Orthodontics is the branch and specialty of dentistry concerned with the supervision, guidance, and correction of the growing or mature dentofacial structures and the diagnosis, prevention, and treatment of any abnormalities associated with these structures.
The NDSE in orthodontics tests a candidate’s knowledge and clinical competence in orthodontics at the specialty level in Canada.
