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.
