本研究的目的是分析囊性纤维化儿童和非囊性纤维化儿童的牙齿中钙和磷的百分比与不同的变量，即性别、年龄、牙齿类型、供水面积、孕期和母亲吸烟和饮酒习惯。分析方法是对牙冠样品进行质子诱发X射线发射和质子诱发伽马发射。T检验结果显示，对于切牙和总牙数，CF+NT(囊性纤维化+非四环素类抗生素)组的牙齿中钙含量低于NCF(非囊性纤维化)组。在NCF中，门牙比非门牙具有更高的钙含量。城市CF+NT的牙齿钙含量低于城市NCF的牙齿。这一点适用于整个地区的人口。氟化区NCF人群牙齿中的钙、磷含量均高于非氟化区人群。在母亲吸烟的CF+NT儿童的牙齿中，CA被耗尽，而在母亲饮酒的NCF儿童的牙齿中，P被消耗。报告了单个牙齿的高和低钙、磷的值。
The objective of this study is to analyze the percentage of Ca and P in teeth from children with and without cystic fibrosis with respect to different variables, namely, gender, age, type of teeth, area fluoridation of water supply, term of pregnancy, and maternal smoking and drinking habits. The method of analysis is proton-induced X-ray emission and proton-induced gamma emission on tooth-crown samples. T-test results show less Ca in the teeth of the population of CF + NT (cystic fibrosis + nontetracycline antibiotics) than in that of NCF (noncystic fibrosis) for incisors and the total tooth population. It also shows greater Ca for incisors than for nonincisors for NCF. Teeth from urban CF + NT have less Ca than those from urban NCF. This holds for the total area population. Both Ca and P in teeth of NCF population living in fluoridated areas are greater than in those living in nonfluoridated area. Ca is depleted in the teeth of CF + NT children whose mothers smoke and P is depleted in the teeth of NCF children whose mothers drink. High and low Ca and P values for individual teeth are reported.
