I asked this question to many prehealth advisors and teachers and got a whole range of responses. Some people told me if I felt comfortable submitting the same PS then it would be fine. Yet others told me to rewrite the whole thing because obviously it wasn't working before and why take the risk of adcoms figuring out I used the same thing. I would defn at least revise your PS if not rewrite the whole thing. I ended up doing a complete over haul on my PS and I have to say I felt a lot better after that because I knew I tried really hard to make it the best essay possible. I think I used less then two sentences from my last one. Surely you have improved your application in some way over the past year, had new shadowing experiences, or have a new perspective on the field of dentistry and why you want to enter the profession. Don't regret not changing your PS and then kicking yourself for not doing this! It's a pain in the a** but then again it could make a big difference in the outcome this time around. Best of luck
