Well, I was in the same shoe. It was a tough call to decide between ucla and uop, but the decision had to be made, ucla.
I don't mean to give you an advice, but rather to share my personal story. Yes, my parents think that the reputation of the school play a critical role when you come out of school and open your own practice. But, they left the decision up to me. Same with you, ultimately you are the one that will be spending the next 3/4 years of your life at the dental school of your choice, so this means it has to be the right one for you.
I also got a very good impression of overall facility and atmosphere at uop in comparion to ucla. but, ucla is building a new simulation lab for our class, and I think things will be much nicer when I start.
There are several factors that were interests of mine, which were the school atmosphere, my family, my boyfriend, and my social life. With all things considered, ucla seemed more accomodating although the extra year seemed somewhat "tormenting".
Anyways, again the ultimate decision has to be made by you after considering and weighing all the options. Afterall, it's your life.
Good luck...
