One from UCSF applied this year.
There has been a Harvard person for the past 2 years, so I suspect that there will be one again this year.
The Cloister program has been very active trying to get more dental scholars into the program, and I actually think that the interview is the most important gatekeeper here.
As long as you have strong grades and past score history, and the 3 letters of rec and the Dean's letter are strong, you'll most likely get an interview.
And it's pretty much 1 out of 2 by that point!
