Interpretation Guidelines

May 5, 2020 Update: This section contains a series of guidelines that are intended to explain aspects of the Dental Hygienists Regulation and Scope of Practice. The College recognizes that some contain language previously used under the former regulation and a review is currently under way. These guidelines remain in place at this time; however, they need to be applied in the context of the new Dental Hygienists Regulation and CDHBC Bylaws. Readers are welcome to contact the CDHBC office if they have questions about the application of these Interpretation Guidelines in the interim time.
