Yes. You can use the same personal statement.
If I could give you some advice on your political approach to your application. I know that you have probably worked extremely hard to get to where you are in the application process. However, there is always more to be done. You need to remember that you're stuck in a sea of applications that look almost identical to yours. Whether or not you are re-applying for 2007, you could strengthen your odds of being called for an interview and for being accepted by paying more attention to your political approach (understanding that you may have already focused on this).
Don't underestimate the power of the people in administrative positions at many of the dental schools. MANY OF THEM, have the power to grant you an interview (they may not make the decision to ACCEPT you, but many can put your file in the, "invite for interview" pile. Make friends. Call A LOT. After EACH TIME you talk to a receptionist etc. sit down and write a short letter thanking that person for being so very kind and explain how it isn't always easy to get answers. Make them feel important. The most important thing...repetition. Do this over and over and over and...you get the point. YOU WILL STICK OUT IN THE CROWD.
If you can, find someone to talk to at EVERY school. If you end up re-applying, it may be a blessing in disguise.
Lastly, DON'T GIVE UP. People like me have put down deposits at many schools to buy more time to make very important decisions. I will be sending out letters to schools tomorrow that will free up seats at the schools I have decided not to attend. There are many people out there that have done the same. There are still seats to fill, you just may not see them yet. People get accepted even up until the the first week of classes. Let me repeat, DO NOT GIVE UP! Do not counsel with your fears. I remember a sign that was on the window of the testing center when I took the DAT, 95% of all failures are due to fear, not underpreparation!!! You will get in! 👍 👍
Good luck and God speed!
