Preventative Resins

Added to Handbook: Prior to June 2004
Updated: September 2013

PURPOSE

To provide guidelines on the provision of preventative resins by dental hygienists.

BACKGROUND

As stated in the Scope of Practice Statement, dental hygienists may apply preventative resin materials. The resins used for preventative resins are of a similar composition to the composite resins used for pit and fissure sealants. The management and application techniques of both materials are similar.

However, tooth preparations for fissure sealants and preventative resins differ. To prepare a tooth surface for a sealant, the surface is cleaned and an acid etchant is applied to create retentive micropores. When the dentist prepares a tooth surface for a preventative resin, a preparation is cut into the tooth surface using a bur or an aluminum oxide air abrasion system. As stated in the Sealant interpretation guideline, aluminum oxide air abrasives cut hard tissue, which is outside the dental hygiene scope of practice.

POLICY

Registrants may apply preventative resins on a tooth surface that has been prepared by a dentist, provided that appropriate education has been completed. It is not within the dental hygiene scope of practice to diagnose or remove decay, as both of these are restricted activities that fall within the scope of practice that applies to dentists.
