INTRODUCTION
Fluorosis is an endemic disease that has affected 70 million individuals and is prevalent in 22 states of India, particularly in parched parts of the country.[1] The process of removal of harmful fluoride from water is called defluoridation.[2] The world's ground fluoride stores are estimated to be 85 million tons, of which almost 12 million tons are in India.[3] As Kaiwara, a part of Chikkaballapur district, Karnataka, has no alternate source of water, it is dependent solely on gr

Background: The Maternal-Infant Research on Environmental Chemicals (MIREC) Study was established to obtain Canadian biomonitoring data for pregnant women and their infants, and to examine potential adverse health effects of prenatal exposure to priority environmental chemicals on pregnancy and infant health.
Methods: Women were recruited during the first trimester from 10 sites across Canada and were followed through delivery. Questionnaires were administered during preg

Salt fluoridation in Jamaica
Salt fluoridation was introduced into Jamaica (population, 2.5 million) in 1987; all salt for human consumption is fluoridated (30). Fluoride toothpastes had been available in the country since 1972, and while their use may have had a protective effect (32), the notable decline in the prevalence of dental caries after 1984 may be considered to be primarily attributable to the introduction of fluoridated salt (27).
In 1984, a survey of oral health ca
