UofM,
I was also wondering if Nova was still your first choice? Maybe you'll decide after the interview that you'll like IU. Steiner and I have talked about their interview day before, and I was not impressed when I went. It's very short, relatively uninformative, and not as professional as other schools I've visited. You probably won't be there for more than a couple hours!!
However, after reading his posts and talking with others, I realized that it may not usually be like that and the students are very happy with the school. Also, their board results are really high if you plan on specializing. Obviously their facilities are not as nice as Nova, but I would have to say that IU has a very respected and established dental program. It is, however, very expensive if you're out of state, which is the main reason for my concern. I would be very interested in hearing your interview experience to see what you thought of it as compared to Nova.
Good luck at the upcoming interview! It's very laid back and you'll probably be interviewed by 2 faculty members and 1 student at one sitting. If you could also ask a question for me I would really appreciate it. Can you find out how many of their students get accepted to specialty programs each year, on average? Thanks alot!
