I believe the current regulations as set by the board and passed into law protect the health of the public. Procedures performed on patients should be done by practitioners who have actually practiced said procedures in controlled settings - lab through simulation and clinic under observation of a licensed dentis, this is important to public health.  As I stated on the initial petition for rulemaking, a dentist would not be allowed to perform procedures without having first performed simulation procedures and then under observation in clinic during 3rd and 4th years of dental school...and the same with hygienists and their abilities to perform scaling and root planing or dental prophylaxis.  These licensed professionals require education and training prior to performing procedures....dental assistant II must comply with the same practices.  Grandfathering assistants into the DAII registration is acceptable with documentation that meets current standards.
