Could you name a handful?
I stand corrected, SOME schools have it required, while MOST schools highly recommend it.
TUFTS:
Q. Do I need to complete my Bachelor's Degree before enrolling at Tufts?
A. Yes, all D.M.D. program matriculants are required to obtain the baccalaureate degree (from an accredited institution) as a condition of admission before classes begin. Accepted students are also contractually obligated to complete any degree program (MA, PhD, etc.) in which they are enrolled at the time of acceptance. The only exception would be for students enrolled in the 7-Year Joint Degree program with Tufts University School of Arts & Sciences.
BUFFALO:
Applicants must have completed a minimum of 90 credit hours of undergraduate study prior to enrollment in the DDS program, with a minimum of 60 credit hours - two full years - at an accredited U.S. or Canadian college or university completed prior to application. Students are
strongly encouraged to earn their bachelors degree prior to enrollment in the DDS program. Students who will not earn a bachelo's degree prior to enrollment must demonstrate a higher level of academic performance.
STONY BROOK :
It is
preferable that all prerequisites are completed at a four-year college for baccalaureate or post-baccalaureate students. However, a maximum of 60 credit hours taken at a community college prior to your third year of study toward a baccalaureate degree may be accepted.
MARYLAND:
While the Committee on Dental Recruitment and Admissions
strongly encourages applicants to earn a bachelor's degree prior to dental school matriculation, applicants who have successfully completed at least three academic years (90 credit hours) in an accredited university may be considered for admission. No more than 60 of the minimum required credits will be accepted from a community college or junior college. Furthermore, these credits must have been validated (i.e., accepted for transfer credit) by an accredited college of arts and sciences.
USC:
3. Do I need a Bachelors degree to attend USC?
A Bachelors degree is not a prerequisite for admission; however, due to the increasing competitiveness of the applicant pool, 100% of all students accepted during the past nine years had earned at least a bachelors degree. Many had earned advanced degrees.
USC basically sums up what I think about many of the Dental schools, IMO, you will be put at a disadvantage if you decide to STUDY ABROAD and not earn a bachelors degree, and will most likely be questioned during the interview about that.
