It is true that dental school applications decreased signifigantly during the last decade.
That is not to say that certain regions or schools are not experiencing a higher appliation rate.
For instance, my undergrad had less than 20 people apply to dental school in a specific year during the early 90s. That number has risen to the point where 140-160 people applied each of the last 3 years. Applications this year are expected to reach 170 students.
As students perceive greater benefits in choosing dentistry over other health professions, applicant numbers will continue to rise. The general good news is that more dentists are retiring each year than dentists are graduating from school. This gives way to greater demand.
I suppose the long and short summary would be that competition to get into dental school will become more competitive, while those in school and graduating from school can expect to have a higher quality of lifestyle once practicing.
BTW, I would certainly say that more is required than a 3.0 SGPA, and an 18 DAT. At least, if it *was* that easy to get in last year, or the year before, or even this year, the benefits of the profession will drive the numbers up soon enough. I don't believe it to be outlandish to theorize that in 5 years, a 3.35 SGPA and a 3.5 GPA, along with a 19-20 DAT, might be below par for admission. Just a hunch.
