There are sections for awards/honors/scholarships, DAT scores, dentistry experience, extracurricular/volunteer/community service, research experience, work experience, and then all the basic info (biographic info, parent/family info, high school, coursework, etc).
Edit: Oh, and in the background info section there are a few short answers...manual dexterity experience, do you have any relatives in dentistry, did you do any academic enrichment programs (ie. post bac, summer programs), have you been expelled, have you applied before, have you applied to other health professions beside dentistry, and has your education been adversely affected by anything (ie. if you had a long term sickness and failed a class).
