Excerpt:
The present study was carried out during May 2010 to December 2011 in three villages which were randomly selected from Warora tehsil of Chandrapur district which is one of the endemic district of Maharashtra. . . . All the presently available ground water samples were collected and the mean fluoride concentration was estimated by the ion analyser method, varied from 0.73 to 2.80 mg/L compared to the recommended maximum permissible limit of 1.5 mg/L.
As seen in Table 5 a high prevalence of skeletal fluorosis was observed from habitual users of black tea and tobacco [11.91% – 19.85%] whereas a relatively very low prevalence [3.72% – 7.1%] of fluorosis was observed among non-users. . . . Over 90% of the people affected with severe fluorosis belongs to the low socio-economic status and they had generalized nutritional deficiencies.
In the present clinical examination it was observed that the most common symptoms joint pain (35.75%), back pain (29.01%) and other symptoms like tingling and numbing of extremities, shoulder pain, neck pain and stiffness are the symptoms of skeletal fluorosis. Earlier investigators found that back pain (68%), joint pain (22%), pain or stiffness in the backbone and hip (16.2%) and pain or stiffness in joints and backbone (15.5%) and back pain (73%) and neck pain (34%). The common symptoms are pain in the neck and back associated with rigidity, joint pains and paraesthesia of the limb.

Non-Endemic Skeletal Fluorosis: Causes And Associated Secondary Hyperparathyroidism (Case Report and Literature Review).
Highlights Fluorocarbon “huffing” is an under-appreciated cause of skeletal fluorosis (SF) We present a SF case with hyperparathyroidism, osteosclerosis, and osteomalacia SF may go undetected due to variation in symptoms, radiology, and biochemistry Dietary calcium, prior bone health, and skeletal F exposure influence SF features SF is common in

Skeletal fluorosis from instant tea
INTRODUCTION: Skeletal fluorosis (SF) can result from prolonged consumption of well water with >4 ppm fluoride ion (F(-); i.e., >4 mg/liter). Black and green teas can contain significant amounts of F(-). In 2005, SF caused by drinking 1-2 gallons of double-strength instant tea daily throughout adult life was reported in

Fluoride exposure and bone status in patients with chronic intestinal failure who are receiving home parenteral nutrition
BACKGROUND AND OBJECTIVE: Metabolic bone disease is frequent in chronic intestinal failure. Because fluoride has a major effect on bones, the status of both fluoride and bone was studied in long-term home parenteral nutrition (HPN) patients. DESIGN: We studied 31 adults aged (x +/- SD) 56.3 +/- 15.1 y, mainly

Brick tea fluoride as a main source of adult fluorosis
An epidemiological survey was conducted in Naqu County, Tibet in September 2001 to investigate the manifestations of fluorosis in adults caused by the habitual consumption of brick tea. Profiles were obtained for the total daily fluoride intake, environmental fluoride levels and average urinary fluoride concentration, and a physical examination and a

Fluoride-related bone disease associated with habitual tea consumption
Acquired osteosclerosis is a rare disorder of bone formation but an important consideration in adults with sclerotic bones or elevated bone density results. In such patients, malignancy, hepatitis C, and fluorosis should all be considered when making a diagnosis. We describe 4 patients evaluated at our Metabolic Bone Disease Clinic

Fluoride & Osteoarthritis
While the osteoarthritic effects that occurred from fluoride exposure were once considered to be limited to those with skeletal fluorosis, recent research shows that fluoride can cause osteoarthritis in the absence of traditionally defined fluorosis. Conventional methods used for detecting skeletal fluorosis, therefore, will fail to detect the full range of people suffering from fluoride-induced osteoarthritis.

Mayo Clinic: Fluoridation & Bone Disease in Renal Patients
The available evidence suggests that some patients wtih long-term renal failure are being affected by drinking water with as little as 2 ppm fluoride. The finding of adverse effects in patients drinking water with 2 ppm of fluoride suggests that a few similar cases may be found in patients imbibing 1 ppm, especially if large volumes are consumed, or in heavy tea drinkers. The finding of adverse effects in patients drinking water with 2 ppm of fluoride suggests that a few similar cases may be found in patients imbibing 1 ppm, especially if large volumes are consumed, or in heavy tea drinkers and if fluoride is indeed the cause. It would seem prudent, therefore, to monitor the fluoride intake of patients with renal failure living in high fluoride areas.

Fluoride Content of Tea
Tea, particularly tea drinks made with lower quality older leaves, contain high levels of fluoride. Because of these high levels, research has found that individuals who drink large amounts of tea can develop skeletal fluorosis -- a painful bone disease caused by excessive fluoride intake. Since skeletal fluorosis is often misdiagnosed by

Exposure Pathways Linked to Skeletal Fluorosis
Excessive fluoride exposure from any source -- and from all sources combined -- can cause skeletal fluorosis. Some exposure pathways , however, have been specifically identified as placing individuals at risk of skeletal fluorosis. These exposure pathways include: Fluoridated Water for Kidney Patients Excessive Tea Consumption High-Fluoride Well Water Industrial Fluoride Exposure Fluorinated Pharmaceuticals (Voriconazole

Nutrient Deficiencies Enhance Fluoride Toxicity
It has been known since the 1930s that poor nutrition enhances the toxicity of fluoride. As discussed below, nutrient deficiencies have been specifically linked to increased susceptibility to fluoride-induced tooth damage (dental fluorosis), bone damage (osteomalacia), neurotoxicity (reduced intelligence), and mutagenicity. The nutrients of primary importance appear to be calcium,
