Abstract

The Assam region of NE India has been recognized only recently as a fluoride-affected area. Surveys indicate that one-seventh of the 700,000 people in the Karbianglong district of Assam have either dental or skeletal fluorosis. The high concentration of fluoride in the water resources in some localities such as the Ramsapathar (>20.6 mg/L) and Lungnit (>15.4 mg/L) areas of the district are of great concern. In this report we present available information concerning the waterborne fluoride scenario of Karbianglong.

  • Role of fluoride induced epigenetic alterations in the development of skeletal fluorosis.

    Highlights WGBS data depict altered methylation of genes regulating bone development pathways. Fluoride causes diminished expression of BMP1, METAP2, MMP11 and BACH1 genes. These genes play a critical role in catabolic process of skeletal development. DNA hypermethylation of these critical genes thus promote skeletal fluorosis. Fluoride is an essential trace element

  • Skeletal fluorosis causing high cervical myelopathy

    Skeletal fluorosis is endemic in some parts of the world and is the result of life-long ingestion of high amounts of fluoride in drinking water. Its clinical presentation is characterized mostly by bone and dental changes with later ossification of many ligaments and interosseous membranes. We present a rare case of high cervical myelopathy

  • Spatial distribution of endemic fluorosis caused by drinking water in a high-fluorine area in Ningxia, China.

    Endemic fluorosis is widespread in China, especially in the arid and semi-arid areas of northwest China, where endemic fluorosis caused by consumption of drinking water high in fluorine content is very common. We analyzed data on endemic fluorosis collected in Ningxia, a typical high-fluorine area in the north of China.

  • The impact of fluoride in drinking water on oral health and skeletal system of school children

    Modern life styles even among people in rural areas have created an increased demand for dental cosmetology. Dental fluorosis due to its cosmetic effect gains more public health importance today. In the scenario of increasing awareness of environmental health hazards, among people, the research into the biology of fluorosis conducted

  • Epidemiological, clinical, and biochemical study of endemic dental and skeletal fluorosis in Punjab

    The incidence of dental fluorosis in 46,000 children in the Punjab was assessed and compared with the fluoride content of their water supplies. Ten villages were selected for more detailed studies of skeletal as well as dental fluorosis. Factors other than the fluoride content of the drinking water which were found to influence

  • 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.

  • 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 & Spondylosis; Spondylitis

    Among individuals with skeletal fluorosis, the fluoride-induced changes to the spine, and the accompanying symptoms, can bear a close resemblance to spondylosis and spondylitis (as well as DISH). Spondylosis is a (non-inflammatory) degenerative disease of the spine marked by bony outgrowths (spurs) which can produce nerve cord compression. Spondylitis, by contrast, is an inflammatory form of arthritis that causes inflammation in the joints between the vertebrae. Whereas spondylosis is generally asymptomatic, spondylitis generally causes significant pain and stiffness in the spine.

  • Fluoridation, Dialysis & Osteomalacia

    In the 1960s and 1970s, doctors discovered that patients receiving kidney dialysis were accumulating very high levels of fluoride in their bones and blood, and that this exposure was associated with severe forms of osteomalacia, a bone-softening disease that leads to weak bones and often excruciating bone pain.
