haha, wait until you are taking the written part, a requirement for residency graduation, of the endo board and then the oral part of the endo board if you want to become board certified, like i do. all non-sense memorization. typical question of the written part: in 2010, John doe did an experiment on rats to learn about X, what did he find..so stupid.
NB: in endo research, John doe's study in 2010 might have contradicting results to that of John smith's in 2012. in addition, John Doe's study in 2010 might have contradicting result to another of his study in 1998. To be an astute endodontist by ABE standard, you need to know the author name, the result and the year, if you have energy...all can be googled easily these days
No offense, dentists try prove that they are just as smart as the physicians, by memorizing random craps like how many times does an average human being swallow per day
