short answer: none. You'll definitely get good exposure to much of this in NYC programs. But, if by experience you mean "competency," then i'd say they're few and far between. Unless you do a 2-yr program, the 1-year you have in GPR goes by so fast that it's hard to cram all these procedures and achieve competence in 1-yr. I'd say that I got good experience all the above (especially molar endo), but not much bridges.
Between anesthesia, medicine, ER rotations, etc. you find that time fliiiiieeeees by! For me, my limited exposure in the above is mainly because i chose to focus on molar endos, perio surgeries, etc. I ended up tailoring my experience to stuff that I found that I like and tried to achieve solid competency in them. You'll quickly learn what you do and don't like while in these programs. For me, that was pedo! One screaming kid and i was out of the room quick lol.
But to answer your question: VA programs are always a good start. Pts for the most part don't pay, cuz Uncle Sam is footing the bill. And with an abundant supply of pt's, usually you can tailor the program to your needs.
