AET technique or the anatomic endodontic technique is a step back approach and the SX file from Paul's is a crown down type file so you're talking about marrying this step back approach of the ultradense system with an initial crown down approach state to gain access to the deeper regions of the canals after yes the SX basically facilitates the placement of your standard. K files and you then prepare a prickly to whatever the instrument will go to and that's really dictated by the anatomy of the tooth so as an example I would use the SX to crown down but maybe 1314 mm then I would use for apical patency a 10 or 15 K file if the 20 goes to measurement would use a 20 at that point I would introduce from altered and their. Number one shaper and then in tandem go back to the K files which would then include 20 5K then followed by their see shaper which is used in curve canals in the teeth and I normally treat which is every tooth all canals a curve so I include that routinely that would be followed by 30 K file than the number two in a number three shaper of course in larger canals. You may find that your shapers actually go to measurement and the thing is also critical to understand that measurement is not a static thing measurement changes as you reduce the curvature so you have to on occasions just check your measurement because your apical patency you may be a millimeter or two shorter than your initial measurement so you have.
