I am an Air Force dentist and I just finished a 1-year AEGD residency. I am licensed to do conscious sedation. According to the ADA guidelines, one must have a minimum of 60 didactic hours and 20 supervised cases of sedation to apply for a license. My residency provided this for me. As all you OMFS residents are aware, there are multiple planes of sedation. I am limited to conscious sedation. Therefore the "magic" propofol is off-limits to me. In my residency, I worked cases where the attending OMFS would come in and load up the propofol, but then it became a "general" sed case and I could not count it as one of my observed sedations. We also spent 1 day a week during our OMFS rotations in the general anes room where the OMFS residents were the acting anesthesiologist while a staff OMFS removed 3rds. So I have seen propofol used many times and I agree that it is a great med but I personally would never use it b/c I have no formal training with it. I mostly use versed/fentanyl but I have used some valium/demerol as well (mostly older pts). Our didactic courses focused on the meds I mentioned, nothing really about propofol b/c it takes the pt deeper than I am trained to manage.
I truly value this training b/c it is an option I can now give my pts both now in the AF and later if I separate and enter private practice. I cannot speak for the perio residencies but their training may be along the same lines as mine. The purpose of the anesthesia training I recieved is very different than the anesthesia training of an OMFS. I can make pts tolerate an uncomfortable procedure when I do crown lengthening or remove 3rds. An OMFS, on the other hand, must have complete control over the full range of planes of sedation, hence the (much) more extensive training in anesthesiology. It would have been overkill for me to have spent 6 months of my 12 month residency in anesthesiology.
