Mean DMFT scores of school groups of Black pupils (both sexes) ranged from 0.9 and 2.0 in rural areas, to 4.2–6.7 in urban areas (where data were far higher than such obtained 7 years ago), and were 9.2 and 10.2 for White pupils. Corresponding mean daily sugar intakes were - rural Blacks, 69 g and 97 g, urban Blacks 118–141 g, respectively (all slightly higher than previously); and Whites 102 g and 123 g. Mean DMFT scores of girls were higher than those of boys; yet while mean sugar intakes of Black girls and boys were somewhat similar, White girls' intakes were much lower than those of White boys. In the ethnic-sex groups studied, mean DMFT scores for pupils in upper, compared with lower, third of sugar intake, were higher in nine of the 14 sub-groups. Mean DMFT scores in upper, compared with lower, third of exposure to snack practices were higher in 11 of the 14 groups. However, most of the differences were slight. In further research, more intensive enquiries should be pursued on roles of ethnic and familial factors, as well as on roles of inter-acting dietary components additional to sugar and sugar-containing foods.Type of Medium: Electronic ResourceURL: -

Published 1982Staff ViewISSN: 1600-0528Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: MedicineNotes: Abstract Investigations on caries profile and state of teeth treatment were made on 3752 high school pupils of 16–18 years, namely, rural and urban Black, Indian, Colored (Eur-African-Malay) and White pupils. Rural Blacks had a low mean DMFT of about 2, and a caries-free prevalence of 52%. Of the few with affected teeth, 10% were extracted, none filled, and 90% decayed; i.e. restorative dental attention was virtually nil. Among English and Afrikaans pupils attending Government Schools, mean DMFT was about 10, and caries-free prevalence negligible. Of affected teeth, 13% were extracted, 59% filled and 28% decayed. The situations regarding the urban Black, Indian and Colored groups were intermediate. The Jewish pupils, well-circumstanced and attending private schools, had a mean DMFT of 6.5, moreover 6% were caries-free. Of affected teeth, 1% had been extracted; 93% were filled, and only 6% remained decayed. Since it transpired that the diets of the three White subgroups, cariogenically, were much the same, the advantageous position of the Jewish pupils was judged to be due primarily to their excellent oral hygiene motivation, particularly their demonstrably regular visits to dentists.Type of Medium: Electronic ResourceURL: -

ISSN: 1573-2568Source: Springer Online Journal Archives 1860-2000Topics: MedicineNotes: Abstract Colonic cancer is rare in primitive populations. In western populations it was uncommon in the past, but now accounts for about 3% of all deaths. The cause almost certainly lies with dietary changes. Probably, alterations in bowelmilieu interieur, from interaction between metabolites and microbacteria, promote carcinogenesis. Changes in intakes of protein, fat, sugar, refined cereal products, and crude fiber have been advanced as predisposing or causative factors. Evidence suggests that (i) fall in fiber intake, but (ii) rise in fat intake, in their ability to increase fecal concentrations of bile acids and sterols (possible precursors of carcinogens) are most likely to be culpable. As preventive measures, a significant rise in fiber intake is practicable only from regular bran ingestion. A major reduction in fat intake is grossly unlikely. Even were rigorous dietary changes implemented, an early fall in colonic cancer incidence is highly improbable due to the long-term character of the disease. Future research must include characterization of the diet, metabolism, and disease pattern of segments of western populations who have low colonic cancer mortality rates; also, elucidation of the bearing of various intakes of different food components on the biochemistry and microbiology of the feces.Type of Medium: Electronic ResourceURL:
