In a Chinese study borax was used to treat 31 patients with skeletal
fluorosis. The amount was gradually increased from 300 to
1100 mg/day during a three month period, with one
week off each month.
The treatment was effective with 50 to 80% improvement.

“Endemic skeletal fluorosis is a disease caused by excessive ingestion of fluoride through water, food, air or medicine. The upper limit of optimum fluoride level in drinking water for a tropical country like India is 0.5 ppm. The upper limit of safe total intake of fluoride from food and water per day for an adult is 5 milligrams (WHO-2002)”.
The TOTAL daily intake through water and food determines the development of fluorosis. First ever cases of endemic skeletal fluorosis and its neurological manifestations in the world were recorded from Podili, Darsi and Kanigiri areas of Andhra Pradesh in 1937. Subsequently cases of fluorosis were recorded from Nalgonda and other areas of the Andhra Pradesh state and other parts of India.
It is now estimated that 60 million people are living in these endemic areas and are at risk of contacting the disease and 2 million people are crippled because of it. The incidence of fluorosis affected districts in India are listed alphabetically: Assam2; Andhra Pradesh= 17; lBihart=8; Delhi4; Gujarat= All except Dang; Haiyana 12; Jammu & Kashmir=1; Kamataka 14; KeraI=3; Maharashtra= 10; Madhya Pradesh= 10; Orissa= 3; Punjab=13; Rajasthan= All 32 districts; Tamil 4adu 8; Uttar Pradesh= 7 and West Benga=4. Hence, skeletal fluorosis continues to be a major public health problem in India.
The factors, which govern the development of fluorcsis, are the following:
1. High levels of fluoride in drinking water supplies and in the foodstuffs grown in these endemic areas.
2. Tropical weather and hard manual labor by affecting the intake of water.
3. Poor nutrition: Diets deficient in calcium, magnesium and vitamin ‘C’ aggravate fluoride toxicity. High intake of calcium reduces the amount of absorbed into the bones. Magnesium has peculiar relationship with fluoride and its optimum intake helps in elimination of fluoride from the body. Vitamin ‘C’ is beneficial in some way in reducing fluoride toxicity. Diets deficient in calories and calcium intake increase the incidence of fluorosis (WHO-2002).
4. Renal disease aggravates fluorosis by increased deposition of fluoride in the bones.
A diseased kidney cannot handle fluoride excretion from the body and hence its increased deposition in the bones.
5. Presence of abnormal amounts of certain trace elements in the drinking water supplies such as strontium, uranium etc. Strontium levels in drinking water supplies in some endemic areas are high and strontium is a bone-seeking element like fluoride and both these aggravate the bony changes.
In a study of 94 drinking water samples from the endemic fluorotic villages of Prakasam and Nalgonda districts the fluoride and strontium levels are as follows: Fluoride levels ranged between 0.1 to 9.5 ppm for a mean of 2.009 ppm and strontium levels ranged between 4.91 to 9931.74 ppb for a mean of 1670.02 parts per billion. Any water strontium levels of over 1000 ppb are suspect. Increased levels of fluoride and strontium appear to playa role in the severe forms of fluorosis that is witnessed in some endemic areas of fluorosis in Andhra Pradesh especially in Prakasam where fluoride levels are not very high. Some elements like uranium are nephrotoxic and may aggravate fluorosis problem. Levels of trace elements such uranium, selenium, zinc, iron, lithium, lead, barium, aluminum etc were in abnormal concentrations in some of the drinking water supplies of villages in Prakasam and Nalgonda districts of Andhra Pradesh. Aluminum is known to increase fluoride absorption from the gut and hence its abnormal concentration in water supplies is harmful. The role of these other elements except those of strontium, aluminum and uranium in fluoride metabolism are not known at present time.
De fluoridation plants are based on adding aluminum compounds to the water containing high levels of fluoride. It may be noted hundreds of crores of rupees were spent on erecting these plants in 1980’s 1990’s and not a single one of them are working now. So is the fate of household de fluoridation units. Besides there is the risk of increased intake of aluminum which is being incriminated for the causation of Alzheimer’s disease as well as motor neuron disease for which there is no therapy like AIDS disease. Tea contains exceptionally high content of fluoride and each cup may add up to 2 milligrams of fluoride. Ideal solution for skeletal fluorosis is its prevention by providing safe drinking water and providing such water for cultivation of crops in these endemic areas. This appears to be only a very distant dream. Government of India envisaged health for all by 2000 in 1987 AD and planned provision of safe drinking water to all villages by that date. The plans failed miserably and now the authorities have become more pragmatic. One’ of the ‘millennium development goals’ of 2002 is to provide safe drinking water to half the rural population by 2015. Hence prevention of fluorosis is not possible in the near future and at least efforts must be made to lessen the suffering of the people by improving their nutrition.
The situation in certain parts of Andhra such as Nalgonda is very grim. When Daver first recorded cases of skeletal fluorosis from this region in 1945 AD and by Siddique in 1955 AD, there were no children with deformed limbs. These cases with deformed limbs were recorded in 1970’s. Rural nutrition in the past few decades has gotten worse in many parts of state and in other parts of the country. National institute of nutrition conducted surveys of status of rural nutrition in 715 villages of seven states in 2002 and 2003. Eighty villages in AP were studied and AP has the distinction of having highest incidence of dental fluorosis among seven states. The results of nutrition study are contained in National nutrition monitoring bureau reports 21 and 22, which reveal the appalling state of nutrition of rural population in the country. Sixty percent of the children below 6 years of age are malnourished and a third of them suffer from severe under weight problem. Only a third of the children studied were getting an optimum diet. Calcium intake is exceptionally low in all states and calcium does playa big role in Nalgonda having very high incidence of skeletal fluorosis in our country. Drinking water supplies of Nalgonda have a high content of fluoride because the calcium content of Nalgonda soils and rocks is low. This allows more fluoride to seep in to the water supplies (Netherland study- 1986). Siddiqui study revealed that avenge daily intake of calcium in Nalgonda individuals was only 300mg whereas it was 900 mg in Punjab. NNMB report of 2002 reveals that calcium intake of rural population is appallingly low inAndhra and hardly averages around 300 milligrams whereas it should be around 800-1000 milligrams in growing children. Hence, there are no children with deformed limbs in Punjab villages with simdar levels of fluonde in drinking water supplies. Nutrition status study of 50 children in Sharbanapuram village of Aler Mandal of Naigonda revealed that only one boy was normal as per BMI and percentile studies. Mid day meal scheme has not helped these children in Nalgonda in this regard. Children hardly get 300 calories of diet and most of the times the food supplied is not even hygienically good. National family health survey-Ill by the government of India in 2006 in 29 states revealed that 45 % of the children below are undernourished and 57 % of women are anemic. All government policies to improve nutrition of rural folk have been a dismal failure so far.
What needs to be done? One has to pragmatic. Ideal way would be to supplement the diet of children in the endemic areas with calcium, magnesium and vitamin C. This was also the basis of Chinese research work in early 1990’s. The best way would be to give a glass of milk and a banana to every school- going child in these endemic areas. Milk is perishable and can be adulterated. A pouch containing 300 ml of milk becomes very expensive. A tablet containing 5,0 milligrams of calcium, 300 milligrams of magnesium and 40 milligrams of vitamin C with vitamin D to improve absorption of calcium would be cheap and practical in addition to midday meal scheme, which needs to be improved. Since anemia is widely prevalent in rural population it may be advisable to add iron also to this tablet. The skeletal fluorosis was discovered in our country in Prakasam district seventy ears ago and this continues to be major health problem even today. All efforts to contain this disease have jbeen a dismal failure so far. Unless pragmatic steps are taken this problem going to affect the lives of millions of people in our country for a long time to come.
There are three factors for the causation of skeletal fluorosis, Water, food and nutrition. Ask for Krishna water for drinking and cooking for every fluorotic village. Try for Krishna water for cultivation in future. Improve the nutrition of the population especially those of growing children by whatever means practicable. Avoid drinks such as tea, which is very rich in fluoride and also seafoods. Avoid analgesics, which could damage the kidneys and aggravate the problem in these areas where studies reveal a higher incidence of kidney disease.
PREFERRED FOODS IN FLUOROTIC REGIONS
A diet rich in calcium, magnesium and vitamin ‘C’ would greatly benefit the population living in areas where soil and water fluoride levels are high while measures to provide safe drinking water could benefit by reducing fluoride intake,
a diet enhancing calcium, magnesium and vitamin C intakes would considerably reduce the basic pathology associated with fluorosis. However these food sources should be grown in no fluoride areas and provided for consumption in region with fluorosis.
Though there are several food sources only those which are commonly consumed in region of AP and which are affordable to the lower socio-economic groups are suggested. The resource for this compilation is the:-
Dental Fluorosis in Australia
is the visible mottling of teeth (see photos above).
IT IS A PATHOLOGICAL CONDITION – IT AFFECTS HUMANS AND ANIMALS.
RECORDED ON THE TEETH OF MEXICANS IN 1888
Dental fluorosis also indicates the deposition of fluoride in the bones – skeletal fluorosis, causing brittleness in later life, – especially hip fractures in humans. It can occur after teeth formation but will NOT be recorded on the teeth after they are formed. Dental fluorosis is not reversible and in more severe cases, causes disfigurement, pitting, staining, positional defects, (malocclusion) brittleness, and facilitates decay.
In these cases fluoride causes the exact problem it is supposed to prevent.
The eruption of teeth, animal and human, is delayed in the presents of fluorides.
This delay accounts for the original statistical error – inferring that fluoride reduces decay in children’s teeth –[it just] skews the data…
MORE ON DELAYED ERUPTION
The fallacy on which the claim that fluoridation reduces dental decay relies almost exclusively on the direct comparison of the raw data on the prevalence of dental caries in 5 year-old children in fluoridated and unfluoridated areas. Indeed, in some locations – but by no means all – there may appear to be a slight difference, but this vanishes entirely in older children who have their permanent teeth. Predictably, pro-fluoridation lobbyists invariably avoid referring to this far more relevant age group in their attempts to convince listeners of the supposed beneficial effects of fluoride. Making a direct comparison of children’s teeth is difficult because there are many things that can affect a child’s dental health. But the greatest problem with this comparison is that fluoridation inhibits the rate at which the teeth of young children emerge from their gums. The delay may be from a few months to well over a year, so in fluoridated areas, the teeth of young children are fewer in number, and younger, than those of children in unfluoridated areas. This renders any comparison of crude data on dental decay in children of the same age completely unscientific and misleading – in scientific terms, it is a comparison between unmatched samples, and entirely meaningless. It is therefore improper to compare the dental health of same-age young children, because the effects of fluoridation must be compared on teeth of the same dental age, and not simply according to the chronological age of the children themselves...
