Abstract

BACKGROUND:

Dental caries is a public health problem. Fluoridated milk (FM) schemes are used as a preventive measure. The impact of process variables in these schemes is not understood.

METHODS:

Process variable data on the number of days of consumption, attendance, volume consumed, parental consent together with the proportion of children drinking FM at 7- and 11-years old were aggregated from eight schemes in the UK. The impact of process variables was modelled in an 'averaged' scheme (reduced in effectiveness by process variables) and compared with a notional 'ideal' one in which no process variables operate. Parental consent was analysed according to socio-economic groupings.

RESULTS:

Proportion of days per year FM was consumed: 0.52. Values for process variables were: attendance rate 0.94; proportion of milk consumed 0.91; proportion of children with parental consent at 5 years 0.65; proportion drinking FM at 7 and 11 years respectively 0.54 and 0.27. No clear trends were observed for parental consent across socio-economic groupings.

CONCLUSION:

Modelling suggests that due to the cumulative impact of process variables, there is cause for concern about the effectiveness of FM schemes as currently managed in the UK as a standalone public health measure for the prevention of caries.
