This is important... DO NOT DO THE DDS/PHD UNLESS YOU REALLY LIKE RESEARCH AND WANT MORE EDUCATION. Yes, getting the dual degree helps your chances a lot, but you're putting in 3 more years of hard work and won't be guaranteed anything (could turn out to be useless when all is said and done). Besides, you'll still have to do reasonably well to have a shot at any specialty. And, you may end up deciding you don't want to specialize after you're through. So, don't go for the dual degree track just to increase chances of specializing. If your goal is solely to specialize, just work your butt off during dental school, and do some research on the side to beef up your application. Plus, doing the dual degree will affect your class bonds, since you'll be with one group of students for a few years, get separated, watch them graduate, then join another group of students. Just make sure you think it through thoroughly...
