I'll add this: OMFS is a
dental specialty, regardless of whether or not you get an MD. A dental degree is required, while an MD is optional. The residency is traditionally 4 years without the MD or 6 years with the MD. The med school curriculum is integrated into the residency, so you go back and forth from being an OMFS resident to a med student. In theory, the 4- and 6-year programs teach the same thing, because you learn to do OMFS in your residency, not medical or dental school. In reality, some programs are stronger than others in the clinical experience you get, but this is more of a factor of the individual program, not whether or not you get an MD. There are both weak and strong 4-year and 6-year programs out there.
My program is a pretty broad-scope residency although we have both 4-year and 6-year residents. None of our faculty have medical degrees, except a new one we just hired. I like that because it demonstrates the adequacy of our dental background.
Looking at your old posts, it sounds like you may be looking for a back door into med school or an easier way for an MD, but I could be wrong. I'll tell you this is
not the case. Getting into OMFS usually requires you to be in the top 10% of your class and top 10% of board scores in the country. This isn't easy at all. I say this as someone who has done both dental and med school as an OMFS resident.
