@Auste Liegute: I very much limit the use of hand files in my personal instrumentation protocol since I use a strict crown down protocol. However, I generally recommend the less experienced user to make sure the canal is at least open to a size 10 hand file, and or ideally a size 15 hand file before attempting to get to the apex with rotary files. This is a matter of preference and safety. I have done enough cases to know how to use the rotary files gently enough not to over torque them in a tight canal. So, I don’t necessarily teach what I do myself since it takes a certain number of cases before people are comfortable doing what I do. I also use hand files 6 and 8 and occasionally 10 in very very calcified cases. So, there still are cases I use hand files but in general I use rotary files exclusively, especially now with the EndoSync+ where even my working length measurement is done with rotary files (generally either a 15/02 ESX or a 17/04 EndoSequence Scout.) Cheers!
