The SAF provides a very high level of safety in treatment. This is reflected in the following aspects (see other questions on this FAQ section to read about the various aspects):
- There is no risk of creation of dentinal micro-cracks, since the SAF is hollow and cannot inflict much force in its operation.
- The use of no-pressure irrigation allows using copious amounts of sodium hypochlorite without the danger of sodium hypochlorite accidents.
- The risk for file separation is extremely low, and is as low as 0.1%.
- The risk of apical extrusion of debris is very low, due to the continuous no-pressure irrigation.
- The risk of canal transportation or perforation virtually doesn't exist, and was shown in various researches to be significantly lower than other instruments.
- The SAF shapes the canal in a minimally-invasive way, leaving as much sound dentin as possible.
This way, the SAF provides a very high level of cleanliness in the endodontic treatment, without the need to compromise on the various risks and damages created by other instruments.
