This is a superfluous strain and fee for dentists and hygenists. Perhaps this should be a requirement to penalize those former dentists who want to rectify their license revocation and trying to re-enter the profession. Emails and other forms of annoucements should suffice in updating dentists with new laws and regulations. When we obtain our dental license to practice, we also agree to abide by the current denal laws and regulations. This exam would be a redundancy and a disgrace to the honorable oath we take to be ethical and law abiding dentists.
