Abstract
Fluoride generated the attention of toxicologists due to its deleterious effects at high concentrations in human populations suffering from fluorosis and with in vivo experimental models. Interest in its undesirable effects has resurfaced due to the awarenessFluoride generated the attention of toxicologists due to its deleterious effects at high concentrations in human populations suffering from fluorosis and with in vivo experimental models.

Pharmacological and toxicological effects of co-exposure of human gingival fibroblasts to silver nanoparticles and sodium fluoride
BACKGROUND: Silver nanoparticles (AgNPs) and fluoride (F) are pharmacological agents widely used in oral medicine and dental practice due to their anti-microbial/anti-cavity properties. However, risks associated with the co-exposure of local cells and tissues to these xenobiotics are not clear. Therefore, we have evaluated the effects of AgNPs and F

Arsenic and fluoride induce apoptosis, inflammation and oxidative stress in cultured human umbilical vein endothelial cells
Excessive amount of inorganic arsenic (iAs) and fluoride (F) coexist in drinking water in many regions, which is associated with high risk of vascular diseases. However, the underlying mechanisms are not well studied. The present study was to evaluate the effects of iAs and F individual or combined exposure on endothelial activation

Oxidative indices correlate with dyslipidemia and pro-inflammatory cytokine levels in fluoride-exposed rats
The aim of this study was to establish the effects of fluoride on lipid metabolism and attendant inflammatory response by exposing rats to 50 mg L-1 and 100 mg L-1 of fluoride through drinking water for seven weeks. Both concentrations led to hypercholesterolemia while the 100 mg L-1 concentration induced

Fluoride Impairs Ovary Development by Affecting Oogenesis and Inducing Oxidative Stress and Apoptosis in Female Zebrafish (Danio Rerio).
Highlights Fluoride exposure decreased FSH, LH and VTG levels in ovary of zebrafish. Fluoride exposure altered the transcriptional profiles of oogenesis-related genes. Fluoride exposure increased ROS production in ovary of zebrafish. Fluoride exposure induces oxidative stress in ovary of zebrafish. Fluoride exposure induces apoptosis through both extrinsic and intrinsic

The effects and underlying mechanism of excessive iodide on excessive fluoride-induced thyroid cytotoxicity
In many regions, excessive fluoride and excessive iodide coexist in groundwater, which may lead to biphasic hazards to human thyroid. To explore fluoride-induced thyroid cytotoxicity and the mechanism underlying the effects of excessive iodide on fluoride-induced cytotoxicity, a thyroid cell line (Nthy-ori 3-1) was exposed to excessive fluoride and/or excessive

Is the Ingestion of Fluoride an Immunosuppressive Practice?
This paper records several observations which suggest that habitual ingestion of small doses of fluoride, even as small as the 1 mg/L contained in fluoridated water, may decrease the function of the immune system.

Does Fluoride Ingestion Affect Developing Immune System Cells?
Considerations, supported by some published experimental evidence, suggest that fluoride released during the resorption of high-fluoride bone may produce detrimental effects not only on bone cells but on developing cells of the immune system.

Fluoride & Oxidative Stress
A vast body of research demonstrates that fluoride exposure increases oxidative stress. Based on this research, it is believed that fluoride-induced oxidative stress is a key mechanism underlying the various toxic effects associated with fluoride exposure. It is also well established that fluoride's toxic effects can be ameliorated by exposure

Nutrient Deficiencies Enhance Fluoride Toxicity
It has been known since the 1930s that poor nutrition enhances the toxicity of fluoride. As discussed below, nutrient deficiencies have been specifically linked to increased susceptibility to fluoride-induced tooth damage (dental fluorosis), bone damage (osteomalacia), neurotoxicity (reduced intelligence), and mutagenicity. The nutrients of primary importance appear to be calcium,
