+Endo ABO I like the way you think and yes! While it's controversial to say that according to the academics, the reality is if you have a large enough diameter, there's definitely no reason to remove too much dentin in terms of the flare in vital cases. To be fair, the academic argument is that you need more volume of irrigation for tissue dissolution in vital cases. Further more, you have to be exceptionally aseptic in vital cases to avoid contamination. But in general, the argument is over apical enlargement, which I believe should be equally large in both necrotic and vital cases in order to remove the tenacious tissue (some argue that it's actually harder to clean vital tissue than disinfect necrotic cases.)

Then, we should remove enouch dentin for mycrobial control in necrotic pulps cases and save more dentin structure in vital pulp?
