For the most part yes, but you are in only one place during those 3rd and 4th years; the free/reduced clinic. Some schools will throw into the clinic starting week one of your first year. Just different techniques.
With MOSDOH you are based in St. Louis but will move around to different Community Health Clinics through out the Missouri area. After my interview, I checked where the clinics are located and although one of the common links is poverty, certain areas are plagued with various diseases. The moving around will not be ideal and be a huge stress, but it will forge some of the best clinical dentists.
