I'm currently a student at Tufts. I never interviewed at BU and don't know a whole lot about it other than some conversations I've had with BU students, but I'll try and provide what info I can. Also I think it is necessary to point out some generalizations about all dental schools as there are a lot of people on here who aren't in dental school trying to argue schools based on things they have been told and may not have the full picture. I felt that when I was interviewing every school gave me the exact same spiel.
if you want more patients they will give them to you
Every school you interview with will say that they have plenty of patients and it is never a problem. In reality it often isn't the quantity of patients that is the problem, but rather getting patients that need the procedures you are short on. I know students at many schools who are having issues getting the patients they need to graduate. This can be due to many factors such as the student not being vigilant enough about fighting for patients, faculty members not fighting for students in their assigned practice, and a small patient pool at the school. Patient population can vary quite a bit between schools, but most adjust their clinical requirements so that students can graduate. If you can figure out how many crowns, root canals, etc you need to graduate that is a good indicator of how much clinical experience you will get while in school.
the students and professors were all really nice and awesome
...along with the students and professors at every other school I interviewed at. Since starting school at Tufts there are people I have been even more impressed with and a few I really don't care for. Unless you got a really bad vibe at the interviews I'm not sure this should be a huge decision point.
they teach through a private practice setting
If by private practice you mean students are organized into group practices with a faculty overseeing them and efforts are made to keep the patients within the same practice I think every school does it this way.
They have a point system to fulfill requirements like a root canal is 50 points a cavity is 20 points....
...along with almost every other dental school in the country. It is now trendy to say that your school is considering moving away from a point system to a patient centered system where each student just has to treat their assigned patients to graduate. I have mixed feelings about this.
Tufts seems to be really great at preparing students for Part I's. If you want to be confident going into the exams and not have to do a lot of extra studying or have dreams of being a professional test taker for the rest of your life then that is a good thing. I'm not sure passing the boards is that big of a problem for most students regardless of school. Board prep material from Tufts is supposedly known for being very good and I get a lot of request from people at other schools for the material.
Tufts is also known for having a very comprehensive medical course that deals with medically complex cases and how they relate to dental treatment. I think it may be overemphasized in the curriculum, but my wife felt that she was somewhat underprepared in that regard when she went through dental school.
All dental schools will tell you that they are clinically based (because it's what students want to hear), but when you ask why they usually don't give a good answer. Talking to faculty at Tufts they usually point to the clinical requirements and (ironically) compare them to BU's requirements. Compared to say USC (which has a host of other problems) Tufts requirements are fairly unimpressive.
The two really positive things that stand out in my mind about Tufts (and for all I know are also available at BU) are:
1) How much students are willing to help each other out. Everyone is still competitive and works hard, but people will actually share notes, make google doc study guides for exams, etc. Based on my wife's experience in school I was expecting people to be cutthroat and going out of their way to screw others over. Also, my wife ended up taking her regional exam boards at Tufts last minute and several students and faculty went out of their way to help her find patients. At her school she was going to have to pay a classmate a few hundred bucks to use their backup patient (in addition to paying the patient) and pay a 1st year $500 to assist on a saturday.
2) How well run the school seems to be. With the exception of a class or two (which I think the individual instructors can be blamed for) I've had to deal with very few headaches and the few things I gripe about are the typical things most dental students complain about. When a problem is brought up by students the faculty actually listen and in many cases have made a serious effort to fix it or avoid it in the future.
Keep in mind that whatever school you go to you're going to graduate a dentist and no matter how much experience you get during school it will pale in comparison to the first 6 months on the job.
FYI, there is a class of 2016 student who transferred from BU to Tufts. Would be interested to get her take on it, but I'm not sure if she's on SDN.
