Why Purple?

The colour purple is synonymous with dental hygiene, and has been the official colour of dental professionals since 1897 when lilac was first chosen for the emblem of the National Association of Dental Faculties. Purple has long been the trim colour for dental hygiene graduates' caps and gowns and is said to signify compassion, purpose, and inspiration.
