Special Issue Information

Dear Colleagues,

Dietary fluoride intake is widespread. Most of the United States and a sizable minority of Canada receives fluoridated community drinking water for dental caries prevention. In Mexico, most salt is fluoridated. Internationally, China and India commonly encounter high drinking water fluoride levels that are either naturally occurring or due to pollution, respectively.

Dietary fluoride intake can occur via consumption of foods and beverages reconstituted with fluoridated water, or by consuming foods with added fluoridated salt. Additionally, dietary sources of fluoride can include green and black tea, foods sprayed with fluoride-containing pesticides, and certain seafoods, for example. While the topical dental benefits of fluoride are well-established, chronic consumption of fluoride, even at low exposures, has been associated with adverse health outcomes.

This Special Issue will include manuscripts that focus on dietary fluoride intake and factors that may influence fluoride metabolism. Furthermore, this issue will also include studies that examine pathophysiological factors that may modify associations of fluoride intake with health outcomes. The presented materials include studies conducted by scientists with expertise in fluoride exposure, dietary fluoride intake, metabolism, and/or associated health outcomes. The research presented herein may be of interest to epidemiologists, public health scientists, physicians, and policy makers. We welcome both reviews and original manuscripts.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

Abundant information exists on fluoride intake and excretion in populations exposed to fluoridated water, but not fluoridated salt, where fluoride is eaten through a combination of foods and beverages. This study assessed associations between dietary patterns, fluoride intake and excretion in Mexican women exposed to fluoridated salt. We estimated dietary fluoride intake and excretion (mg/day) from 31 women using 24-h recalls (ASA24) and 24-h urine collections (HDMS diffusion method) and assessed agreement among both estimates of exposure with a Bland-Altman plot. Dietary patterns among the sample were explored by Principal Component Analysis and associations between these patterns and both fluoride intake and excretion were estimated. using Quantile Regressions. Median dietary fluoride intake and excretion were 0.95 and 0.90 mg/day, respectively, with better agreement at values below 1.5 mg/day. We identified three dietary patterns: “Urban Convenience”, “Plant-based” and “Egg-based”. The “Urban Convenience” pattern, characterized by dairy and convenience foods was associated with an increase of 0.25 mg and 0.34 mg of F in the 25th and 50th percentiles of intake respectively, (p < 0.01), and a marginal 0.22 mg decrease in urinary fluoride (p = 0.06). In conclusion, in this sample of Mexican women, a dietary pattern rich in dairy and convenience foods, was associated with both fluoride intake and excretion. Full article
