single manufacturer s techniquehere, the description which follows must therefore be generic.
The basic concepts are the same whatever the instrument chosen. The technique for use is crown-down, with copious irrigation. Indeed, these instruments conform totally to the stated objectives in modern root canal therapy, shaping the canal rapidly and efficiently so that thorough cleaning of the root canal system can be carried out with appropriate irrigants. The files must be used in a slow-speed, controlled torque motor, or they
are prone to fracture.
