Hey! Ok, here at WVU the requirements are in the process of changing, but this is as good a 'guestimate' as I can give:
-Operative: You must do a set number of restos (so many class II's, so many onlays etc) before taking a 'performance assesment,' and you must pass all p.a.'s before you graduate. the minimum # depends on the type of filling. For example, you need only 2 class V's to be eligible for p.a. but 5 class II's. We have to wax and cast all of our gold inlays/onlays on our own, and I think we need to do 8 total in/on to take a p.a. Once you've taken all p.a.'s you're eligible for graduation. (confusing, i know)
-Endo: 2 Anterior, 2 Bi's, and 2 molars then a p.a. on any tooth
-Perio: Bazillion prophy/maint (maybe 30?), 3 surgeries (one can be a demonstration surgery) and around 30 quad scale/rp
--Pedo: 5 primary tooth extractions, 10 sealants, 5 SSC, and 10 fillings
--Fixed: 3 bridges, 5 crowns
--Removable: 6 units (an arch counts as one unit) of complete dentures, 6 units of partials
--Oral Surgery: 75 extractions, of which 20 must be surgical or require sutures
--Orthodontics: 1 limited tx case and 10 screenings, plus 2 years following a resident on a complete case
These are the bare minimum requirements for graduation. We also have to do a 'complete tx' case of a level 4 or above patient for a class. We also have to maintain a clinic attendance of 90% or higher to graduate (so you can't just come and do the required work--you need to be in the clinic even if you're through)
I am a 3d year who started in the clinic in May. So far, I've done--
2 endo cases (start a 3d on Monday), 8 or 9 fillings (various types), 1 crown prep, 50 extractions (i was on oral surgery rotation early), 1 peds extraction, maybe 8 quad of scaling/rp, demo'ed a perio surgery. I've also got a patient healing from extractions who will begin complete denture treatment in a week, and a patient coming in later this month to take impressions for upper and lower partials.
I hope this helps!
