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.

  • Clinical effect of acupuncture on endemic skeletal fluorosis: a randomized controlled trial

    Objective. To evaluate the effect of acupuncture on endemic skeletal fluorosis (ESF) through the randomized controlled trial. Methods. Ninety-nine cases were divided into the treatment group (68 cases) and the control group (31 cases) randomly. Normal acupuncture combined with electroacupuncture was used in treatment group, while Caltrate with vitamin D tablets

  • 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

  • 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

  • Electrocardiogram analysis of patients with skeletal fluorosis

    To investigate the degree of myocardial damage resulting from endemic fluorosis, electrocardiograms of 136 skeletal fluorosis patients from an endemic fluorosis area were compared with electrocardiograms of a control group of 40 normal patients from a non-endemic fluorosis area. The results show that fluoride in drinking water consumed over time

  • Distribution of Fluoride in Plasma, Brain, and Bones and Associated Oxidative Damage After Induced Chronic Fluorosis in Wistar Rats.

    The study was aimed to determine fluoride levels in plasma, brain, and bones of Wistar rats following chronic administration of fluoride at different dose levels and the consequent oxidative damage inflicted in these tissues. Brain histomorphology and bone radiographs were also evaluated to assess the extent of damage in these

  • 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 & Spinal Stenosis

    Spinal stenosis is a narrowing of the spaces in the spine that results in pressure being placed on the spinal cord and/or nerve roots. Although stenosis can develop without symptoms, it may produce numbness, tingling, pain and difficulty in walking, as well as a heavy/tired feeling in the legs. It is estimated that 250,000 to 500,000 Americans currently have symptoms of spinal stenosis. Skeletal fluorosis is one cause of stenosis.

  • Fluoride & Osteomalacia

    One of fluoride's most well-defined effects on bone tissue is it's ability to increase the osteoid content of bone. Osteoid is unmineralized bone tissue. When bones have too much of it, they become soft and prone to fracture -- a condition known as osteomalacia. As shown below, fluoride has repeatedly been
