A caries preventive programme for Robertson school children--baseline data.

This study describes the baseline caries experience of a cohort school children in the Robertson area who were selected to take part in a longterm school-based preventive programme. On the whole baseline DMFT values for the various age groups did not differ significantly except for the 13-year-olds at Vergesig who had significantly higher values than those obtained at the other two schools. The D-component predominated with a moderate M-component and no filled teeth. The teeth at risk for the respective age groups did not differ significantly between the schools. The frequency of caries experience decreased from the molars to the central incisors except for the canines which were least vulnerable. The DMFT values were high and warrant the search for the most suitable preventive measures to facilitate reduction towards the WHO goal of 3 for 12-year-olds by the year 2000.
