Chronic fluorosis.

Syndrome of Low Triiodothyronine in Chronic Fluorosis

The present study examined the thyroid function and low T3 state in a group of patients exposed to different concentration of fluoride in drinking water. 139 subjects from severe endemic fluorosis areas and 140 subjects as control group were randomly selected. The functional activity of thyroid gland was measured and the findings indicate that the level of TSH and rT3 was significantly (P<0.001...

Chronic Endemic Fluorosis (With Bone Affections) in the Punjab

Fluorosis in rats exposed to oscillating chronic fluoride doses.

Considering that blood fluoride concentration varies according to fluoride exposure and that dental fluorosis is related to the amount of enamel formed under a given fluoride dose, the present study investigated whether the fluorosis produced by an oscillating chronic fluoride dose would be similar to that caused by exposure to a constant dose, representing the mean of the oscillation during a ...

Paleopathology of skeletal fluorosis.

Skeletal fluorosis is one of a range of conditions causing excessive ossification and joint ankylosis in skeletons. It is rarely considered, however, in differential diagnoses of palaeopathological lesions. This paper considers the identification of skeletal fluorosis in a skeletal sample from the island of Bahrain, Arabian Gulf, dating to ca. 250 BC-AD 250. Approximately 4% of 255 adult skelet...
