6. I just renewed my license in August 2018. Why does it only give me 1 year for the expiration?

              -The new rule goes into effect September 1, 2018. If you renew after that date it will reflect 2 years and the 24 hour CE requirement.

7. The assistant doesn’t need to be trained in polishing and sealants, right?

              -There is a lot of confusion about this rule.

As of March 10, 2018, the Dental Board put rules in place that an assistant has to be trained by CODA approved 8 hour course in sealant placement and coronal polishing. Other requirements are:

                       1). Graduate from an assisting program,

                       2). Received certification of completion by the specified Dental Assisting                               National Board and approved by the board.
