Fluorosis

 

a chronic disease caused by prolonged excessive ingestion of fluorine. The consumption of water with a high fluorine concentration (more than 1–1.2 mg/liter) or food with an excessive quantity of fluoride compounds results in the retention of fluorine salts in bones and dental tissues and the replacement of soluble calcium compounds by the insoluble compounds of calcium and fluorine. Fluorosis is manifested by the appearance of stains on dental enamel and by a change in the structure of bony tissue (osteosclerosis), causing bone deformity and calcification of ligaments. When contact with fluorine is terminated, symptoms of fluorosis decrease.

It is suggested that in the face of low dietary intakes, the increased calcium requirements associated with the increased mineralization of fluorotic bone may induce reduce 25(OH)D concentrations which together with the low calcium intakes induce rickets (27).
For bio-monitoring of fluorosis patients, fluoride levels were determined in drinking water and human urine samples of different individuals having dental fluorosis and bony deformities from fluorotic area of Punjab (Sham Ki Bhatiyan, Pakistan) and then compared with reference samples of non fluorotic area (Queens Road, Lahore, Pakistan) using ion selective electrode methodology.
It should be noted that all these methods, discussed above, have mainly been studied in diffuse fluorotic opacities or post-orthodontic white spots, therefore their application to hypomineralised MIH enamel should be with caution.
