| fluorosis | <dentistry, orthopaedics> A chronic endemic form of hypoplasia of the dental enamel caused by drinking water with a high fluorine content during the time of tooth formation, and characterised by defective calcification that gives a white chalky appearance to the enamel, which gradually undergoes brown discoloration. Excessive fluoride intake from drinking water with fluoride concentration more than 8 ppm (several cases in Spain), agricultural or industrial contamination (Texas, Arizona). Clinical features: mottling of teeth enamel. X-ray findings: thickening of bony trabecular pattern, best seen in vertebral bodies, progresses to dense uniform symmetrical sclerosis that obliterates bony architectural landmarks, marked periosteal proliferation, ligamentous calcification (especially sacrospinous, sacrotuberous ligaments) (20 Jun 2000) |

| fluosilicic | <chemistry> Composed of, or derived from, silicon and fluorine. Fluosilicic acid, a double fluoride of hydrogen and silicon, H2F6Si, obtained in solution in water as a sour fuming liquid, and regarded as the type of the fluosilicates.
