Fluorosis, Fluorine Poisoning
Fluorosis, Fluorine Poisoning : 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).
