I can't speak for those now. My AEGD was at Great Lakes some time ago (2001), but I don't think its changed much.
Rotate through each specialty for 2 months (endo, perio, oral surgery, prosth). One month you work in the am with a specialist/operative in the pm, the other month your work operative am/with specialist in the pm. This was Mon-Fri. Thursday is usually field day (clean house) in the Navy, so we did Lit reviews or had lectures on those days. You will be on duty (on call), but how often depends on how many LTs or LCDRs. We had a ton of guys, so were only on duty 1-2 days/month. We had to stay till 8pm on weekdays and till noon on weekends, depending on # of emergencies. You had to be within 1 hour of the base when on duty.
Days run 7-4. Arrive early, officer's call at 7am (you don't show up late for this). Start patients 8-11:30. Lunch 11:30-1pm (lunch + PT). Patients 1-4pm.
With endo; Hand file first few cases, then graduate to rotary-it may be different or all rotary now. I did/assisted on 2 apicos, the rest were just RCTs.
Oral Surgery: Mostly was 3rd molar ext's. Assist oral surgeon with first one, he assisted me with second, I was on my own by the third one. Did about 3-6 cases per shift, no sedation, just cover their eyes and go.
Perio: Mostly did a ton of S&RP, assisted a few surgeries, and did 2 CT grafts with periodontist assisting. Know your literature and perio bugs.
Prosth: Did a lot of crowns, maybe 1 bridge, a few RPDs/flippers, no dentures there as the population is mostly recruits.
Operative: Sling amalgam, MODFLs (aka WFTs), had a lot of new dental techs so lots of OJT for most there.
Hope that helps.
