When scouting the apical one-third, after coronal two-thirds pre-enlargement, if a new and straight 15 file can gently 'slide' and passively 'glide' to length, then rotary instruments will generally follow this confirmed and reproducible glide path. In this Just-In-Time segment, topics include: Root canal system anatomy Appreciating viscous chelators Sequencing the preparation Negotiating with hand files Choosing manual vs. rotary * this just-in-time show is going to focus on the glide path and how to manage difficult curved and aberrant canals as we can see from this spinning animation there's a lot of complex anatomy that's dominantly in the apical 1/3 so great access is essential and clinically when we look in the mouth mirror without moving the mirror we should see all the orifices this pulp chamber then can be filled up with a viscous key later such as glide our CPAP or pro lobe the advantages of a viscous key later are it gives us a superior lubricant so we can slide around sheets of fibrotic tissue and denticles that might exist within the canal also we know that we can generate debris in the debris that we're generating can keep the tissue and the debris more effectively held in suspension and finally in vital cases that bleed viscous key layers prevent the reappearance of tissue and pave the way for the introduction of the next file I'm using these instruments with little back-and-forth reciprocating strokes each little back-and-forth stroke draws the instrument a little bit deeper into the canal when the handle is just snug pull you'll shear dentin and you'll be cutting on the out stroke most dentist were trained in Adana CLE to aggressively cut in the canals in this method of canal preparation we're cutting always on the out stroke away from the terminus and to the greater cross-sectional diameters once we've negotiated a few millimeters of the canal little back and forth motions tend to smooth and refine that area of the canal and allow us to reciprocate the handle to pull the file a little deeper down the canal when we're about three rubber stops short we know we have a pretty decent glide path if we can move this instrument in and out reproducibly over the coronal 2/3 push the stop down this will give us the maximum depth of penetration where the canal has been secured and that working length can be transferred to your first rotary or reciprocating file this instrument then can shape that region of the canal and that instrument will never go into no-man's land in other words will always stay inside the secured region now in the presence of a viscous key later we can take a small size file typically for me it's a ten and using little back-and-forth reciprocation motions the files drawn down every time the handle is snug pull feed it in a little bit deeper pull each feed it in pole represents one cutting cycle I'm typically using about six cutting cycles with the ten and another six cutting cycles with the 15 and that will produce enough space to accommodate the first rotary mechanical instrument oftentimes when you get deeper in the canal the instrument just doesn't want to advance rather than attack let's pull out the instrument and let's pre-curved the file placing the curve closer to its working tip notice how the pre-curved file can pass through the pre enlarged canal passively notice how the tip of the file lightly bounces off the lateral walls and when it arrives in the curvature it's remarkably pre-curved little short watch winding strokes draw the instrument around the curve and a little bit deeper in the canal repeated in out strokes smooth and refined so we can reciprocate the handle gently in advance a little deeper towards working length when we get about one stop from our reference point short of the expected full working length let's not reciprocate the file anymore let's slide to length sliding to length prevents ripping and tearing the ferryman it's important to confirm patency move the file in and out my newt Leith roux and do this intentionally and repeatedly until the instrument is slow copy loose well we now need to make a decision between manual versus mechanical finishing this means we need to confirm the glide path since each third of the route is about 3 to 5 millimeters let's pull the intimate back about 1 to 2 millimeters and slide back to length let's pull back three or four millimeters and see if we can slip and slide back to length and finally let's withdraw the 15 file four or five or six millimeters
