I have been to both schools this cycle and I honestly felt a better, family oriented atmosphere at Meharry, something I did not felt at UIC.
UIC dental students seemed very competitive and stressful when I talked to them, while Meharry students were more laid back and helpful. Their class size is small.
Of course this is subjective, but nonetheless I would go with Meharry if I was in your shoes. They also have a brand new diagnostic imaging lab. UIC's lab except for the very few that the administrations shows you on the tour, are pretty old. Good luck with the decision and congrats into getting both!
