no one can tell you whether you are going to get in or not.
but people here will tell you whether you will have a good chance or not.
as far as your GPA goes, it's about the average of accepted dental students (not applied students). some schools have accepted median around 3.7 and some have 3.3 but it usually falls in between those two.
for DAT, the usual accepted average is around 19. UoP for example has median around 20 and 21 for PAT whereas most of other schools have average around 19.
so numbers above are statistics for two factors of getting into dental schools. you have an average GPA (it'll also depend where you went for undergrad, not too much but slightly) and your DAT is far below average. I'm sorry but your percentile with 16 would be very low, since DAT average for every students that take the exam is supposed to be 17.
so with two factors above, i would say try to save your money and retake with much more studying and try when it has more chances. but if you have a really good experience (life experiences such as jobs in health care field, Masters program, lot of curricular activity hours, lot of dental experiences, and etc.) then those can always boost up your chances and really good LORs will always help too
reading from your posts, it seems that you're not too good with english (at least grammar wise) so maybe you want someone to carefully read your personal statement and etc.
your chances are slim and if you still haven't applied yet, then i will say that you're chances are really low. it also looks like that you have not done too much research about applying to dental schools (from seeing you asking about the residency and etc.).
i would suggest you to take your time to research more (find out which schools have accepted students with low DAT or Asians) and try to apply ASAP when next cycle comes up (which would be May 1st of 2009). also don't forget to study really hard for DAT. i'm not sure how much effort you have put into studying for DAT, but I truly believe good DAT scores can be achieve by anyone who puts enough effort into it.
also, please do not let your parents' pressure decide what you want to do. it sounds like you're about to graduate from college, and not everyone that gets into dental school goes straight from college to dental schools. some people do take their time to prepare better and it definately helps them to decide what they truly want to do and also prepare for the dental school itself
good luck withe everything and if you have enough money i guess it wouldn't hurt to apply (but remember, if you do not get in, you have to explain to schools how you have improved yourself from the first application cycle)
