This is the transcript of a witness seminar held at the British Dental Association in March 2012. It records the changes in the roles of Dental Professionals within the United Kingdom from the start of the National Health Service to the present time. The discussion included a wide range of major participants in the politics, management and practice of Dentistry during this time. It is one of a series of seminars held as part of the John McLean History of Dentistry Archive organised between the British Dental Association and the History of Dentistry Unit at King's College London to study the profession, especially since the time of the establishment of the National Health Service in 1948.
