Here are some of the highlights of UCSF. You should weigh this aginst Univ. of Pacific and see which one looks better for you.
You may already know this but if you don't here they are
UCSF:
Among Cali. dental schools, UCSF has the best ratio of students to faculty.
ADA ranks UCSF the best for clinical productivity among all public dental schools in the US and number two among all dental schools in the US.
UCSF ranked first in NIH research funding among all US dental schools.
Thousands of patients visit the UCSF dental school every year.
While the Gourman report is barely considered reliable when it comes to ranking dental programs, the last time dental schools were ranked, UCSF came in at number 2 behind Harvard. The Univ. of Pacific came in at 30. Even other Ivy League Schools are ranked below UCSF. Now keep in mind, this ranking should not be the only factor in choosing a school, but if you are indifferent on all the factors, may be this will tip the balance.
Good luck and I hope this was of some help.
