 (flo͝o-rō′sĭs, flô-, flō-)
An abnormal condition caused by excessive intake of fluorine, as from fluoridated drinking water, characterized chiefly by mottling of the teeth.

fluo·rot′ic (-rŏt′ĭk) adj.


(Pathology) fluoride poisoning, due to ingestion of too much fluoride in drinking water over a long period or to ingestion of pesticides containing fluoride salts. Chronic fluorosis results in mottling of the teeth of children


(flʊˈroʊ sɪs, flɔ-, floʊ-)

1. an abnormal condition caused by excessive intake of fluorides, characterized in children by discoloration and pitting of the teeth and in adults by pathological bone changes.
2. Also called mottled enamel. the changes in tooth enamel symptomatic of fluorosis.

Based on the fact that excessive exposure to fluoride causes dental fluorosis and lower amount makes toothpaste ineffective against dental caries, so the amount of fluoride in the toothpaste must be regulated.
The adverse effects of fluoride include dental fluorosis and skeletal fluorosis, and it has effects on red blood cell wall.
Dental fluorosis which manifests as discolouration of teeth and skeletal fluorosis which are endemic are most early biomarkers of fluoride toxicity.
We know that the chronic and sustained presence of the F- ion in plasma increases the likelihood of adhering to tissues in the mineralization process, (10) but there is the misperception that the hypomineralization observed in dental fluorosis is the only consequence of the excessive addition of F- in enamel.
The scope of the survey also includes a validation study of dental fluorosis diagnosis among eight years old and fluoride intake study for children of four year old.
Disruption of normal enamel formation is stated (in the 1997 report) not to be "of Public Health Significance" if the F concentration in drinking water is below 2mg/liter (2ppm), and reports of disfiguring dental fluorosis with staining and pitting of the enamel in areas with 1C.
Studies have shown that excessive ingestion of fluoride by children during their teethforming years causes dental fluorosis, an irregular mineralization of the tooth enamel marked by white spots,' explained one brand on its website.
Gupta and Ayoob apply the principles and methods of environmental engineering to the geo-genic pollution of drinking water with fluoride They cover a global perspective on fluoride in drinking water, a scenario of fluoride pollution, dental fluorosis, skeletal fluorosis, stress effects of fluoride on humans, fluoride in the environment and its toxicological effects, an overview of defluoridation techniques, and a case study of the adsorptive removal of fluoride.
63) Again, fluoridation promoters say not to worry, because the only adverse developmental effect from a chronic intake of fluoride above its UL is dental fluorosis, a cosmetic not a health issue.
Several studies in African countries have found a high prevalence of dental fluorosis even among populations that consume drinking water with relatively low fluoride content [11--14].
