The distribution of enamel developmental defects in 759 11-12-yr-old children from South Wales is described. Overall, 8% of maxillary teeth were affected compared to 3.6% of mandibular teeth. Most teeth were affected equally on right and left sides of the mouth except for maxillary lateral incisors, which had significantly more defects on the right (P less(More)
In 1984 the prevalence and distribution of developmental defects of dental enamel in 791 children aged 15-16 years was determined using the DDE index. The children were all residents of the county of South Glamorgan, Wales, which has a public water supply containing less than 0.1 mg fluoride/litre. The teeth were dried but not cleaned prior to examination(More)
The prevalence of enamel developmental defects was assessed in 579 children aged 11 and 12 yr using the DDE Index. The teeth were dried prior to the examination and a normal dental operating light was used for illumination. Teeth with some type of defective enamel were seen in 48.9% of children. White/single opacities were present in 26.4% of children and(More)
An analysis of factors influencing the caries experience of adolescents in South Wales is presented. Approximately 1000 children were assessed for caries status and oral cleanliness in 1980 when aged 11-12 years and again in 1984 when aged 15-16 years. In addition, on both occasions, the children completed detailed questionnaires on dental health-related(More)

Orographic enhancement of wet deposition arising from thèseeder-feeder' e€ect is, by necessity, highly parametrised in long-range transport models of acid deposition that are long-term (i.e. annual average) and spatially resolved at tens of kilometres. Here, we describe a mechanistic approach to the incorporation of these mechanisms into such a model. The(More)
