Overuse of Fluoride in Public Water Systems: Stimulating Fluorosis Rather Than Preventing Dental Caries [PDF]

open access: yes, 2013
In the early 1940’s, researchers sponsored by the Centers for Disease Control and Prevention (CDC) discovered an inverse correlation between the prevalence of dental caries and the quantity of fluoride consumption and exposure.

Disrupted Iron Storage in Dental Fluorosis [PDF]

open access: yesJournal of Dental Research, 2019
Enamel formation and quality are dependent on environmental conditions, including exposure to fluoride, which is a widespread natural element. Fluoride is routinely used to prevent caries. However, when absorbed in excess, fluoride may also lead to altered enamel structural properties associated with enamel gene expression modulations. As iron plays a

Adsorption and Sensing Behavior of Pristine, P‐Doped, and Al‐Doped Boron Nitride Nanosheets Toward Toxic Hydrogen Fluoride Gas: Insights from Density Functional Theory Analysis

open access: yesChemistryOpen, Volume 15, Issue 5, May 2026.
This study reveals how pristine, P‐doped, and Al‐doped boron nitride nanosheets interact with toxic hydrogen fluoride (HF) gas using density functional theory (DFT) simulation. Enhanced adsorption and charge transfer in doped systems highlight their potential as sensitive and selective gas sensors, providing molecular‐level insights for nanoscale ...

Dental fluorosis caused by volcanic degassing in West Ambrym, Vanuatu : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Earth Science at Massey University, Palmerston North, New Zealand [PDF]

open access: yes, 2006
Fluorosis, both dental and skeletal, is a disease afflicting millions of people worldwide and is caused primarily by the ingestion of fluoride-rich drinking water. Usually, this is groundwater that has leached fluoride from underlying rock deposits.

Pycnodysostosis With Papilledema and Isolated Low Parathyroid Hormone Levels in an Eight‐Year‐Old Girl: A Genetically Confirmed Case Report

open access: yesClinical Case Reports, Volume 14, Issue 4, April 2026.
ABSTRACT Pycnodysostosis is a rare autosomal recessive skeletal dysplasia resulting from pathogenic variants in the CTSK gene, which encodes cathepsin K, a lysosomal cysteine protease expressed in osteoclasts. Deficiency of this enzyme leads to defective bone resorption and generalized osteosclerosis.
