Item Social class, parents' education and dental caries in 3- to 5-year-old children(1990) Chosack, A.; Cleaton-Jones, P.; Matejka, J.; et alThe caries prevalence of 1273-, 4- and 5-y-old white children was determined with mirror and probe under natural light at mother and child clinics. The social class of the family, the educational level of the mother and that of the father were determined from a questionnaire filled in by the accompanying adult at the time of examination. Both social class and parent's education had a statistically significant influence on the caries prevalence: those in the lower social classes and with parents without tertiary education had a much higher prevalence of cariesItem Permanent denition caries in KwaZulu and Namibia 11-year-olds(1990) Hargreaves, J. A.; Cleaton-Jones, P.; Matejka, J.; et alThe permanent dentitions of 11-year-old children in Namibia (n = 295) and KwaZulu (n = 308) living in rural and urban areas were examined using WHO caries diagnostic criteria. In low fluoride areas (less than 0.15 ppmF) significantly more caries was present in rural compared to urban KwaZulu but the prevalences in rural and urban Namibia were similar although significantly higher than in an area with 1.56ppmF in the drinking water. There was significantly more caries in rural Namibia than KwaZulu but the urban prevalences in both regions were similar. It is suggested that the urban findings are useful predictors for the needs of 11-year-old black children but local baseline surveys should be undertaken before considering dental programmes, treatment or preventive, for different rural communities in South Africa.Item Comparison of three anaesthetic scavenging devices using cuffed and non-cuffed nasal endotracheal tubes during dental anaesthesia(1981) Moyes, D.; Cleaton-Jones, P.; Shaw, R.; et alItem Induced exchange of fluids in the treatment of post-traumatic infective lesions(1968) Retief, D. J.; Dreyer, C. J.; Retief, D. H.; et alItem An evaluation of an in vivo enamel acid etch biopsy technique for fluoride determination(1974) van der Merwe, E H M; Retief, D H; Barbakow, F H; et alItem The quantitative analysis of Cr, Ba, Sb, Ag, Zn, Co and Fe in normal human enamel and dentine by neutron activation and high resolution gamma-spectrometry(1970) Retief, D. H.; Cleaton-Jones, P. E.; Turkstra, J.; et alItem An analysis of fractures of the facial skeleton in three populations in the Johannesburg urban area(1985) Beaumont, E.; Lownie, J. F.; Cleaton-Jones, P. E.; et alItem An in vivo evaluation of an lontophoretic Technique for increasing the surface fluoride content in enamel(1973) Barbakow, F. H.; van der Merwe, E. H. M.; Scanes, S. G.; et alSurface enamel fluoride concentrations were determined in IS subjects before and after topical fluoride applications. These IS subjects were divided into 2 groups, one of which received the fluoride applications iontophoreti- cally whereas the control group had the identical fluoride applications without the use of the current. The results indicate that the greatest increase in fluoride concentrations resulted after 3 applications done at weekly intervals when the iontoplioretic technique was employed. Two iontophoretic fluoride applications with an interval of a week between them resulted in a less marked increase whereas no increase was observed when fluoride was applied once only. The increase in the fluoride concentration of the surface enamel was not as significant when the fluoride was applied without the use of current.Item The quantitative analysis of Sr, Au, Mn and Na in normal human enamel and high resolution gamma spectrometry(1971) Retief, D H; Cleaton-Jones, P E; Turkstra, J; et alItem The mineral composition of enamel from two South African population groups(1979) Retief, D. H.; Turkstra, J.; Cleaton-Jones, P. E.; et al
