BACKGROUND Evidence from studies involving small samples of children in Africa, India and South America suggests a higher dental caries rate in malnourished children. A comparison was done to evaluate wasting and stunting and their association with dental caries in four samples of South African children. DESIGN Cross-sectional study based on random(More)
In a case control study, 109 children with nursing caries (> or = 2 decayed, missing, or filled labial or palatal surfaces of primary incisor teeth) were matched for age, race, gender, and social class to 109 children without nursing caries from the same study areas. Mean dmfs and dmft scores were statistically higher in the nursing caries group but no(More)
The dentitions of 499 white preschoolchildren aged 1-5 years from a low fluoride area were examined with mirror and probe. The dmft values ranged from 1.0 +/- 2.0 at 1 year of age to 5.1 +/- 4.5 at 5 years of age while the overall mean for the group was 3.7 +/- 4.1. ""Rampant" caries prevalence varied according to the definition used. It is suggested that(More)
The aim of this study was to determine the degree of fluorosis in the primary dentition and the accompanying caries patterns in groups of preschool-children in high and low fluoride areas. Among 331 coloured children, aged 1-5 years, living in an area with water F concentrations ranging from 2.2 to 4.1 parts/10(6), 82% were caries free and the dmft values(More)
Dental caries, debris (DI-S) and sugar intake were determined for 766 rural Black, urban Black, coloured, Indian and White children, using standardized techniques. In general sucrose intake, both quantity and frequency was low in rural Black children yet these children had relatively few caries-free individuals and higher than expected mean dmft scores.(More)
