“…The mean dietary fluoride intake was 0.28 mg/day (0.019 mg/kg body weight/day), which was lower than a previous Japanese estimate (0.95-1.03 mg/day) based on food consumption tables [Soejima, 1994]. Advantages of the method of the current study are that analyzed samples excluded food items not actually consumed and that the consumed materials could be analyzed accurately [Chowdhury et al, 1990]. The recovery of fluoride in the assay system was complete when tested by adding sodium fluoride to the food samples.…”

This study was conducted to determine the fluoride intakes in 94 preschool children aged 3, 4 and 5 (n = 30, 30, 34, respectively) residing in Yokkaichi, Mie Prefecture (< 0.16 ppm F water supply). The parents duplicated all the diets that their children ingested on 3 separate days during a 1-year period. The acid-diffusible fluoride in the diet was isolated by the acid-diffusion technique and measured with a fluoride electrode. The mean daily fluoride intakes from diet alone by children aged 3, 4 and 5 were 0.30 mg (n = 29, SD 0.19), 0.28 mg (n = 30, SD 0.19) and 0.30 mg (n = 34, SD 0.19), respectively. The total estimated mean values from diet and dentifrice were 0.35 mg (n = 29, SD 0.22, range 0.13–1.00), 0.33 mg (n = 30, SD 0.19, range 0.13–0.86) and 0.39 mg (n = 34, SD 0.18, range 0.18–1.01), respectively. It was concluded that the mean (±SD) total fluoride from diet and dentifrice in 3- to 5-year-old Japanese children was 0.35 ± 0.19 mg/day (0.021 ± 0.012 mg/kg body weight).

“…In planning fluoride applications for oral health, the daily fluoride intakes (DFIs) 2) from drinking water and food stuffs must be evaluated as basic data for human body as an index of routine fluoride intake. In Western countries, DFIs from foods and drinking water are evaluated for many years and monitored regularly in terms of fluoride exposure, especially in considering the occurrence of dental fluorosis 5,9,15,16,[19][20][21][22][23][24]29,30,34,35,45) . The fluoride intake of the Japanese population has been investigated by several groups since the 1950's, but the studies have been focused primarily on adults 13,32,33,36,43,44) .…”

The mean daily fluoride intake in infants was estimated on the basis of their intake of commercial foods for infants in Japan and evaluated in order to establish the effectiveness and safety criteria for water fluoridation, which is practiced as a preventive measure for dental caries suitable in life stages from children to the elderly. Based upon the intakes of foods for infants, the mean daily fluoride intake was estimated to be 0.166 mg in infants aged 3-4 months, 0.202 mg in those aged 5-6 months, and 0.266 mg in those aged 7-8 months. The mean daily fluoride intake per kg of body weight at these ages was in the range of 0.023-0.029 mg/kg, which was about half of the standard daily fluoride intake for infants and children advocated by Ophaug et al., as 0.05-0.07 mg/kg.From our results, the daily fluoride intake of infants from foods in Japan is estimated to be equivalent to or lower than the values of previous reports in non-fluoridated areas. Consequently, our data support the argument that water fluoridation and the appropriate use of fluoride for dental caries prevention in Japan are needed on the basis of scientific criteria in terms of fluoride exposure related to food intake during tooth formation.
