Outcomes and costs of pre-school and school-based fluoride varnish pilots.

Objective Fluoride varnish (FV) applications reduce the risk of dental decay in research trials. These pilots were conducted to test the feasibility and costs of providing FV applications in schools. Changes in dental decay levels were also monitored.Methods Data were collected on the proportion of children with dental decay, mean number of teeth affected and whether the child had attended for dental care. The cost of delivering the intervention was calculated.Results More children were reported to be attending for dental care by the end of the pilot than at the start. The proportion of children with dental decay and the mean number of teeth affected increased, but more children seemed to have received treatment. The intervention cost about pound88 per child per year, with most of the costs due to the intensive efforts needed to recruit and maintain participation in the pilots.Conclusions Establishing community FV programmes requires significant investment and the long-term benefits in practice are unclear. If dental decay levels are to be reduced, there is a need to improve diets, alongside fluoride strategies. This may be best achieved by integrating oral health improvement programmes into other health programmes, particularly sugar-reduction strategies.
