There are only two dental schools in Florida, Nova Southestern and The University of Florida.
From what I know, UF is extremely hard to get into if you are out of state. They look at the in-state applicants first. On UF's website they give you the stats of the people that were admitted if you want to check that out. Nova is a private school so they don't really look at your residency.
There is one state dental school (uf) and two private schools (nova and lecom). UF is not OOS friendly but if you have great stats and are URM you still have a shot.
