Abstract
Fluoride, a chemical compound naturally found in the environment, has been used in pharmaceutical industries, production of pesticides, and mainly added to dentifrices and public water supplies. Thus, humans might be exposed to several fluoride compounds. Despite the well known anticariogenic activity, the daily human intake of fluoridated water is extensively discussed due to the evidences of potential side effects after long-term exposure. Therefore, this chapter addresses both beneficial and detrimental effects of fluoride intake, provides relevant information on fluoride toxicity and oxidative biochemistry in living organisms, reports the pieces of evidence in literature, and emphasizes the consequences of a systemic imbalance between pro- and antioxidant agents.

Chronic fluoride toxicity and myocardial damage: antioxidant offered protection in second generation rats
This experiment was designed to investigate the extent of peroxidative changes and histological alterations in the myocardium of rats exposed to high fluoride for two generations, in addition to ameliorative role of selenium and vitamin E on the above indices. Adult albino Wistar rats were given fluoride through drinking water

Arsenic and fluoride co-exposure through drinking water and their impacts on intelligence and oxidative stress among rural school-aged children of Lahore and Kasur districts, Pakistan.
Arsenic (As), and fluoride (F-) are potent contaminants with established carcinogenic and non-carcinogenic impacts on the exposed populations globally. Despite elevated groundwater As and F- levels being reported from various regions of Pakistan no biomonitoring study has been reported yet to address the co-exposure impact of As and F- among

Neurobehavioral and neurochemical effects in rats offspring co-exposed to arsenic and fluoride during development.
Highlights Arsenic/Fluoride co-exposure during development causes neurobehavioral alterations in offspring. iAs/F causes delayed development of sensorimotor reflexes and produces less nociceptive response. iAs/F co-exposure increase locomotor activity. Antioxidant enzymes and neurotransmitter level are altered in the striatum area. Arsenic (iAs) and fluoride (F) are ubiquitous in the environment. All over

Vitamin A deficiency: An oxidative stress marker in sodium fluoride (NaF) induced oxidative damage in developing rat brain
Fluoride induced oxidative stress through depletion in levels of various anti-oxidants such as glutathione, superoxide dismutase (SOD), fat soluble vitamins (D and E) with increased levels of lipid peroxidation (LPO) and fluoride aggravate the damage in rodents as well as in humans. Vitamins A, a fat soluble vitamin possess antioxidant

Effects of long-term fluoride exposure are associated with oxidative biochemistry impairment and global proteomic modulation, but not genotoxicity, in parotid glands of mice.
Background Fluoride has become widely used in dentistry because of its effectiveness in caries control. However, evidence indicates that excessive intake interferes with the metabolic processes of different tissues. Thus, this study aimed to investigate the effects of long-term exposure to F on the parotid salivary gland of mice, from the

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,
