British Association for the Study of Community Dentistry (BASCD) guidance on sampling for surveys of child dental health. A BASCD coordinated dental epidemiology programme quality standard.

The British Association for the Study of Community Dentistry (BASCD) is responsible for the coordination of locally based surveys of child dental health which permit local and national comparisons between health authorities and regions. These surveys began in 1985/86 in England and Wales, 1987/88 in Scotland and 1993/94 in Northern Ireland. BASCD has taken an increasing lead in setting quality standards in discussion with the NHS Epidemiology Coordinators of the Dental Epidemiology Programme. This paper comprises guidance on the sampling for these surveys.
