从生活在印度北部农村地区的272名儿童中每人收集约8 ml唾液，平均分布在4-7岁和12-16岁年龄组中，并分层为低、中、高龋齿组。用原子吸收分光光度法分析唾液中的锌、铜、铁、锰，用氟敏电极分析唾液中的氟。元素铜和氟有一个一致的，负相关的龋齿经验。唾液中锌、铁、锰含量与患龋经历无一致性关系。
About 8 ml of saliva were collected from each of 272 children, living in rural areas in North India, equally distributed into age groups 4-7 and 12-16 yr and stratified into low, moderate and high caries groups. The salivas were analysed for Zn, Cu, Fe, Mn by atomic absorption spectrophotometry and for F with a fluoride-sensitive electrode. The elements Cu and F had a consistent, inverse relationship with caries experience. The concentration of Zn, Fe and Mn in saliva did not have any consistent relationship with caries experience.
