Well, I know of two. Brigham Young University pre-dent grads have a high dental school acceptance rate and are well prepared to face the initial rigors of dental school. The University of Washington science departments do a good job of preparing prospective dental students for the Bio, GChem, and OChem sections of the DAT.
I wouldn't worry about choosing a college solely for the purpose of getting into dental school.
Whichever college you attend, if you are willing to put out the effort in the relevent courses (i.e. pre-dental requirements), you will do fine.
I wouldn't worry too much about the DATs. I took the DATs in my senior year of college long after I completed all the predental courses (in freshman and sophomore years!), with just one month of Kaplan preparation and reviewing test questions from bookstore DAT testbooks and scored a 21 total.
If you got the desire and fortitude to achieve the goal, you can do it no matter what college you attend.
UBTom's got it right. I went to a no-name college for 3 yrs. before transferring to a well-known university. I had a 3.8 before transferring. At my interview the professors said I should have stayed at podunk college and finished my pre-reqs
I don't think the name of the school matters much....maybe the Ivys carry some weight but I doubt there's any sort of grade adjustment for the 'great' colleges.
