Dental caries in South African white children aged 1-5 years.

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 for epidemiologic studies rampant caries should be defined as a dmft value of 5 or more and that labial caries should be regarded as a specific entity.

Dental caries in rural and urban black preschoolchildren.

The dentitions of 439 rural and 192 urban black children aged 1-5 years were examined with mirror and probe. Dental caries was common and the percentage prevalence and dmft values were similar in children of 1-3 years in both groups. At 4 years of age there was a twofold increase in dental caries in the urban children to reach a dmft score significantly greater than that in the rural children (P less than 0.01). Labial caries was common in rural children but rare in urban children while rampant caries (dmft greater than or equal to 5) exhibited the opposite pattern.

Growth, school attendance, and serum albumin levels in South African black children of 10-12 years.

Studies on representative series of South African Black schoolchildren aged 10-12 years revealed the following. (1) In the age sex groups, mean proportions lying below the Boston 3rd percentile of weight for age were high (a very common phenomenon), ranging from 20-84 per cent. (2) Of total moieties above and below the 3rd percentile, 96 per cent and 95 per cent had normal weight for height (more than 80 per cent of the 50th percentile of reference standards). (3) Both moieties had equally excellent records of school attendance, 94 per cent and 93 per cent. (4) Mean serum albumin levels, also the proportions having relatively low levels, did not differ significantly, either in the respective subgroups above and below the 3rd percentile, or in groups of pupils accustomed and not accustomed to supplementary school-feeding. Accordingly, it is considered that classification, without qualification, of schoolchildren as malnourished simply because of slower growth compared with western norms is unwarranted.

A socio-economic, health and cultural survey in Soweto.

The socio-economic, health and nutritional status of 186 families in Diepkloof, Soweto, was studied. The results, detailed in the text, reveal considerable socio-economic ills, of which the most important is the observation that 30% of the families existed below the poverty datum line, even when there was more than one wage-earner. More emphasis on health education and the promotion by health personnel of a better understanding of the backgrounds of clinic and hospital patients are urgent priorities for health services.
