i don't know about the smaller schools, but the dental schools generally know about the reputation of larger schools. For example, i'm attending Cornell, and during both my Stony Brook and Columbia interviews, a key point of emphasis in both interviews was the fact that Cornell is an extremely competitive school, and having had the experience of going through an ultra-competitive environment prepares me well for dental schools. I think that definitely strenghtened my interviews and their overall impression of my credentials.
