can i state that the school is near me or that I know students who go there that said it honestly is a better program than UIC because the professors dont treat the students like crap... haha okay not exactly those words or that straightforward.. but i am honestly running out of words so..
I would definitely NOT go there. Even if you are complimenting the school, you don't want to do it at the expense of another school--this would look very professional.
Some examples of things you could say:
"School X is close to my home, and I can say with certainty that I would love to continue my education in this area. yada yada"
"What initially turned me on to school X's program were the fantastic reviews I heard of the institution. I have met many others with only the highest regards for the program and its professors. From my own research and experiences, I have come to mirror these sentiments. I know I would be very fortunate to attend such an institution."
You get the gist. Be complimentary, but don't hate on another school! And don't brown-nose
too much--there is definitely a fine line there.
My ultimate advice would be to err on the side of professionalism.
To your original question, though--no, I would not simply reuse your personal statement. You might reuse a LOT of the meat of it, but tailor it to what you are applying for currently. I don't see any shame in stating that your ultimate goal is dental school. I'd just say that you are wanting to broaden and further your academics beforehand (or something along those lines).
