I haven't started d-school yet but, like you, I've also been thinking about how I'm possibly going to afford the insane cost of my dental education for the upcoming year. I've just starting researching the different loans, and it seems to me that everyone should try for the Federal Stafford Loan. If you qualify for the subsidized loan, the government pays your interest (about 6.8 fixed) during school and for 6 months during the grace period. This is where the gov't looks at your parent's income and assets to see if you qualify for this. If both the subsidized and unsubsidized Federal Stafford Loan aren't enough (which seems to be the case for me and many others), apply for private loans.
If you go to a UC, you can apply for the Sallie Mae UC Health Professional Student Loan, which is great if you can get a co-signer because the interest isn't that much different than the Federal Stafford Loan. The catch is that interest does accrue for this loan while you're in school. I think the best loans out there with the lowest interest ask that for a co-signer.
I'm still shopping around for loans. You just need to find yourself the best deals with the lowest APR percent interest, preferably 0% initial payment fee, best deals (reduction on rates for on-time payments), grace period lengths, start of repayment, etc.
