Abstract
Fluorotic changes in bones and joints were evaluated in 105 aluminum workers and 20 residents of an endemic fluorosis region in India. The age of the workers averaged 51.2 years, and the duration of their exposure 18.2 years. The skeletal changes in the aluminum workers exhibited the same characteristics as those of endemic fluorosis. In industrial fluorosis the changes were less advanced than in endemic fluorosis. Generalized sclerosis, alterations in the bone structure and periosteal reactions are the most typical features of skeletal fluorosis; ossification of the interosseous membranes and muscle attachments, are less characteristic.

Chronic endemic fluorosis (with bone affections) in the Punjab.
First Page of Study Since the investigation of Black an,d McKay in 1916 into the problem of mottled enamel, and the definite association of this anomaly with the fluorine content of drinking waters by Churchill (1931, 1932), the matter of fluorine intoxication has been studied in detail by different workers in

Changes in basic metabolic elements associated with the degeneration and ossification of ligamenta flava
OBJECTIVE: To determine the association between levels of basic metabolic elements and degeneration and ossification of the ligamentum flavum (LF). SUBJECTS: Fourteen consecutive patients with degenerative lumbar stenosis, 11 with ossification of the thoracic ligamenta flava, and 11 control subjects. METHODS: The basic elements of calcium (Ca), phosphorus (P), magnesium (Mg), zinc

Diagnostic criteria for endemic osteofluorosis (WS 192-1999)
According to the General Administration of Quality Supervision, Inspection, and Quarantine: National Standards Committee Proclamation (2005, No. 146), GB 16396-1996 “Clinical Diagnosis and Classification of Endemic Osteofluorosis” shall be repealed as of the date of implementation of these Criteria. These Criteria combine GB 16396-1996 “Clinical Diagnosis and Classification of Endemic Osteofluorosis”

Prevalence and estimation of the occupational risk of the musculoskeletal disorders in workers of aluminum potrooms
The aim of this research is to investigate the role of the occupational risks in the development of pain syndromes of the locomotor system in workers employed in basic workplaces at aluminum potrooms, basing on the periodic health screenings data. It has been determined that working under the conditions of

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.

"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 & 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.

Variability in Radiographic Appearance of Skeletal Fluorosis
Osteosclerosis (dense bone) is the bone change typically associated with skeletal fluorosis, particularly in the axial skeleton (spine, pelvis, and ribs). Research shows, however, that skeletal fluorosis produces a spectrum of bone changes, including osteomalacia, osteoporosis, exostoses, changes resulting from secondary hyperparathyroidism, and combinations thereof. Although the reason for this radiographic variability is not yet fully understood, it is believed to relate to the dose of fluoride consumed, the individual's nutritional status, exposure to aluminum, genetic susceptibility, presence of kidney disease, and area of the skeleton examined.

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.
