Improving standards of dental health and greater awareness amongst the general public of the potential of dental treatment, including orthodontics have led to an increase in the number of patients seeking orthodontic advice. Yet there are insufficient orthodontists in Britain to meet the population's present need for orthodontic treatment. Moreover, the improved results expected from patients and professionals has led to an increase in the use of fixed appliances, which are more demanding of orthodontists' time. Despite attempts to rationalise treatment provision, the present number of British orthodontists remain unable to meet the need for treatment. This is indicated by the length of waiting lists in all branches of the service. Since there are no plans to expand the orthodontic profession, the present discrepancy between need for treatment and provision of treatment will not be resolved in the foreseeable future. 2. The orthodontic societies support the development of existing training programmes, career pathways and salary structures for dental surgery assistants, dental therapists, hygienists and technicians. Suitable courses need to be developed for people who have had a career break and wish to return to work. New courses also need to be designed for people entering training programmes in later life from a variety of backgrounds. Funds need to be identified in order to provide continuing education for all grades of ancillaries. 3. The development of a 'post basic' Training Course in Orthodontics for qualified dental surgery assistants is commended. A nationally approved certificate of training should be given to those who successfully complete a recognised course.(ABSTRACT TRUNCATED AT 250 WORDS)
