What Are The Appropriate Guidelines For Fluoride Intake?

The proper use of fluoride has changed oral health in the past 70 years, in part because of the guidelines for fluoride intake. Recently, researchers are questioning these long-term guidelines as advice for decades. This issue of the Journal of Dental Research is an electronic supplement to the Journal of Dental Research. It presents the proceedings of the Symposium of the IADR 95th Plenary Session in San Francisco, USA, which includes the current guideline on fluoride intake.

Since the benefits of fluoride in drinking water were recognized for the first time, fluoride was ingested and considered the basis for automatic labor. However, the source of fluoride intake has changed, and the prevalence and severity of dental caries and dental fluorosis have changed, leading to the time being to revisit the intake of fluoride. Optimal fluoride intake should balance the prevention of dental caries and the reduction of dental fluorosis.

“When fluoride is the only important source of fluoride, it first proposes guidelines for fluoride intake. Now that there are many ways to deliver fluoride, it’s time to consider these guidelines, considering the current balance of benefits and risks. Understanding,” Guest Editor Andrew Rugg-Gunn, Newcastle University and Borrow Foundation, UK said.

“Experts from around the world have given assurance that the optimal fluoride intake range is currently reasonable and there is sufficient evidence to increase the upper limit of fluoride intake. Fluoride is used to prevent dental caries from increasing as adults use it. Adult fluoride intake should have different guiding significance than infants and young children. ”

“Although the current changes to the guidelines on adequate intake and fluoride caps have not been resolved, it is agreed that there is reason to reconsider the current guidelines,” said IADR chairman Angus William G. Wools, Edinburgh University, who also contributes to this issue.

“Need further research and international discussions to answer the questions raised by the seminar.”

Importantly, the seminar gave priority to the following research gaps:

Given the benefits of reducing dental caries, what is the acceptable level of fluorosis in the global population?
What is the best way to measure total fluoride intake and exposure?
What is the best way to estimate the total fluoride intake of children up to 3 to 4 years of age who are exposed to fluorinated or non-fluorinated water or fluoride salts?
What is the best way to evaluate the liquid intake pattern of children in different areas under different outdoor air temperatures?
Do we need to regularly analyze fluoride concentrations in infant formula, bottled water and baby food?
Do we need to verify biomarkers exposed to fluoride?
What are the effects of different types of exercise on the metabolism of fluoride?
What is the relationship between genetic polymorphisms and glaze fluorosis?
What is the relationship between malnutrition and enamel fluorosis?
Does calcium supplementation help reduce enamel fluorosis?
How does fluoride affect dental caries development?
What is the effect of the preparation of low-fluoride toothpaste modified to increase the efficacy of anti-dental caries?
