Agree with the statement above to a point. A dental school without an OMS residency may put you at a slight "experience" disadvantage but I know folks that overcome that. It's always a very unique caveat to dental schools without specialty programs. As a student you get to do more procedures but less interesting procedures and the exposure the entire specialty is certainly limited. In the OS clinic of a "Creighton" type school you will pull teeth and do some biopsies and may assist in some other more complex office procedures. You will not have access to a full scope OMS clinic that manages TMJ, Large benign or malignant path, large volume orthognathic surgery, trauma, etc. But externships really help out with this if you can get them with the 'VID. There are exceptions of course, but those are exceptions.
As the OMS PD at Minnesota I can give you exact numbers of my students who have matched over the last few years. Up until the last few years students at struggled to match but for the last 3 years all that have applied have matched. That is a very misleading statistic in general as dental student classes vary so much from year to year. Some years the students who I think would succeed have no interest and some years there are students who are very interested but I know they will not make it. So who knows. Do your best, work hard and extern with us when you are 3rd year. Come see what our program offers.
