Plan on 8am - 5pm every day. There's lots of holes in there -- some days you go home early and some days you have a lecture from 8-9 and then nothing until 3pm -- but everything is usually scheduled around those times.
You will have a comprehensive final exam on the last day of the semester with a week-long reading period beforehand. Expect an exam or two every week for the last month - month and a half of the fall semester.
Spring is similar but more time is spent in lab (single tooth restoration).
I'd send you my schedule but I've color-coded the bejesus out of it and it wouldn't be accurate.
