  • Title: Osteo-dental fluorosis in relation to chemical constituents of drinking waters.
    Author: Choubisa SL.
    Journal: J Environ Sci Eng; 2012 Jan; 54(1):153-8. PubMed ID: 23741872.
    Abstract:
    Study was conducted in 17 fluoride endemic villages to find out association between the prevalence and severity of osteo-dental fluorosis with different chemical constituents of drinking waters. These villages were arranged in 7 sets, each containing 2 to 3 villages with identical mean fluoride (F) concentrations in the range 1.0 to 5.8 mg/L but having different mean values of total hardness, alkalinity and nitrate (NO3) content in drinking water sources. A close association or relationship was found between the prevalence of fluorosis and the total hardness and alkalinity of potable waters. A low prevalence of fluorosis was found at low alkalinity and at high total hardness. But no specific association was observed between the prevalence figures of fluorosis with pH and NO3 levels which is also discussed in the present communication.
