Abstract
Excessive consumption of fluoride through drinking water or other sources lead to skeletal and dental fluorosis. According to the world health organization 23 nations are facing the problem of fluorosis. In the recent past researchers describe the non-skeletal fluorosis where soft tissues and major organs are the victims of fluoride toxicity. Hence in the present study we attempted to investigate the structural changes in various brain areas followed by fluoride exposure and to explore the protective effect of ascorbic acid and Ginkgo biloba against fluoride neurotoxicity. Animals were randomly divided into five groups. Control animals received ordinary water; fluoride animals received fluoride water; all the other animals in the study received gum acacia, ascorbic acid and Ginkgo biloba for first 15 days followed by the fluoride water for 30 days. The present experiment showed fluoride caused neurodegeneration in the form of dark, pyknotic neurons could be apoptosis/ necrosis. However the neurodegeneration is less severe in the ascorbic acid and Ginkgo biloba treated animals. Hence the ascorbic acid and Ginkgo biloba may help as alternate therapeutic strategy to treat fluorosis victims.

Protective role of gallic acid on sodium fluoride induced oxidative stress in rat brain
Gallic acid is known as a potent antioxidant active compound of the edible and medicinal plant Peltiphyllum peltatum. The main objective of this study was to evaluate the neuroprotective effects of gallic acid against sodium fluoride induced oxidative stress in rat brain. Gallic acid (10 and 20 mg/kg) and vitamin C

Mitigating role of quercetin against sodium fluoride-induced oxidative stress in the rat brain
CONTEXT: Quercetin is a well known aglycone flavonoid that is widely found in different food sources. OBJECTIVE: In this study, the in vivo neuroprotective potential of quercetin against sodium fluoride-induced oxidative stress was evaluated. MATERIALS AND METHODS: Wistar rats were divided into five treatment groups and then subjected to daily

Protective effects of curcumin against fluoride-induced oxidative stress in the rat brain
We examined effects of a plant polyphenolic compound, curcumin, against fluoride-induced oxidative stress in the rat brain. Five experimental groups of male rats (10 animals each) were compared. Animals of these experimental groups were treated with curcumin (10 and 20 mg/kg body mass), vitamin C (10 mg/kg), and sample solvent

Silymarin and quercetin abrogates fluoride induced oxidative stress and toxic effects in rats
Flavonoids have been extensively studied and reported to possess widespread biological activities, including antioxidant and chelating properties. They have been proposed to exert beneficial effects in a multitude of diseased states generated due to oxidative stress. Therapeutic efficacy of oral administration of Silymarin and Quercetin after fluoride exposure (50 ppm

Cytoprotective effects of curcumin on sodium fluoride-induced intoxication in rat erythrocytes
Curcumin is well known for its potent antioxidant activity. The result of numerous studies showed that antioxidants can protect against fluoride-induced toxicity. In the present study, protective effects of curcumin against sodium fluoride-induced toxicity in rat erythrocytes were evaluated. Curcumin (10 and 20 mg/kg) and vitamin C (10 mg/kg) were

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,

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

Fluoride Is Not an Essential Nutrient
In the 1950s, dentists believed that fluoride was a “nutrient.” A nutrient is a vitamin or mineral that is necessary for good health. Dentists believed that fluoride ingestion during childhood was necessary for strong, healthy teeth. A “fluoride deficiency” was thus believed to cause cavities, just like a deficiency of calcium can

Fluoride Exposure Aggravates the Impact of Iodine Deficiency
A consistent body of animal and human research shows that fluoride exposure worsens the impact of an iodine deficiency. Iodine is the basic building block of the T3 and T4 hormones and thus an adequate iodine intake is essential for the proper functioning of the thyroid gland. When iodine intake is inadequate during infancy and
