If you're located in Chicago, then you have a really good shot at University of Illinois-Chicago as they are very friendly to in-state students.
According to 2011 ADEA Official Guide to Dental Schools, which are self-reported by the schools, they had 462 in-state applicants and interviewed 189 of them with 62 enrollees (they probably gave more acceptances than this), while they had 1241 out-of-state applicants and interviewed only 25 of them with 6 enrollees (with 3 of them coming from Minnesota).
And their DAT averages were 19.1 AA, 19.1 TS, 19.4 PAT
3.5 oGPA and 3.5 sGPA averages
