I would recommend you study each section independently...
Microbiology - Decks should be sufficient by themselves for review. Do lots of back questions! They tend to repeat a lot of micro.
Physiology - There arent too many questions on Physio from my experience. Learn the decks, look over all the systems in your texts.
Gross Anatomy - Study netter in and out. Know nerves, blood vessels, musculature, skeletal anatomy really well. Some people get more questions on blood supply, some get more nervous system... it varies. If you know Netter, you will be good to go. Usually its the hardest subject on the Boards, spend lots of time with it. Dont rely on just the deck's or practise exams/questions for this section.
Dental Anatomy/Occlusion - Take your study teeth out, memorize every line angle. Know characteristic features of particular teeth, which ridge is longer where, which teeth tend to be missing most often etc etc. Know your pedo anatomy well. They key to this section and especially occlusion is LOTS of practise. Do as many questions you can find. Dig up your old Dental anatomy finals or midterms, and redo them. Temple provided us with a stack of practise questions, which were pretty detailed. The actual Boards questions were way more simplified (did not ask specific teeth numbers when referring to occlusion).
Pathology - Decks are a good start. Not too many questions on the boards, but know the most commonly asked questions well. Do lots of practise questions.
Biochem - I didnt use the decks at all for this section. My best advise is to review your old Biochem notes or a Board review book that you have and know all the CYCLES and Pathways. Dont memorize the words, try to understand all the cycles and pathways well. Draw them out! Krebbs, Gluconeogenesis, etc etc. Be able to recall the cycles instantly. When I started the exam, I used my provided pen and paper to jot down all the cycles (in a simplified form) so i can use it as a reference for later.
My advice for when you take the exam... dont look at the answer choices right away. Try to answer the just question in your head and then look at the choices provided.
There are always some people who arent interested in specializing that just want to pass, so maybe all this extra effort is pointless. Thats just not the right way to go imho. I say that you set your goals really high, and aim for the sky! I scored pretty high on P-I, even surprised myself.
