Classes of Registration

There are three categories of certificates of registration with CDHO:

General – applies to those dental hygienists who meet the basic registration requirements; all registrants are initially registered in the General category.

Specialty – applies to registrants who hold a General certificate of registration and who have completed a program in restorative dental hygiene that meets the requirements of the College.

Inactive – is usually held by registrants who are taking some time away from practice. A CDHO registrant with an Inactive certificate of registration cannot practise dental hygiene in Ontario.
