I actually chose from the opposite viewpoint. I chose a school with zero specialty programs because I felt that way my undergraduate clinical experience would be superior. For example, at our school, none of the molar endo gets sent to the specialty residents. As long as we are capable, we get to do the procedures that would normally be siphoned away from the undergraduate student dentists. I have talked to people who didn't even have to do molar endo at their school because it all went to the residents. I feel a school with no specialties gives you a broader clinical experience.
Just a thought.
