SAF system, was recently introduced by ReDent-Nova . The SAF is a hollow file designed as a compressible, thin-walled, pointed cylinder 1.5 mm in diameter and composed of 120-micro meter-thick nickel-titanium lattice. The SAF is operated using a trans-line (in-and-out) vibrating handpiece head (RDT3, ReDent-Nova) that generates 5,000 vibrations per minute at an amplitude of 0.4 mm. This innovative file is claimed to adapt itself to the 3D canal morphology both longitudinally and cross-sectionally.
