Endo Questions for the RWE Faculty:: Reciproc vs Rotary study showing more cracks on rotational motion
The incidence of dentinal cracks during root canal preparations with reciprocating single-file and rotary-file systems: A meta-analysis
Xi WEI1,2,3*, Bo HU2,3,4*, Haiyang PENG1,2,3, Ming TANG1,2,3 and Jinlin SONG2,3,4
I recently read this journal of analysis on reciprocating file systems vs rotational and wanted to clarify if I am missing something about this journal, from what I gather, the RWE approach is mostly rotational because it would cause less apical extrusion of debris and product less dentinal cracks but this journal seems to state the opposite.
Would love to hear a response from RWE about the validity of this journal and if this changes anything about the RWE approach.
Clinically, you have to push on rotary files while you have to pull on the rotating files. This significantly greater pushing force should technically translate into more force in susceptible teeth. If you have you used both rotation and reciprocation in the same exact block you quickly realize how much harder you have to push when using single file reciprocation if you want to achieve similar efficiency as rotation. With rotation, your apical pressure should be the same you use on a sharp pencil. With Single File Reciprocation it's the same pressure you use on a ball point pen that's out of ink!!!
But if this technique works for you and you like it then use it. Ultimately, instrumentation is only part of your success. More important factors are at play to determine the case outcome than the motion of instruments while shaping. Anyway.
Have a good day! :) Al.
