The present study compared the mineral contents of enamel and dentin of primary teeth from children exposed to desalinated water with those from children drinking ground water. The study comprised of two groups of teeth, seven primary teeth from children living in areas supplied exclusively with desalinated water and seven primary teeth from children that have been exposed solely to ground water from in-utero until the teeth were either extracted or naturally shed. Mineral content of three tooth regions was determined by scanning electron microscopy with an energy dispersive X-ray spectrometer (EDS). The main ion content of each region was calculated. Children exposed to ground water presented higher levels of magnesium in pre- and post- natal enamel than children living in areas supplied exclusively with desalinated water but without significant differences. The same was found for calcium levels. Excluding post-natal enamel calcium level (of borderline statistical significance), no significant differences were found in magnesium and calcium levels of primary teeth enamel and dentin of children exposed to desalinated water in comparison to children exposed to ground water. Mineral content of enamel and dentin in primary teeth is not affected by consuming desalinated water.
本研究比较了饮用淡化水的儿童与饮用地下水的儿童乳牙牙釉质和牙本质中的矿物质含量。该研究包括两组牙齿，一组是来自仅供应淡化水地区儿童的七颗乳牙，另一组是从子宫内就一直只接触地下水直到牙齿被拔除或自然脱落的儿童的七颗乳牙。通过带有能量色散X射线光谱仪（EDS）的扫描电子显微镜测定三个牙齿区域的矿物质含量。计算每个区域的主要离子含量。饮用地下水的儿童在出生前和出生后的牙釉质中镁含量高于仅供应淡化水地区的儿童，但差异不显著。钙含量也有同样的情况。除了出生后牙釉质钙含量（具有临界统计学意义）外，饮用淡化水的儿童与饮用地下水的儿童乳牙牙釉质和牙本质中的镁和钙含量没有显著差异。乳牙牙釉质和牙本质中的矿物质含量不受饮用淡化水的影响。
