I graduated from HU (2009) as predental student. Though they do have the BS/DDS program, it is extremely hard to get into, and even harder to matriculate into dental school...I believe maybe 2 students did out of 10 did when I was there.
I was active as a predental student, by being on the PreDental Society Eboard, Volunteering in the dental school for 4 years, and even talking to Admin (Including Dean Rouse, Dr. Skinner) on a regular basis. Im saying all this to say, going to HU for undergrad is as well and good, but when I applied fro teh dental school I wasn't even granted an interview even when I had a competitive application and a social advantage...
Take home message, don't think just because you attend HU for undergrad, you are a sure in for their dental school.
