Just relax, and be yourself. The questions are all really straightforward (just the typical ones that you'd expect). The interview is mostly conversational, with a faculty and a student both asking you questions.
For the rest of the interview day, one suggestion I would give you is to dress warm and comfortably. There's a lot of walking involved (both inside the dental school building and outside around the campus), so be prepared for that.
Lunch is provided, and actually pretty filling so that was pretty nice. The student tour guides are all friendly, and you can ask them any questions you might have. They provide you with a notebook to take notes in so you don't need to bring anything with you unless you really want to
Feel free to ask if you have any other questions
