| Abstract: | A bstract — Summer and winter samples of first-morning urine from 168 pre-school children attending kindergartens in fluoridated and non-fluoridated communities in South Australia were analysed for fluoride and creatinine concentration. The urinary fluoride: creatinine ratio, as an index of fluoride ingestion, was greater in winter for both the fluoridated and non-fluoridated area samples, the difference being interpreted as a result of increased losses of fluoride through the sweat in summer. The results do not indicate a need to vary the concentration of fluoride in the reticulated water supply with the seasons. |
