Higher fluoride levels in public drinking water during pregnancy may be linked to differences in children's cognition scores, NIH-funded study finds

A new NIH-funded study found associations between higher fluoride levels in public drinking water during pregnancy and lower child cognition scores, particularly in fluid reasoning. The study, which included 2,514 children, suggests that higher fluoride levels may impact cognitive development.

By looking at individual atoms in tooth enamel, UW and PNNL researchers are learning what happens to our teeth as we age

Researchers at UW and PNNL studied atomic composition of enamel samples from two human teeth, one 22-year-old and one 56-year-old, to understand how enamel changes with age. The study found higher levels of fluoride in the older tooth's shell regions, which could have implications for understanding tooth health as we age.

Journal of Dental Research publishes study exploring the impact of early childhood exposure to fluoride on cognitive neurodevelopment

A recent study published in Journal of Dental Research examined the relationship between early childhood fluoride exposure and cognitive development. The research found that there were no significant effects of fluoride exposure on cognitive neurodevelopment, with the hypothesis of non-inferiority tests also supporting this conclusion.

Water fluoridation less effective now than in past

A recent Cochrane review has found that the dental health benefits of adding fluoride to drinking water may be smaller now than before fluoride toothpaste was widely available. The review analyzed data from over 2,900 children in the UK and Australia, estimating a slight reduction in tooth decay, but with significant uncertainty.

Study explores association between fluoride exposure in pregnancy and neurobehavioral issues in young children

A new study led by University of Florida researcher Ashley Malin found a possible link between fluoride exposure during pregnancy and increased odds of neurobehavioral problems in children at age 3. The findings, based on an analysis of 229 mother-child pairs, suggest that higher fluoride levels may negatively affect fetal brain develo...

Water flouridation: Effective prevention for tooth decay and a win for the environment - Trinity research

A new study by Trinity College Dublin researchers shows that water fluoridation has the lowest environmental impact among community-level caries prevention programmes, offering a sustainable solution to prevent dental decay. The study also highlights its cost-effectiveness and ability to reduce disability-adjusted life years.

Journal of Dental Research study: Fluoridation is not associated with increase in osteosarcoma

A study published in the Journal of Dental Research found no association between community water fluoridation and an increased risk of osteosarcoma. The research, which analyzed data from over 500 patients, suggests that living in a fluoridated area is not a risk factor for osteosarcoma.

Water fluoridation confirmed to prevent dental decay in US children and adolescents

A recent study confirms the effectiveness of water fluoridation in preventing dental caries among US children and adolescents. The analysis found that counties with over 75% access to fluoridated drinking water experienced a 30-40% reduction in dental caries, particularly in primary teeth.

Water fluoridation in New South Wales

Researchers found that community awareness of poor oral health, framing fluoridation as a public health issue, and unified support from health professionals significantly influenced councillor decisions. The study's preliminary findings suggest that these strategies can be effective in promoting water fluoridation in other rural areas.
