Hong Kong Dental Association Hong Kong Dental Association (HKDA) was founded in 1950, formerly known as Hong Kong Dental Society. The Association representing >90% of the registered dentists in Hong Kong, with a membership in excess of 2000 members. Since its establishment, the Association has encouraged and provided opportunity for lifelong learning and enhanced professional skills and standards amongst its members. The Association is recognised as the representative organisation of the dental profession by the Hong Kong Government. In the 1950s and -60s, when dentistry was not yet fully developed in Hong Kong, the Association advised the Hong Kong Government on, for example, water fluoridation, the setting up of what is now the Faculty of Dentistry of the University of Hong Kong and creating a training school for dental hygienists. The Association’s, distinctive, bright yellow tie with HKDA woven into the material of the tie, is unusual amongst dental ties in being monochrome.
