White children had higher caries rates in permanent teeth than black children The difference in caries prevalence between black and white children was reduced in cities with a better socioeconomic status profile Caucasian children also had a better profile of cared-for teeth, with lower numbers of missing and untreated decayed teeth, higher rates of attendance, lower averages of teeth with preventive and restorative treatment needs, and higher proportions of children without dental treatment |
