Abstract

The study comprised 46 children (25 boys and 21 girls) aged 10 to 14 years with endemic mottled enamel. From birth all children used aqueductal potable water containing supraoptimal amount of fluorine equal to 2,68 mg/ml. The control group consisted of 40 children from Lód? children care homes free from mottled enamel in whom endogenic fluoridation has been performed using Fluodar tablets according to generally accepted instructions. In both groups of children the fluorine content in the blood serum and urine has been determined. The children with mottled enamel the fluorine excretion with urine was statistically significantly higher than in the control group. Moreover, the children with mottled enamel showed higher concentration of fluorine in the urine than in the serum whereas in the control group the fluorine concentration in the urine and in the serum were almost identical.

    Abstract The study was undertaken to determine serum/urinary fluoride status and comparison of free T4, free T3 and thyroid stimulating hormone levels of 8 to 15 years old children with and without dental fluorosis living in an endemic and non-endemic fluorosis area. A sample group of 60 male and female school children,

  • Biomarkers for the Assessment of Fluoride Exposure in Children.

    Due to practical difficulties in quantifying fluoride exposure, the ability of various biomarkers to predict exposure has been investigated previously. However, the results are inadequate for validation of their application and usefulness. This study aimed to investigate the association between contemporary/recent biomarkers of fluoride exposure and total daily fluoride intake

  • Studies on fluorosis in Mehsana District of North Gujarat.

    A survey was conducted in eighteen fluoride endemic villages in Mehsana District of North Gujarat (India). The individuals afflicted with fluorosis were examined for apparent mottled teeth and skeletal complications. Samples of urine and blood of these individuals along with drinking water were collected and compared with samples obtained from

    Chronic exposure to fluoride is a public health problem worldwide. We explored the relationship between fluoride exposure, orthopedic injuries and bone formation markers alkaline phosphatase (ALP), bone Gla protein (BGP) in participants with coal-burning fluorosis in Hehua Village (coal-burning fluorosis endemic area) in Zhijin County of Guizhou Province and Zhangguan

  • Fluoride, Thyroid Hormone Derangements and its Correlation with Tooth Eruption Pattern Among the Pediatric Population from Endemic and Non-endemic Fluorosis Areas.

    AIM: To comparatively evaluate the status of fluoride in the body with thyroid activity in the pediatric population of endemic fluorosis areas. The present study also attempted to elucidate whether any correlation exists between fluoride and thyroid hormone derangement with delayed tooth eruption. MATERIALS AND METHODS: A total of 400 pediatric

  • Dental Fluorosis Is a "Hypo-mineralization" of Enamel

    Teeth with fluorosis have an increase in porosity in the subsurface enamel ("hypomineralization"). The increased porosity of enamel found in fluorosis is a result of a fluoride-induced impairment in the clearance of proteins (amelogenins) from the developing teeth. Despite over 50 years of research, the exact mechanism by which fluoride impairs amelogin

    The traditional criteria (the "Dean Index") for diagnosing dental fluorosis was developed in the first half of the 20th century by H. Trendley Dean. While the Dean Index is still widely used in surveys of fluorosis -- including the CDC's national surveys of fluorosis in the United States -- dental

  • "Mild" Dental Fluorosis: Perceptions & Psychological Impact

    The vast majority of research has found that patients, parents, and the general public alike view mild fluorosis (TF score 3) as a significant blemish of the teeth, one that is likely to embarrass the affected child to a degree that cosmetic treatment would be warranted.

  • Physician's Desk Reference: Fluoride Hypersensitivity

    The following are excerpts from various editions of the Physicians' Desk Reference (PDR). "In hypersensitive individuals, fluorides occasionally cause skin eruptions such as atopic dermatitis, eczema or urticaria. Gastric distress, headache and weakness have also been reported. These hypersensitivity reactions usually disappear promptly after discontinuation of the fluoride. In rare cases,

  • Moderate/Severe Dental Fluorosis

    In its "moderate" and severe forms, fluoride causes a marked increase in the porosity of the enamel. After eruption into mouth, the porous enamel of moderate to severe fluorosis readily takes up stain, creating permanent brown and black discolorations of the teeth. In addition to extensive staining, teeth with moderate to severe fluorosis are more prone to attrition and wear - leading to pitting, chipping, and decay.
