University of Utah is not guaranteed either way. They have the money in the bank for the building and operating costs, but need the state to commit 2mil/year to go through with it. Currently it is in the legislature right now, so hopefully we'll know soon. With statewide budget cuts it looks rather grim for 2011, but we can keep our fingers crossed.
as hajibandeh pointed out, we(in Utah) are definitely overpopulated with dentists, but an in state school does not necessarily mean more dentists, it just means the dentists will have less debt. Colorado did a study on the effect of their dental school, and it showed that once their school was operating, there was no net gain of dentists entering the profession in CO. Hopefully that will be the same in Utah
