obviously OP was wondering whether DS views him/her as a minority, which would give bit of advantage in regard to dental school admission. and the answer again is No. It goes same with Asian people not being counted as minority as far as dental school admission goes.
Yes, I am fortunate enough that i grew up with parents who do have bachelors degrees. But OP here isn't even talking about that. OP was asking whether he/she would qualify as a minority for dental school just because her parents were born outside of U.S.
If OP was born outside of U.S., it would make little bit more sense. But just having parents born outside of U.S. to qualify as minority? I don't think so.
