The Self-Adjusting File may seem passive and delicate, but its ability to adapt to the natural shape of the canal and remove the infected dentin in a very conservative manner, while simultaneously delivering continuous irrigation – allow it to achieve an extremely high level of cleanliness, as shown in dozens of scientific researches. Just to quote a few:
- Siqueira et al., J Endod 2010: SAF was able to completely disinfect 80% of the canals (Rotary: 45%).
- Paqué et al., Int Endod J 2012: SAF shows 1.3% debris when used with NaOCl + EDTA (ProTaper: 7.9%).
- Lin, Shen, Haapasalo, J Endod 2013: SAF left 3.25% of a thin groove covered by bacteria (26.98% after K-File, 19.25% after ProFile).
