the cost-effectiveness of a modified supervised toothbrushing program was compared to a conventional program. a total of 284 five-year-old children presenting at least one permanent molar with emerged/sound occlusal surface participated. in the control group, oral health education and dental plaque dying followed by toothbrushing with fluoride dentifrice was carried outfour times per year. with the test group, children also underwent professional cross-brushing on surfaces of first permanent molar rendered by a dental assistant five times per year. enamel/dentin caries were recorded on buccal, occlusal and lingual surfaces of permanent molars for a period of18 months. the incidence density (id) ratio was estimated using poisson's regression model. the id was 50% lower among boys in the test group (p = 0.016). the cost of the modified program was us$ 1.79 per capita. the marginal cost-effectiveness ratio among boys was us$ 6.30 per avoided carie. the modified supervised toothbrushing program was shown to be cost-effective in the case of boys.
