How would it be on the record? You mean as an expulsion and then being asked why? I don't think transcripts list reasons for academic judicial action or stuff like that, right...?
But regardless, that's one thing dental schools all agree on: they're rabidly against academic dishonesty. There's basically two ways to get expelled from Buffalo: making fun of your cadaver and cheating. (If you fail, they desperately try to help you and keep you on.) This is the same across dentistry since it's such a trust-based, peer-driven field. I imagine academic dishonesty would be more serious than a criminal record, from what I've seen of their priorities.
