This study was designed to determine fluoride, sucrose and glucose intakes of 94 preschool children aged 3, 4 and 5 years at the starting point (30, 30, 34 respectively) residing in non-fluoridated areas (<0.16 Fppm) in Mie prefecture. The parents quantitatively and qualitatively duplicated all the diets that their children ingested on three separate days over a period of one year (Chowdhury et al., 1990). The diet samples were homogenized with known volumes of distilled water at the speed of 19,000 r.p.m. for ten minutes. The acid-diffusible fluoride in the liquid homogenate was isolated by the hexamethyldisiloxane-hydrochloric acid diffusion technique (Taves, 1968), and measured with a fluoride electrode. Fluoride intake from the use and ingestion of dentifrices was also estimated for each child. The levels of sucrose and fructose were determined by using a sugar analyzer (Model 2700 YSI, USA). As the value of fluoride intake in one 3-year-old boy was extremely high, it was performed with Smirnov test for extreme values. The obtained value was significantly different from the normal distribution and it was excluded (p=0.01). The data of fluoride intakes were finally obtained from 93 children with 29 (14 boys : 15 girls) aged 3, 30 (15 : 15) aged 4, and 34 (19 : 15) aged 5. The mean daily fluoride intakes from foods and beverages alone by children aged 3, 4 and 5 were 0.296 ± 0.193 mg (0.020 ± 0.013 mg/kg body weight), 0.275 ± 0.186 mg (0.016 ± 0.011 mg/kg body weight) and 0.303 ± 0.187 mg (0.016 ± 0.011 mg/kg body weight), respectively. The percentages of those with dentifrices containing fluorides were 66.7, 70.0 and 85.3, and the mean daily fluoride dentifrice uses 0.392 ± 0.221 g, 0.360 ± 0.258 g and 0.464 ± 0.215 g, respectively. The mean daily sucrose and fructose intake were 12.0 ± 6.9 g and 10.9 ± 5.5g, respectively.

本研究测定了米县非氟地区94名3、4、5岁学龄前儿童(分别为30、30、34)的氟、蔗糖和葡萄糖摄入量。父母在数量和质量上复制了他们的孩子在一年的时间里在三天内摄入的所有饮食(Chowdhury等人，1990年)。用已知体积的蒸馏水以每分钟19,000转的速度将饮食样本均质。十分钟。用六甲基二硅氧烷-盐酸扩散技术(Taves，1968)分离液体匀浆中酸可扩散的氟化物，并用氟化物电极进行测定。还估计了每个儿童因使用和摄取牙膏而摄入的氟化物。用美国2700YSI型糖分析仪测定蔗糖和果糖水平。由于1名3岁男童的氟摄入量极高，故对其进行了斯米尔诺夫极值检验。所得结果与正态分布有显著差异，不含正态分布(p=0.01)。93名3岁、30名(15：15)、34名(19：15)3岁、4岁、5岁儿童的氟摄入量分别为0.296±0.193 mg(0.020±0.013 mg/kg体重)、0.275±0.186 mg(0.016±0.011 mg/kg体重)和0.303±0.187 mg(0.016±0.011 mg/kg体重)。使用含氟牙膏的比例分别为66.7%、70.%和85.3%，日均含氟牙膏用量分别为0.392±0.221、0.360±0.258和0.464±0.215 g。日均摄入蔗糖12.0±6.9g，果糖10.9±5.5g。
