fluorosis

 [floo͡″ro´sis]
a condition due to ingestion of excessive amounts of fluorine or its compounds; see fluoride poisoning.
chronic endemic fluorosis that due to unusually high concentrations of fluoride, usually in the natural drinking water supply, typically causing dental fluorosis characterized by a mottled appearance of the teeth. Combined osteosclerosis and osteomalacia can also occur in occupational exposures to vapors and dust.
dental fluorosis hypoplasia of the dental enamel resulting from prolonged ingestion of drinking water containing high levels of fluoride, manifested by the condition called mottled enamel.
skeletal fluorosis skeletal changes due to long term ingestion of excessive fluoride; they may include hyperostosis, osteopetrosis, and osteoporosis.

fluor·o·sis

(flōr-ō'sis),
1. A condition caused by an excessive intake of fluorides (2 or more ppm in drinking water), characterized mainly by mottling, staining, or hypoplasia of the enamel of the teeth, although the skeletal bones are also affected.
2. Chronic poisoning of livestock with fluorides that blacken and soften developing teeth and reduce bones to a chalky brittleness; most often caused by ingestion of forage contaminants near large aluminum plants.

fluorosis

Chronic fluoride poisoning Toxicology A chronic low-level intoxication that occurs where drinking water has fluoride > 2 ppm Clinical Weight loss, brittle bones, anemia, weakness, ill health, stiffness of joints, mottled enamel and chalky white discolored teeth with a normal resistance to caries; fluorosis is common, given flouride's availability in mouth rinses, toothpastes, misuse of fluoride treatments.

fluorosis

Poisoning with repeated large doses of the element fluorine. This may affect aluminium ore (bauxite) miners and workers involved in insecticide and phosphate fertilizer manufacture. The calcium in the bones is gradually replaced by fluorine and the bones become soft and crumbly. Abnormal bone protrusions occur and these may cause trouble, especially in the spine, where they may press on the spinal cord or nerve roots.

Patient discussion about fluorosis

Q. How do you differentiate between fluorosis and caries? Both appear as white spots on the teeth, so clinically how do you differentiate between them? I know it has something to do with their appearance while wet and dry, but I am not sure what? please help me I can't find this in any book.

A. Only mild fluorosis is seen as white stop lesion on the tooth. It usually comes with brown spots. Look for them. Another method is trying to stick a dental explorer into it (not the Microsoft one- it’ll only be a portal for viruses..) and because caries is demineralized area it will feel kind of sticky. But I wouldn’t do that…it can harm the teeth. Another way is by an x ray. Fluorosis- you will see it as a whiter spot. Caries- a more translucent spot.

In the study, dental fluorosis was not considered as a major and priority health problem by most of the groups including health extension workers.
Ultimately, drinking water below optimal fluoridation levels will reduce the effectiveness of water fluoridation, while those supplies above optimal levels may contribute to dental fluorosis. Both scenarios should be considered by medical and dental personnel when prescribing fluoride supplements or when the effects of fluoride overexposure (eg, dental fluorosis) are observed.

Higher cases of dental fluorosis amongst the population in Kelantan, Terengganu and Sabah in Malaysia have been reported.5 Fluorosis in enamel and even in dentine is caused by the ingestion of excess fluoride during tooth development.5,6 In children, exposure to high level of fluoride during tooth development can lead to dental fluorosis.7

Because exposure to high fluoride levels is a major public health problem, it is essential to assess the fluoride levels in the drinking water supply for the city of Durango, particularly because the city fluoride concentrations have not been studied, and children exhibit clinical dental fluorosis symptoms.
Consequently, a large section of the population is suffering from gastroenteritis, arsenicosis, skin lesions and dental fluorosis. Present study is based on 200 drinking water samples collected from surface and groundwater sources in nine districts of Sindh (Thatta, Jamshoro, Hyderabad, Matiari, Tando Mohammad Khan, Tando Allayar, Tharparkar, Badin and Nawab Shah).
He omits to mention that the Review explained that any reduction in tooth decay in fluoridated areas should be set against an average increase of 48% in dental fluorosis. This permanent mottling of teeth is not a mere cosmetic issue but the first outward manifestation of chronic fluoride toxicity.
