- The fluoride content in surface enamel and its relationship to caries experience was studied in a group of Icelandic schoolchildren living in a low-fluoride area. Fluoride content was assessed by means of in vivo enamel biopsies sampled from 248 subjects aged 11 and 12 years. Dental examinations were performed in conjunction with the biopsy sampling and by the same examiner 1 year later. The prevalence and incidence of initial (DSI) and manifest (DFS) caries lesions were recorded separately. A median fluoride concentration of 610 ppm at a median biopsy depth of 4.2 microns was observed. A significant positive correlation was found between DSI and enamel fluoride content in girls and all older children. Additionally, surface enamel fluoride was measured in 72 Swedish children from a low-fluoride area but exposed to regular topical fluoride treatments. The difference in mean fluoride concentrations between the Icelandic and Swedish study populations was highly significant. From the measured fluoride concentrations the enamel fluoride profiles for both study populations were constructed. The differences in fluoride content were most pronounced in the outermost layer, apparently reflecting the higher exposure to and acquisition of topical fluoride in the Swedish children.

Journal article (peer-reviewed)abstract
- Dietary habits with regard to sugar consumption and caries experience were studied in a group of 275 Icelandic children aged 12 and 13 years. The pattern of meals and sugar-containing food intake frequency were assessed by means of a dietary questionnaire. All dental examinations were performed by one examiner, using standardized methods and diagnostic criteria. Only 75% of the children had three regular meals daily. Breakfast and lunch were the most frequently omitted meals. Sweet buns were consumed by 32% of the children with meals and by 58% between meals, whereas soft drinks were consumed by 42% and 46%, respectively. Eighty-three per cent of the children reported eating sweets daily. The most popular products included confectionery, buns, cakes, and soft drinks, which constituted 53% of the intake with meals and 68% of that between meals. A higher caries incidence was associated with frequent intake of buns and cakes with meals and confectionery.
