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.

Facts alone fall short in correcting science misinformation

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.

Excess fluoride linked to cognitive impairment in children

Fluoride consumption linked to diabetes using mathematical models

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.

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.

Water fluoridation still a cost-effective preventive measure

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.
