I am writing concerning the propposed Regulatory Action requiring a dental jurisprudence exam.  I believe that all initial licensees should be required to pass the exam prior to licensure.  I feel requiring licensees to repeat the exam every three years is a burden that is being forced on the backs of 95% of the licensees that abide by the laws of the commonwealth, and are paying for the sins of repeat offenders.  I feel the Board of Dentistry to should keep licensees informed of changes in regulations, and interpretations of the regulations through e-mail newsletters.  I would be interested to know if the Board has looked at other states to see if three year testing has greatly improved licensees compliance with the law.   I know the Board has a thankless job and I appreciate their efforts to protect the citizens of Virginia.  I feel that timely communications will go further to help us remain compliant rather than a test every three years.  To illustrate the importance of communication, I learned about this regulation only through our Virginia Dental Association leadership.  The average dentist and hygienist are unaware of this proposed regulatory action.  All licensees should have been informed by the Board before the comment period.  Communication always inproves governance.
