I know this state was not in your list but since you were essentially in the New England area of preference, I thought I'd toss in Vermont. I'm currently Fletcher Allen Health Care, the only GPR in Vermont. It's kinda early in the ball game but I'm really optimistic about the place. The dental community is very well knit - "one for all and all for one" type of thing. It's a level one trauma center so there are surgeries up the wazoo...and YOU basically are the "oral surgery resident" there. Looks like you can learn a lot coz the Chief of Medical Staff is an oral surgeon (does a lot of TMJ, Orthognathic, LeForts, BSSO's in which you scrub in and do a lot!). MOST importantly, the GPR residency director is awesome, he's a site accreditor for GPR programs around the northeast...and is committed to making sure that more than enough dentistry is done at the clinic (endo, operative, prosth, implant (a couple of placements and a few being restored).
Anyhow, it's a good place...you should give it a thought if you're lookin' into programs in this region.
Oh, I interviewed at Danbury, CT and it seemed pretty good - the staff and faculty are REALLY UBER NICE! Brigham & Women's has a decent program as well...but there's a lot of emphasis on oral medicine...wasn't convinced about some clinical aspects of the program...but again, great staff and you get a certificate from Harvard which might be a good thing to have in certain situations!
Hope this helps.
