One of the most important things during root canals is working length. But how many times have you tried to figure out what exactly is the definition of working length? For me - it’s been a lot.
A great friend and mentor of mine re-showed me a US Navy paper on Working Length and it honestly, has changed my game. It’s made my Endo practice so much more predictable. It works with all apex locators. Next we’ll talk about losing length during Endo procedures and making sure that I I don’t over instrument the apical third.
