Kaplan lecture notes is a huge book, and in my opinion it's awesome to study when you need to strengthen your basics. If you graduated a while back or if you feel like you don't remember the anatomy you learned through dental school i would highly recommend this to you.
Dentessentials is a concise review but you need to have a solid background in order to understand it, since there's not sentences to read, just tables and diagrams. So i think this is not enough to study for the boards.
