@Mr.Scalpel
I'll quickly respond about my own experience since I now realize you didn't ask for my theories to begin with!
🙂
1. Strong GP Clinical Focus - My program was an exceptional school for producing grads that could go straight into GP practice, but this meant a lot of focus on clinical skills and less of a focus on medical didactics or the practice of specialists. I HATED GP dentistry, and after the basic sciences ended I realized I hated dental school. I quickly began to believe that if I could barely tolerate 4 years of dental, there was no way I could tolerate 6 more years...and very quickly I turned away from OMFS.
2. Very few classmates wanting to specialize - My classmates (for the most part) had little interest in getting straight A's, crushing boards, learning about what exactly specialists did, or talked about doing externships or volunteering with our OMFS department. Had I myself been surrounded by 11 other people wanting to do OMFS, like at UCLA/Columbia, this would have been a large motivator for me to continue to push myself and to learn more about how I could make myself a better candidate.
3. No help from the school on dominating applications tests - My program recommended we take the boards after a 2 week break. There were no specific classes or reviews for the boards, there was no effort made to provide us with study materials. When I compare this to the experience my wife had at UCSF on how they facilitated taking the boards, it's truly shocking. And now that it's the CBSE, the preparation your dental school gives you for the test can vary DRAMATICALLY from school to school.
Again, these were non-issues for many successful OMFS matriculants, but they definitely had an impact on me.
BUT if we're looking specifically at your list? We can make some fairly straight forward decisions.
Worst to Best
1. BU (very expensive, no significant help specializing, horror stories from graduates)
2. NYU (cost prohibitive to ANYONE who got in ANYWHERE else...regardless of specialization or not)
3. USC (cost prohibitive to almost anyone who got in anywhere else...it's only redeemer is that this is a school that would help you specialize...even for me, however, cost is too outlandish)
4. The rest. UIC changed their curriculum quite a bit after I left I'm told (I graduated with a DDS, subsequent graduates had DMD with a transition to CBL) so don't use my personal experience with this institution as it may be outdated.
