I am currently attending Uconn, so I may be able to answer some of your questions. First of all to address the "negative post" about Uconn, most of those posts were written by people whom either didn't get into Uconn, or go into Uconn and subsequently failed out. If that isn't biased information... I'm not sure what is? So just keep that in mind when reading those posts.
Uconn's curriculum is certainly very medical intensive for the first two years. This has it's obvious pro's and con's. They teach you to think like a physician, and then teach you the clinical skills you need to be a dentist. Sure this comes at a cost in terms of how much time you spend in clinic the first two years, but that's why >90% of Uconn grads go into some kind of residency. As the OP mentioned, if your into research this is a great place to be. There are more opportunities for research here, than their are students. The small class size ~45 students is also a plus, in that you will get to know all the faculty and deans very well during your time here. I could go on and on, about random stuff, but I really should be reviewing lung patho. So if you have any specific questions about Uconn, I'd be glad to answer them?
