Abstract
Rao and Thakur have shown that the antioxidants melatonin and alma (Emblica officinales, Indian gooseberry) are effective, both individually and in combination, against fluoride-induced genotoxicity in human peripheral blood lymphocyte cells, which was first described in humans in 1994. Some animal and
human work also suggests that fluoride (F) can impair the defensive response to genotoxicity by being deposited in high concentrations in the pineal gland and, through an enzyme-inhibiting action, reducing the secretion of melatonin, a powerful antioxidant able to eliminate free radicals and protect DNA. In having the capacity to be both genotoxic and impair melatonin secretion, F is similar to electromagnetic
radiation, at power line frequencies and above, and both have very low or zero thresholds for causing toxicity. In view of the seriousness of neoplasia, the effect of fluoride on melatonin secretion warrants further research.

Effect of pineal proteins at different dose level on fluoride-induced changes in plasma biochemicals and blood antioxidants enzymes in rats
Pineal glands secrets melatonin and various proteins and peptides which has many physiological functions. In keeping with this view, present experiment was conducted to know the effect of buffalo (Bubalus bubalis) pineal proteins (PP) at different dose level on fluoride-induced changes in plasma biochemicals and blood antioxidants enzymes in female

Fluoride-induced oxidative stress in rat's brain and its amelioration by buffalo (Bubalus bubalis) pineal proteins and melatonin.
Fluoride (F) becomes toxic at higher doses and induces some adverse effects on various organs, including brain. The mechanisms underlying the neurotoxicity caused by excess fluoride still remain unknown. The aims of this study were to examine F-induced oxidative stress (OS) and role of melatonin (MEL) and buffalo pineal proteins

Melatonin ameliorates fluoride induced neurotoxicity in young rats: an in vivo evidence
Objective: Developing brain is highly vulnerable to environmental toxins. Recently, fluoride was declared as a developmental neurotoxin and heralded search for natural neuroprotectant. In the present study, we have evaluated the neuroprotective and anti-inflammatory efficacy of melatonin in fluoride induced neurotoxicity. Methods: Animals were divided into following groups; the first group

Pre and post natal exposure of fluoride induced oxidative macromolecular alterations in developing central nervous system of rat and amelioration by antioxidants.
The effect of fluoride exposure during gestation and post gestation periods were studied to check the status of oxidant, antioxidant and macromolecular changes in CNS and ameliorative role of antioxidants. The pregnant Wistar albino rats were exposed to 50 and 150 ppm fluoride in drinking water and the pups born

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,

Luke (1997): The Effect of Fluoride on the Physiology of the Pineal Gland (Excerpts)
"The results suggest that fluoride is associated with low circulating levels of melatonin and this leads to an accelerated sexual maturation in female gerbils. The results strengthen the hypothesis that the pineal has a role in pubertal development."
