Someone please feel free to correct me if I am wrong, but it was my understanding that in order to become a licensed dentist you need to take a licensure exam such as the ADEX or WREB. These licensure exams test the "hand skills" of graduating students in order to make sure they are clinically competent to practice dentistry.
Roseman's graduates have become licensed dentists. Therefore, they were able to pass the standardized clinical exam that make sure they were competent to practice dentistry. I don't think anyone graduating from Roseman should be concerned that their "hand skills" are not up to par when they are passing the same exams everyone needs to take in order to become licensed.
