I'm a D3 at ASDOH. While the module system is nice at inflating your grades, it makes a little harder for you to retain the information for boards. However they give you 7 weeks off in between D1 and D2 year to study for part one so you have plenty of time to prepare. The sim clinic closes at 5pm everyday which is nice so you don't have to stay late, bad in that it's harder to get time in to practice. Research is scarce at ASDOH. However they'll send you to another dental school for the summer to conduct research. I spent 6 weeks at Baylor this past summer doing oral cancer/salivary diagnostics research. We do a lot of public health at ASDOH. Some like it, some hate it, but I'm getting my MPH so I don't think it's too bad. Clinic is pretty cool, I feel like I'm getting a good experience. We don't have a shortage of patients and my patient load is finally at the point where I'm busy everyday. Also, we do very little lab work here. Aside from custom trays, occlusal rims, and maybe the occasional wax up for an onlay, you don't have to do much lab work. Lastly, during our fourth year we spend half the time away at external rotation sites across the US. This is pretty awesome because you get tons of experience. Overall I'm pretty happy that I go here. I would choose ASDOH again in a heart beat, and given your 3 choices I think it's the best.
