Go to the school you feel most comfortable with.
I believe specialty placement is really up to the student. Let me put it this way: You can, say, go to Penn, but then it becomes more difficult to do as well relative to the class compared to Buffalo. Would you feel a lot happier being higher up in class ranking or being mediocre or less in one school--or would you fall apart in school knowing that you aren't anyone special? Or would you be happier in a school with supposedly better "reputation" or specialty placement rates--though that can be an illusion b/c the school can have more competitive or harder working students--or the education really is better?
Again, I am a believer that happiness (or psychology) is a predictor of how well you'll ultimately do in dental school and, if you desire to do so, specialize. Being in a school for four intense years can really get into you if you are not happy.
