i know of my friend who got into dental school without interview but that was because he was on automatic admission program where you have a contract with your undergrad and dental school (i think you had to keep at least 3.3+ GPA and 19 on your DAT). but they do interview you during your undergrad to get into that program, so i guess it depends on how you look at it
i also see there were couple of people on TMDSAS statistics that some of them had no DAT scores but it could be simply because of errors or again it could have been some kind of special program.
i dont think you can apply to dental school and get in w/o interview or DAT, if you're applying in regular AADSAS / TMDSAS ways
