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.
Cessation of public water fluoridation would lead to higher rates of tooth decay and increased healthcare costs in the US. The model suggests that current safe levels of fluoride have substantial ongoing benefits.
A new study reveals that targeted preventative measures can significantly reduce the economic burden of tooth decay, particularly in deprived groups. The research estimates that implementing upstream and downstream interventions could save £14,000 per person in the most deprived group.
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.
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.
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.

Researchers found that a refutational approach can help overcome misinformation, leading to fewer misconceptions and improved emotional responses. The study tested students' knowledge of fluoridation and found that those who read an article with a refutation had more positive emotions toward the subject.
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...
Researchers from Xi'an Jiaotong-Liverpool University developed a system to assess water quality challenges in Suzhou, China. The study found that the city's water capacity has increased since 2001 due to effective water management measures.
A study of 74 children in rural Ethiopian villages found that higher exposure to fluoride was linked to more errors on drawing and memory tests. The results suggest a potential association between high fluoride levels and cognitive impairment, particularly during early brain development and childhood.
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.
A new filtering technology inspired by biology can separate fluoride from chloride ions with twice the selectivity, potentially preventing waterborne diseases like fluorosis. The technology also has potential applications in industrial processes such as chemical production and mining.
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.
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.
A recent study published in Journal of Water and Health suggests that supplemental water fluoridation may be a contributing factor to rising type 2 diabetes rates in the United States. The study used mathematical models to analyze publicly available data on fluoride water levels and diabetes incidence rates across 22 states.
The symposium explores the efficacy and cost-effectiveness of community water fluoridation, as well as assessments of fluoride ingestion risks. It aims to address knowledge gaps on fluorides and their impact on oral health.
The study found that water fluoridation continues to be a cost-effective preventive measure, with annual per person savings ranging from AUS$56 in the 1970s to AUS$18 in the 1990s. However, the cost-saving benefits may decline with age due to plateaued new tooth decay and higher periodontal treatment needs.
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.
Community-based oral health research studies in Hawaii prioritize tangible oral health problems, including intervention trials. Community involvement is essential in addressing disparities in oral health among population subgroups.
A study of 1,189 Indian seventh-grade children found that nearly 13% had fluorosis, a primarily aesthetic condition affecting adult teeth during development. Children who started using fluoride toothpaste under age 2 showed more severe cases of fluorosis.
