Studies on Fluorosis

Studies on Alleviation of Industrial Fluorosis in Baotou Goats

Industrial fluorosis of goats in Baotou has a history of more than 20 years. Since the 1980$ the following alleviating measures have been adopted: 1) chemical feed supplementation to counteract and reduce digestion of fluoride; 2) removal of goats from high to low fluoride areas; 3) relocation of goats from low to high fluoride areas for reproduction; 4) grass cultivation and/or low fluoride gr...

Studies on Sural Nerve Biopsies in Endemic Skeletal Fluorosis

Sural nerve biopsies from 13 patients with radiologically confirmed skeletal fluorosis were studied for myelinated fibre densities, frequency distribution of their diameters, and single teased nerve fibre preparations. It was observed that most of the biopsies showed a marked reduction in myelinated fibre densities with more than half of them involving the smaller fibres of less than 7 gm diame...

An update on fluorides and fluorosis.

Decisions concerning use of fluoride in its many forms for caries prevention are more complicated now than in the past because of the need to balance these benefits with the risks of dental fluorosis. This article reviews pertinent literature concerning dental fluorosis (definition, appearance, prevalence), pre- and post-eruptive use of fluoride, esthetic perceptions of dental fluorosis, fluori...

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...
