The integration of the Quantec (0.06 taper 0.25-mm tip) rotary NiTi file and the standard stainless steel K-file (ISO 0.02 taper) synergistically simplifies instrumentation of the canal. The rotary NiTi file is primarily used to flare the coronal and midportion of the canal. Its flexibility enables clinicians to do so without ledging and perforation. Because of its effective cutting ability, the stainless steel file is used to clean and shape the apical area of the canal and blend the apical portion into the flare. Ultimately, this simplifies the obturation process. When familiar with this technique, dentists may find it easier to work with sequential tapers offered in the Quantec series of instruments. This series has a of tapers from 0.02 to 1.2. Understanding the crown-down concept and using quality and reliable instruments facilitates improved productivity.
