you are wrong. lots of dental schools are very heavily into research. I go to UF, and we are the 4th highest NIH granted school, and there are lots and lots of opportunties for students to do research. now, i understand what you are saying in your above posts; you are taking the OP extremely literally. obviously no dental school is completely "research-based," but there is definitely a difference in the available research opportunities at different schools.
if not, why do some schools offer a combined DMD/PhD program? what is that PhD for? just to make people call them Doctor Doctor? some schools are very research-intensive schools, and if you dont believe me, check this out:
