I strongly oppose this needless regulation.  It is the classic use of a sledgehammer to hit a pin...punishing the masses for a few who do not abide by the law and will not even with the added burden of an exam every 3 years. If you feel you have to do something make the exam elective and available on-line free-of-charge for those who would like to test their jurisprudence knowledge.  Where do you even come up with a $50 fee?  Are you looking for ways to generate revenue in this already highly regulated and over taxed society?  Enforcing this program will also turn into a nightmare.  You will now be reviewing cases of those people who are practicing dentistry who failed the exam or were delinquent in taking it.  Consider the unanimous opinions of those who have commented and nix this burdensome proposal.  Thank you!
