Special Issue Information

Dear Colleagues,

Fluoride is widely used in dental products and water fluoridation to prevent tooth decay. However, growing concerns have emerged regarding the potential health risks of excessive fluoride exposure. This research line addresses these concerns and provides scientifically sound information to inform public health decision making.

This research line aims to:

  • Identify sources of fluoride exposure: This includes assessing both natural and anthropogenic sources, such as drinking water, different drinks and foods, toothpaste, and industrial emissions.
  • Evaluate the health effects of fluoride exposure: This involves examining the potential adverse effects of fluoride on various organ systems, including teeth, bones, and the nervous system.
  • Develop risk assessment models: These models will predict the likelihood of individuals or populations developing fluoride-related health problems.
  • Inform public health policies: The research findings will guide the development of evidence-based public health policies to minimize fluoride exposure and protect public health.

This Special Issue aims to comprehensively understand the complex relationship between fluoride exposure and human health. The findings from this research will be essential for protecting public health and ensuring the safe intake and exposure of fluoride in all ambits.

Coffee is part of our daily lives since it is a drink with a symbolic value, both in our social relationships and as a stimulating drink. The main objective of this paper is to conduct a risk characterization of fluoride overexposure from the consumption of these beverages; for this purpose, in the present study, the fluoride concentration was determined in 80 samples of different brands of coffee commonly consumed in the Canary Islands, and the risk derived from their intake was then evaluated. Significant differences (p < 0.05) were found between the coffee brands soluble Nescafé Classic®, Saimaza®, Auchan®, Tirma® soft blend, and Hacendado® and the other analyzed brands. The brand that recorded the highest mean fluoride levels is “Hacendado descafeinado®” (0.308 mg/L). The problem with coffee is not the fluoride it contains but the fact that, according to the survey results, most coffee drinkers brew their coffee with tap water (over 51% of respondents use tap water). The results of the fluoride content in coffee prepared with tap water from the different areas of Tenerife in the Canary Islands (metropolitan, northern, and southern areas) have reported higher concentrations of fluoride: north (max. concentration found of 16.68 mg/L), south (max. concentration found of 8.47 mg/L) and metropolitan (max. concentration found of 4.73 mg/L). Coffee has not been identified as a risk of dietary overexposure to fluoride; however, the use of tap water for its brewing has been identified as a factor that considerably increases its concentration. Therefore, the use of bottled water is recommended, especially in regions such as the Canary Islands, which have high concentrations of fluoride in their water. Full article
