The XP-3D Shaper and FInisher have ushered in a new era of endodontic instrumentation. These anatomically dedicated files are at the epicentre of bio-minimalistic preparation of the root canal space. Euphemistically called the TAPER and the SCRAPER, these instruments can debride and shape a canal while maintaining the native anatomy. For over two decades, there has been cognitive dissonance regarding the obvious; canals are predominantly ovoid; however every file save one, has been manufactured from a round blank. Regardless of the design modifications made to the perimeter of the blank, a round file can only augur a canal, in places thinning the root. The concept of a file shaping a tooth RATHER THAN a tooth shaping a file is a paradigm shift long overdue.
