Fluoride exposure among pregnant women in California

Water fluoridation has been cited as one of the dental field’s most successful interventions to improve dental health. Since 1945, when the United States implemented community water fluoridation, rates of cavities have declined. Also, providing fluoridated tap water to most residents, regardless of income, education, or socioeconomic status, can reduce disparities in dental health. Fluoride … Continue reading Fluoride exposure among pregnant women in California

So many chemicals—how do we decide which ones to study?

The question is no longer whether environmental chemical exposures produce adverse health effects in children, but rather which chemicals have the most harmful impact. Fetuses and children are especially susceptible to environmental influences. Scientists and physicians are concerned that over the last 10-30 years, the prevalence of certain childhood diseases has increased, including adverse birth … Continue reading So many chemicals—how do we decide which ones to study?
