Abstract

Fluorosis in China has been known to be induced by two main causes. One is water-dependent fluorosis caused by a long-time consumption of high-fluoride (F) containing water. The other is called “coal-burning type fluorosis”, caused by inhalation of air polluted by coal smoke and/or ingestion of food exposed to coal smoke. We conducted a study on a group of Tibetan residents who regularly consumed brick tea containing high F levels. Many of the adults and children were found to be afflicted by fluorosis. Our results led us to present a third type of fluorosis in China called “brick tea type fluorosis”.

  • Skeletal fluorosis and instant tea

    Tea drinking remains popular in the United States and increasingly is suggested to promote health. We caution that skeletal fluorosis can result from consumption of excessive amounts of instant tea because of substantial fluoride levels in some commercial preparations.

  • A case of skeletal fluorosis? (Letter)

    A 79-year-old lady presented with a history of diffuse sero-negative arthritis dating from early adulthood. Numerous investigations and therapies had failed to provide any significant benefit and both knees and a hip had been replaced when initially seen a year ago. On questioning at that time, she admitted to daily

    We describe the case of a 53-year-old woman who presented with a metatarsal fracture and was found to have a bone mineral density (BMD) T-score of +11 in the lumbar spine and +7.6 in the hip. Subsequent investigation revealed very high serum, urine and tissue fluoride levels, associated with excessive

  • Dose-response relationship between skeletal fluorosis and fluoride in brick-tea

    The dose-response relationship between fluoride in brick-tea and the prevalence of skeletal fluorosis (SF) in adults was studied to determine a safe upper limit for fluoride intake from brick-tea. In brick-tea drinking endemic fluorosis areas of the Tibetan pastoral areas of Sichuan province, cluster sampling was conducted of residents above age

  • Tea Intake Is a Risk Factor for Skeletal Fluorosis

    A number of recent studies have found that heavy tea drinkers can develop skeletal fluorosis - a bone disease caused by excessive intake of fluoride.

  • 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.

  • Skeletal Fluorosis in the U.S.

    Although there has been a notable absence of systematic studies on skeletal fluorosis in the U.S., the available evidence indicates that the consumption of artificially fluoridated water is likely to cause skeletal fluorosis and other forms of bone disease in people with kidney disease and other vulnerable populations.

  • 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

  • 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.
