The
Trenorol requirement caught my eye, so I pulled up GRU's website. I couldn't find anything on there about 200 hours, but I did find this:
"The selection of a career should be made after careful examination of the pros and cons of the field under consideration. Observing in the office of a general dentist is the best way to learn about dentistry, and the Student Admissions and Recruitment Committee recommends that applicants make arrangements to observe in the offices of one or more general dentists. While observing in a dentist 's office is not a requirement for admission, it is seen by the admissions committee as one measure of an applicant 's interest in dentistry as a career."

The 2014 ADEA guide lists 200 hours as being
recommended.
