Perfect Applicant is
GPA = 4.0 or higher
sGPA = 4.0 or higher
DAT = 30/30/29 <---because a little imperfection, is perfection
Extracurriculars = shadowed every days since 5 at every specialty and general practice. Volunteered in both dental and non-dental ways for last 10 years. Hand built a dental clinic in Malaria-ridden Island off African southwest coast and convinced 10 outstanding dentists and specialists to move out there to provide free dental care.
But seriously...there is no perfect applicant. Schools look for students who, yes, are academically adept (and what that means for every school has slight variations since some schools weigh DAT > GPA and some care more for GPA, and some look more at school you attended or difficulty and scope of science courses you took, etc.). However, schools completely vary on the rest of what matters to them. The perfect student for UOP may never have done any research, while the perfect student for Harvard may have published 8 papers in the lab of a Nobel Prize winner. The perfect student for UW may be a student who has residency in Washington, while the perfect student for UNLV may be a BYU graduate. Each school is looking for someone who fits their school, and you can't be everything to everyone.
If all you're looking for is a bland generalization of a "perfect dental school applicant to apply to ANY dental school" then I think the best answer you can get is something like:
1) Get's straight A's or close in all classes
2) Shows an interest in at least one other school subject other than science
3) Has taken or done some kind of work that exemplifies hand-eye coordination or fine manipulation
4) Scores very high (above 20s) in all sections of DAT
5) Has shown leadership qualities (not just taken leadership positions) in both school and outside of school.
6) Did some form of research with undergraduate professors in professor's research labs
7) Has done 30+ hours of shadowing and or volunteering at dental clinics or offices
8) Has an upbeat personaility and strong conversational skills.
I mean, we could throw in arbitrary numbers and names of hobbies and subjects, but what exactly is the point?
