"Dental schools participating in AADSAS will report to AADSAS by April 1, the names and identification numbers of candidates who have paid a deposit and/or hold a position in their entering class. After April 5, AADSAS will report to each institution the names of candidates in their entering class who are holding acceptance(s) at additional institutions. Dental schools will have the option of rescinding an offer of admission to candidates who have paid deposits and are holding positions at multiple institutions. Dental schools with candidates holding multiple positions on April 1of the year of admission will give such candidates a minimum 15-day notice if they choose to withdraw them from the entering class."
Thanks for the information, I never looked into this before!
