title: The relationship between children's dental caries experience and the prescription of general anaesthetics. an evaluation of the effectiveness of a Personal Dental Service Pilot.
abstract: OBJECTIVE
  To determine if there was a high correlation between the prescription of a general anaesthetic for dental treatment in young children by a Personal Dental Services (PDS) general anaesthetic pilot and the dental health of children at a ward level.
  
  
  METHODS
  Postcode data from an audit of the single dental general anaesthetic provider in an area was extracted and mapped to individual wards. A proxy for the oral health population was obtained by using the results of a large-scale dental prevalence study of five-year-olds. The wards were ranked into quintiles by dmft and a mean dmft calculated for each. There were 1,406 patients who had a general anaesthetic, 74% were aged 11 years or less.
  
  
  METHODS
  A personal dental service dental general anaesthetic pilot in the north of England providing services for a population of approximately 300,000 residents in a non-fluoridated area. RESULTS There was a positive correlation between increasing levels of dental decay in the population and increasing intervention ratios for dental treatment under general anaesthesia (r2 = 0.90).
  
  
  CONCLUSIONS
  The PDS pilot provided dental care under general anaesthesia for more patients from wards with poor dental health than from wards with better dental health.
