Absolutely. I'm <3.0 but there are reasons for it. My DAT wasn't bad, and on par with other matriculated applicants. My low GPA was explained in my PS and my upward GPA trend corroborates. I also have other strong aspects of my app that other applicants don't have.
There are applicants applying after their sophomore year with high GPAs, but with only about 60 credits. I'm applying with a much lower GPA, but with ~200 credits. But when you look at my last 120+ credits, I'm on par or above the applicant like the rising junior in my example. But I got off to a very rocky start and dug myself into a very deep hole.
Every applicant and every school are different, as well as how they choose to look at the applications. My example was just one of many many scenarios. That is why a holistic review really is required.
Think about the other end of the spectrum: how about the applicant with a very high GPA, a high DAT, and absolutely nothing else extraordinary in their application as well as a terrible interview. This indicates that the applicant is an outstanding student, but that doesn't necessarily mean that they will be a great, or even a good dentist.
Back in the 80s dentistry was very unpopular and schools were shutting down due to lack of applicants. Competition was low and people were getting in very easily. They were not nearly as competitive as the applicants today. But that's not to say that there aren't some damn good dentists out there today that graduated during that time frame who were admitted with unremarkable scores. My own mentor said that he was a solid "B" student, and he would've never gotten into dental school today. But he is a remarkable dentist and incredibly successful.
Holistic review is key.
