I'm currently at Buffalo's DDS program, so I am a little biased. But if I were you, I would think long and hard about passing up in-state tuition to go to a more expensive school elsewhere. Roughly, it looks like Pitt costs about $100,000 more than in state at Buffalo. Contrary to what a lot of naive pre-dents on this board seem to think, an extra $100,000 in tuition is a lot of money, and it is not something you should easily dismiss.
I mean no disrepect towards Pitt or to the previous poster, but I would really think hard about whether a Sim Lab, IV sedation, etc. are really worth the extra $100,000.
For what its worth, I'm from Boston, and I passed up two big-name Boston private schools (BU and Tufts) to come to Buffalo. Both BU and Tufts allegedly had lots of great facilities, but I couldn't justify $300,000 for those schools when I could come to Buffalo for $150,000. And so far, I have no regrets, and I have a lot of classmates here who passed up expensive private schools to come to Buffalo too.
Good luck in your decision. And regardless of whether you go to Buffalo or Pitt, you'll be great clinician after 4 years.
