Abstract
1. Twenty-three cases of fluoride osteosclerosis are presented.
2. These cases were gathered from 170,000 roentgenographic examinations of the spine and pelvis of patients living in Texas and Oklahoma where many communities have excessive fluoride content in their drinking water.
3. In each case, adequate clinical examination failed to establish any relationship between the roentgenologic findings and clinical diagnosis of the patient’s condition.
4. Fluoride osteosclerosis developing in the patient exposed over a period of many years to fluorides as high as 8 ppm, causes no harmful changes.
5. Fluoride osteosclerosis is not evidenced roentgenographically in the patient drinking water with a fluoride content of less than 4 ppm.
6. In the patient presenting roentgen evidence of sclerosis of the bone, calcification of the sacrospinous and sacrotuberous ligaments is a distinct aid in the diagnosis of fluoride osteosclerosis.

Comparison of rheumatoid (ankylosing) spondylitis and crippling fluorosis
(1) Fluoride concentrations were determined for autopsy samples of rib, sacrum, ilium, vertebra, adhering soft tissue, and rib marrow from a patient suffering from rheumatoid (ankylosing) spondylitis of 10 years’ duration. The fluoride concentrations were not increased above normal levels. In this case, the increased bone density seen in this

A case of thick but brittle bones and instant tea
CASE DESCRIPTION A 45-year-old white male was found to have radiographic findings of a diffusely dense appendicular skeleton, mild trabecular thickening, and multiple thoracic compression fractures indicating structural weakness. Bone mineral density was above the expected range for his age on the lumbar spine and femoral neck. Social history was significant

X-ray changes in the forearm and crus of residents of areas in Jilin Province with varying drinking water fluoride concentrations
GOAL: To understand the characteristics of forearm and crus X-rays of residents from areas with varying concentrations of fluoride in their drinking water, providing evidence for diagnosis of osteofluorosis. METHOD: Using quantificational epidemiological methods, a total of 15 villages from Qianan and Nonan Counties of Jilin Province were selected as the

Rapid-onset diffuse skeletal fluorosis from inhalant abuse
Case: A thirty-year-old man presented with severely debilitating left hip pain and stiffness. Radiographs demonstrated diffuse osteosclerosis and heterotopic bone formation with near ankylosis of the left hip. The patient underwent successful joint-preserving surgery to restore hip range of motion. After disclosing a history of inhalant abuse, which was confirmed

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

Skeletal Fluorosis: The Misdiagnosis Problem
It is a virtual certainty that there are individuals in the general population unknowingly suffering from some form of skeletal fluorosis as a result of a doctor's failure to consider fluoride as a cause of their symptoms. Proof that this is the case can be found in the following case reports of skeletal fluorosis written by doctors in the U.S. and other western countries. As can be seen, a consistent feature of these reports is that fluorosis patients--even those with crippling skeletal fluorosis--are misdiagnosed for years by multiple teams of doctors who routinely fail to consider fluoride as a possible cause of their disease.

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.

"Pre-Skeletal" Fluorosis
As demonstrated by the studies below, skeletal fluorosis may produce adverse symptoms, including arthritic pains, clinical osteoarthritis, gastrointestinal disturbances, and bone fragility, before the classic bone change of fluorosis (i.e., osteosclerosis in the spine and pelvis) is detectable by x-ray. Relying on x-rays, therefore, to diagnosis skeletal fluorosis will invariably fail to protect those individuals who are suffering from the pre-skeletal phase of the disease. Moreover, some individuals with clinical skeletal fluorosis will not develop an increase in bone density, let alone osteosclerosis, of the spine. Thus, relying on unusual increases in spinal bone density will under-detect the rate of skeletal fluoride poisoning in a population.

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

Similarities between Skeletal Fluorosis and Renal Osteodystrophy
It is quite possible, and indeed likely, that some kidney patients diagnosed with renal osteodystrophy are either suffering from skeletal fluorosis or their condition is being complicated/exacerbated by fluoride exposure.
