Point of Clarification,
If you haven't taken the DAT prior to the submission of your AADSAS, you do not send your new DAT scores to ADEA (AADSAS)! Your new DAT scores will be directly forwarded to the dental schools that you specified on your DAT application/registration (first 5 dental schools included in the testing fee and $10 for each additional dental school) processed by ADA Testing Services.
Put it simpler terms, once you submit your AADSAS, later AADSAS do not want your DAT scores, send your DAT scores directly to dental schools and you request them with ADA Testing Services (DAT registration people).
I hope I didn't confuse anyone. 😎
