Dental fluorosis - Wikipedia, the free encyclopedia Dental fluorosis occurs because of the excessive intake of fluoride either through naturally occurring fluoride in the water, water fluoridation, toothpaste, or other sources. Fluorosis can not occur once the tooth has erupted into the oral cavity. Dental fluorosis can be prevented by lowering the amount of fluoride intake, particularly through ingestion which has been shown controversial to even help prevent cavities. en.wikipedia.org /wiki/Dental_fluorosis   (604 words)

Fluorides and Fluoridation - Skeletal Fluorosis Production of skeletal fluorosis is influenced not only by the fluoride content of the water supplies, but also by that of food and beverages, by industrial gaseous or particulate emissions of fluoride, by the calcium and magnesium intake, and by the efficiency of the kidney function. That the incidence of endemic fluorosis is dependent to a great extent upon the hardness of water is illustrated by comparing the analyses of water constituents from the village of Bhikhi and Rajthal. Because of the lack of knowledge among physicians regarding fluorosis and its slow, insidious onset, it is impossible to estimate how many fatal cases of chronic pyelitis and paraplegia due to fluoride in water have remained unrelated to their cause. www.rvi.net /~fluoride/s10.htm   (5966 words)

Skeletal Fluorosis Study of late responses, F wave and H reflex in cases of endemic fluorosis proved unequivocally that the nerve lesion is located in the root which is responsible for the muscle involvement in fluorosis (Murthy et al 1986). A clear indication of chronic fluorosis is the calcification and ossification of ligaments and interosseous fasciae occuring along with periosteal new bone formation and development of exostoses on long bones and osteophytes in the spine. Neurological manifestations in skeletal fluorosis are secondary to compressive myelopathy. www.medvarsity.com /vmu1.2/dmr/dmrdata/cme/fluorosis/Fluorosis.htm   (9830 words)

Skeletal Fluorosis - Chemical & Engineering News In the early clinical stage of skeletal fluorosis, symptoms include pains in the bones and joints; sensations of burning, pricking, and tingling in the limbs; muscle weakness; chronic fatigue; and gastrointestinal disorders and reduced appetite. Although skeletal fluorosis has been studied intensely in other countries for more than 40 years, virtually no research has been done in the U.S. to determine how many people are afflicted with the earlier stages of the disease, particularly the preclinical stages. Skeletal fluorosis is not even discussed in most medical texts under the effects of fluoride; indeed, a number of texts say the condition is almost nonexistent in the U.S. Even if a doctor is aware of the disease, the early stages are difficult to diagnose. www.slweb.org /CEN.skeletal-fluorosis.html   (1613 words)

Fluorosis, epidemiology, indices and treatment Studies have documented that primary-tooth fluorosis does occur in areas with optimal or suboptimal water fluoride concentrations, and that in these settings primary-tooth fluorosis is most likely caused by postnatal exposures and is seen most commonly in the primary molars. The aims of this study were to determine the opinions of a group of adolescents about the cosmetic acceptability of a range of fluorosis, investigate the prevalence and severity of fluorosis in the sample and consider the extent to which fluorosis levels were related to their dental caries experience. The Fluorosis Risk Index appears to be particularly useful for analytical epidemiologic studies, because it is designed to permit a more accurate identification of associations between age-specific exposures to fluoride and the development of dental fluorosis. www.healthmantra.com /REVIEWS/fluorosis.htm   (6468 words)

The Flouride Debate | Question 19 | What is dental fluorosis?   (Site not responding. Last check: 2007-11-01) Dental fluorosis is a change in the appearance of teeth and is caused when higher than optimal amounts of fluoride are ingested in early childhood while tooth enamel is forming. Little research on the psychological effects of dental fluorosis on children and adults has been conducted, perhaps because the majority of those who have the milder forms of dental fluorosis are unaware of this condition. The type of fluorosis seen today remains largely limited to the very mild and mild categories, although the prevalence of enamel fluorosis in both fluoridated and nonfluoridated communities in the United States is higher than it was when original epidemiological studies were done approximately 60 years ago. www.fluoridedebate.com /question19.html   (1631 words)

Dental Fluorosis Dental fluorosis is an enamel defect caused by an excessive intake of fluorides during the time of enamel formation. As dental fluorosis can only occur during the stage of enamel formation it is seen by all sides as the first visible sign that an overdose of fluoride has occurred in the child during this vulnerable period. The fact that the severity of fluorosis is directly correlated to eruption of teeth, is a further sign of the implication, as since at least the 1930s has it been known that thyroid hormones control tooth eruption. www.bruha.com /pfpc/html/dental_fluorosis.html   (1194 words)

Fluorides and Fluoridation - Dental Fluorosis Although several other fluoride-induced effects might be involved in the aetiology of fluorosis, it now appears that inhibition of enzymatic degradation of amelogenins, which may delay their removal from the developing enamel and impair crystal growth, may be of critical importance. Fluoride supplements are a risk factor for dental fluorosis, though their contribution to the increase in fluorosis prevalence is less than that of water fluoridation and fluoridated dentifrices because of their more limited and shorter use. The prevalence of dental fluorosis in nonfluoridated communities ranged from 1.7 percent in 16-year-olds to 13.9 percent in 10-year-olds and, in fluoridated communities, ranged from 17.1 percent in 13-year-olds to 33.0 percent in 14-year-olds. www.rvi.net /~fluoride/s09.htm   (2412 words)

ADA.org: ADA Statement on Enamel (Dental) Fluorosis   (Site not responding. Last check: 2007-11-01) Enamel fluorosis occurs when there is a disruption in the mineralization of tooth enamel as a result of the chronic intake of too much fluoride while the enamel is forming before teeth erupt. The vast majority (94percent) of all enamel fluorosis in the United States is of the mild to very mild type which may be characterized by opaque-white, lacy markings across a tooth’s enamel surface. This type of fluorosis is not readily apparent to the affected individual or the causal observer. www.ada.org /prof/resources/positions/statements/fluoride_community_enamel.asp   (496 words)

Krass India :: Fluorosis Fluorosis is a disease caused due to excessive ingestion of fluoride. Long back it was believed that Fluorosis is a problem of elderly age group but it have been found that children in the age group of 0 to 12 years are most prone to Fluorosis as their body tissues are in formative / growth stage during this period.

Surveillance for Dental Caries, Dental Sealants, Tooth Retention, Edentulism, and Enamel Fluorosis --- United States, ... Enamel fluorosis is a hypomineralization of enamel related to fluoride exposure during tooth formation (first 6 years for most permanent teeth). A nine percentage point increase in the prevalence of very mild or greater fluorosis was observed among children and adolescents aged 6--19 years when data from 1999--2002 were compared with those from the NIDR 1986--1987 survey of school children (from 22.8% in 1986--1987 to 32% in 1999--2002) (18). Enamel fluorosis is a hypomineralization of enamel, characterized by greater surface and subsurface porosity than normal enamel, and is related to fluoride ingestion during periods of tooth development by young children (55) (first 6 years of life for most permanent teeth). www.cdc.gov /mmwr/preview/mmwrhtml/ss5403a1.htm   (9362 words)

Dental Fluorosis Dental fluorosis is an irreversible condition caused by excessive ingestion of fluoride during the tooth forming years. The damage that dental fluorosis causes to the internal matrix of the teeth is permanent. However, if the fluorosis is of a more advanced severity, abrasion is probably not a good idea as it can bring to the surface of the teeth a highly-porous enamel that will be prone to attrition. www.fluoridealert.org /dental-fluorosis.htm   (3194 words)

Skeletal fluorosis is a crippling bone disease caused by fluoride Skeletal fluorosis is characterized by hyperostosis, osteopetrosis, and osteoporosis (Obel, 1971; Shupe, 1980). Dental fluorosis is generally characterized by the presence of various enamel defects and lesions such as mottling, hypoplasia, hypocalcification and increased wear. Advanced stages of skeletal fluorosis are associated with intakes of fluoride ranging from 20 to 80 mg/day for 10 or more years (Hodge and Smith 1977, WHO 1984)." The quotes may be accurate but the statements are false. www.fluoridation.com /skeletal.htm   (2400 words)

WHO | Water-related diseases Clinical dental fluorosis is characterized by staining and pitting of the teeth. Enamel opacities similar to dental fluorosis are associated with other conditions, such as malnutrition with deficiency of vitamins D and A or a low protein-energy diet. People affected by fluorosis are often exposed to multiple sources of fluoride, such as in food, water, air (due to gaseous industrial waste), and excessive use of toothpaste. www.who.int /water_sanitation_health/diseases/fluorosis/en   (618 words)

Skeletal Fluorosis Skeletal fluorosis, especially in its early stages, is a difficult disease to diagnose, and can be readily confused with various forms of arthritis including osteoarthritis and rheumatoid arthritis. The risk of developing fluorosis, and the course the disease will take, is influenced by the presence of ceratin predisposing factors, including impaired kidney function; dietary deficiencies; gastric acidity; and repetitive stress.

Can Fluorosis Develop on Baby Teeth? Dental fluorosis is a cosmetic developmental defect of enamel that can occur when a higher than optimal amount of fluoride is ingested during the time when the enamel of teeth is developing. Dental fluorosis is a minor cosmetic effect and is not considered to be harmful to health. Fluorosis risk increases when label directions are not followed and dental products are used inappropriately. www.kidsource.com /kidsource/content5/baby.teeth.fluor.html   (516 words)

American Academy of Pediatric Dentistry - AAPD Publications   (Site not responding. Last check: 2007-11-01) A: In severe cases of enamel fluorosis, the appearance of the teeth is marred by discoloration or brown markings. In mild cases of fluorosis, the tiny white specks or streaks are often unnoticeable.

Dental fluorosis or mottled enamel manifest itself as a brown, gray or fl discolourations on the external enamel surfaces of the permanent teeth. METHODS: Fluorosis prevalence estimates were obtained from the National Survey of Oral Health in US School Children (1986-87) for the 1839 survey children aged 12 -14 years who were scored for fluorosis, had never received fluoride drops or tablets, and had lived in only one home. www.bruha.com /science/html/dental_fluorosis_ii.html   (6386 words)

The Relationship of Fluorosis and Brick Tea Drinking in Chinese Tibetans   (Site not responding. Last check: 2007-11-01) In some countries, fluorosis may be caused by excess fluoride in drinking water or by coal pollution (6-8); however, it has seldom been reported that tea drinking leads to fluorosis (9). The detectable rate of skeletal fluorosis increases with age, especially after age 30, and the detectable rate of skeletal fluorosis in Tibetan adults over 40 years of age was 50%. The index of dental fluorosis of the Tibetan children in this area was 1.33, which was graded as medium fluorosis by the classification standard of Horowitz et al. www.ehponline.org /docs/1996/104-12/cao.html   (2706 words)

Glossary: Skeletal fluorosis   (Site not responding. Last check: 2007-11-01) Skeletal fluorosis is a health effect of excessive accumulation of fluoride in bones leading to changes in bone structure and making them extremely weak and brittle. The early stages of skeletal fluorosis are characterized by increased bone mass, detectable by x-ray. The most severe form of skeletal fluorosis is known as "crippling skeletal fluorosis," which may result in calcification of ligaments, immobility, muscle wasting, and neurological problems related to spinal cord compression. www.greenfacts.org /glossary/pqrs/skeletal-fluorosis.htm   (130 words)

Fluorosis - The Perception of Dental Fluorosis : Psycho-social - Psycho-behavioural & Socio-economic Consequences   (Site not responding. Last check: 2007-11-01) Although this level of enamel fluorosis is not considered a public health problem, prudent public health practice should seek to minimize this condition, especially moderate to severe forms. In either case, it is clear that fluorosis of aesthetic concern affects a large subset of the population.

Nutrition survey in dental fluorosis-afflicted areas The incidence rates of dental fluorosis among 1,100 children from the study areas were found to differ markedly, depending on whether or not the children consumed milk. The rate of dental fluorosis of the milk-drinking group was 7.2%, whereas that of the non-milk-drinking group was 37.5% (Table 4). These results strongly suggest that inadequate intakes of protein and calcium are important factors contributing to fluorosis, and that an increase in the intakes of both calcium and protein while decreasing the intake of fluoride appears to be an important preventive medicine for the residents under study. www.fluoride-journal.com /97-30-2/302-77.htm   (1335 words)

A Close Look at Dental Fluorosis   (Site not responding. Last check: 2007-11-01) Dental Fluorosis or "mottled enamel" is a disfigurement associated with the ingestion of toxic amounts of fluorides during the period of calcification of the teeth in infancy and early childhood i.e birth to 6 years old. The permanent teeth, mainly, are affected, although dental fluorosis can sometimes appear in baby teeth.' The mottling has been described by the American Medical Association as "the most delicate criterion of harm" from fluoride and acknowledged that this will inevitably result from water containing 1 part per million fluoride. Water fluoridated at the recommended level of I part per million (ppm) used for drinking, in food preparation and manufacture, as well as in beverages, is usually the main source of fluoride intake. www.herbalfields.com /fluorosis.html   (689 words)

Fluoridated beverage consumption and dental fluorosis: There's a connection Fluoride is a mineral that protects against dental cavities; however, too much fluoride during tooth formation can lead to dental fluorosis, which is usually characterized by white streaks or splotches on the teeth. Beverage intakes and the amounts of fluoride consumed were compared between children with and those without fluorosis in their permanent incisors. The association between fluoride ingested from beverages and dental fluorosis should be carefully balanced with fluoride's benefits in preventing caries. www.eurekalert.org /pub_releases/2006-03/iaa-fbc022806.php   (734 words)

Krass India :: Fluorosis Diagnosis Fluorosis affects permanent teeth though decay of temporary teeth is also reported. Fluorosis causes internal staining of teeth, whereas other causes like Brinjal eating, Banana biting, Palm leaf biting, Coconut leaf chewing cause external staining of teeth and may be mistaken for dental Fluorosis. When sclerosis of the vertebral column is not marked, calcification of the interosseous membranes in the fore arm clearly indicate the diagnosis of Fluorosis, on radiography. www.krassindia.org /fluoride_dia.htm   (589 words)
