Objective: This paper reports the results of standardised clinical caries examinations of 170,731 5-year-old children from across England and Wales. These 2001/2002 co-ordinated surveys are the latest in a series which seek to monitor the dental health of children and to assess the delivery of dental services.
Method: The criteria and conventions of the British Association for the Study of Community Dentistry were used. Representative samples were drawn from participating health authorities and boards and caries was diagnosed at the caries into dentine threshold using a visual method without radiography or fibre-optic transillumination.
Results: The results again demonstrated a wide variation in prevalence across Britain, with mean values for d3mft for the current English Strategic Health Authorities (SHA) (of the National Health Service), Wales and British 'territories' ranging from 0.75 in Jersey and 0.84 in Kent & Medway to 2.73 in Gwent and 2.47 in Greater Manchester. Mean d3mft across England and Wales was 1.52 (d.t = 1.11, mt = 0.20, ft = 0.20). Overall, 40% of children had evidence of caries experience (d3mft > 0); the percentages ranged between 23% (Jersey) or 29% (Essex) and 61% (Gwent) or 54% (Greater Manchester). The distribution of caries was highly skewed. Thus the mean caries experience for those with disease in England and Wales was 3.83, as opposed to the overall mean of 1.52. Trends over time demonstrate slight increase of 3% in overall d3mft for England and Wales since 1999/2000, compared to the 4% improvement seen for the two previous years. Of the three components of dmft, d3t and mt have increased while ft has fallen. The care index has also fallen (13.2% in 2001/2002, compared to 14.3% in 1999/2000); SHA/country percentages for 2001/2002 ranged from 8-29%. This indicator has not, however, regained the levels seen in the past.
Conclusion: There has been no improvement in the dental health of 5-year-old children. Overall, the provision of operative care for those with dentinal decay has decreased slightly; significant groups remain within the population of 5-year-old children who have dental disease and who are in need of dental care.
