One thing I'll point out is that the tired argument is that omfs only get 4ish month in anesthesia...but they spend 3 years (at least) doing tons of the type of sedations they will run in private practice under attendings' guidance
I don't think you could ever compare them to an anesthesiologist, but to say they operate under only 4 months of training is misleading
Oh, but they should all use a dental anesthesiologist
