Abstract
Numerous literature sources reveal evidence that fluoride affects the activities of numerous enzymes in vitro as well as in vivo. Millions of people live in endemic fluoride areas with a severe public health problem. A plethora of data suggest that fluoride should be recognized as a developmental neurotoxicant for humans. The use of water fluoridation for the prevention of dental caries has increased the concern about adverse fluoride effects. The fluoride concentration at which a reduction in dental caries is expected is close to the level which might cause chronic pathological effects. We comment on how some of the conclusions of the recent review by Guth et al., published in Archives of Toxicology, are the emerging paradoxes in fluoride research. We show that fluoride has pluripotent effects, which might contribute to unexpected epidemics in the future.

Effects of chronic fluorosis on the brain.
Highlights Reviewing the mechanism of brain injury caused by chronic fluorosis is of great significance for protecting residents in fluorosis endemic areas. Abstract This article reviews the effects of chronic fluorosis on the brain and possible mechanisms. We used PubMed, Medline and Cochraine databases to collect data on fluorosis, brain injury,

Chronic Fluoride Exposure and the Risk of Autism Spectrum Disorder.
The continuous rise of autism spectrum disorder (ASD) prevalent in the past few decades is causing an increase in public health and socioeconomic concern. A consensus suggests the involvement of both genetic and environmental factors in the ASD etiopathogenesis. Fluoride (F) is rarely recognized among the environmental risk factors of

Fluoride Sources, Toxicity and Fluorosis Management Techniques - A Brief Review.
Highlights Overexposure to fluoride via drinking water causes several health effects including fluorosis Endemic fluorosis is still persisted in several countries even with advancement in research Most of fluorosis management techniques suggested in the past have come with their own drawbacks Defluoridation techniques based on aluminium materials pose serious

Aluminium and fluoride in drinking water in relation to later dementia risk.
Background Environmental risk factors for dementia are poorly understood. Aluminium and fluorine in drinking water have been linked with dementia but uncertainties remain about this relationship. Aims In the largest longitudinal study in this context, we set out to explore the individual effect of aluminium and fluoride in drinking water on dementia risk

Using drawing tests to measure intelligence in children from areas impacted by combined Al-F endemic toxicosis (Shuicheng, Guizhou).
Measurements of intelligence via drawing tests have been conducted to examine the intelligence development of children from regions affected by combined AIF endemic toxicosis. A selected number of 196 children between 6.5 and 12 years of age participated in the testing. Across all age groups, the average IQ level of children from

Annapolis: Water Fluoridation Linked to Death of Dialysis Patient
EVENING CAPITAL (Annapolis, Maryland) November 29, 1979 Fluoride Linked to Death by Mary Ann Kryzankowicz Staff Writer Fluoride poisoning has been definitely linked to the death of a 65-year-old kidney dialysis patient who became ill during a blood cleaning process Nov 11. State Medical Examiner Dr. (illegible) Guard has ruled that Lawrence Blake, 65, of Arundel

Fluoridation, Dialysis & Osteomalacia
In the 1960s and 1970s, doctors discovered that patients receiving kidney dialysis were accumulating very high levels of fluoride in their bones and blood, and that this exposure was associated with severe forms of osteomalacia, a bone-softening disease that leads to weak bones and often excruciating bone pain. Based on

Factors which increase the risk for skeletal fluorosis
The risk for developing skeletal fluorosis, and the course the disease will take, is not solely dependent on the dose of fluoride ingested. Indeed, people exposed to similar doses of fluoride may experience markedly different effects. While the wide range in individual response to fluoride is not yet fully understood, the following are some of the factors that are believed to play a role.

Fluoride's Direct Effects on Brain: Animal Studies
The possibility that fluoride ingestion may impair intelligence and other indices of neurological function is supported by a vast body of animal research, including over 40 studies that have investigated fluoride's effects on brain quality in animals. As discussed by the National Research Council, the studies have consistently demonstrated that fluoride, at widely varying concentrations, is toxic to the brain.
