Endemic fluorosis in southern Rajasthan, India

Abstract: SUMMARY: Chronic fluoride intoxication in the form of osteo-dental fluorosis was investigated in 21 villages of Banswara, Dungarpur, and Udaipur districts of southern Rajasthan, where fluoride (F) concentrations in drinking waters range from 1.5 to 4.0 ppm. Interestingly, a variable prevalence of fluorosis was observed in villages having almost the same F concentrations. At 1.5 ppm, 21.3, 25.6, and 38.9% of children and 33.3, 36.9, and 44.8% of adults in differ- ent villages of these districts were found to be affected with dental fluorosis. The maximum prevalence of dental fluorosis (77.1%) was found in the 17-22 year age group. No significant correlation was found between prevalence fig- ures and gender. At this 1.5 ppm F concentration, 6.1, 6.8, and 9.5% of adults in villages of Banswara, Udaipur, and Dungarpur districts, respectively, showed evidence of skeletal fluorosis. Subjects of these districts showed the highest prevalence of skeletal fluorosis, 32.8, 36.6, and 39.2% at maximum F level of 3.7 ppm, 4.0 ppm, and 3.2 ppm, respectively. No children were found affected with skeletal fluorosis or skeletal deformi- ties, the prevalence of which was higher in males and increased with age and higher F level. Deformities such as crippling, kyphosis, and genu varum were observed most frequently in higher age groups (>40 years) at a F concentra- tion of 2.8 ppm or higher. None of the fluorotic subjects showed evidence of goitre (thyroidism) or genu valgum syndrome. Radiological findings of other deformities in fluorotic subjects were also found. Possible factors responsible for a higher prevalence of fluorosis in villages having similar F concentrations are discussed.

Well water fluoride, dental fluorosis, and bone fractures in the Guadiana Valley of Mexico

Abstract: SUM ARY: In the Guadiana Valley (lhe city of Durango and its suBoundings in nor0rweslern ftlexho), the drinking water supply comes ftom underground wells and is chalacnerized by a high content of f,uofile. ]n this study, a quantitative assessment of dental fluorcsis was made in the school age (5-12 years) and adult (1360 parc) population of Guadhna valley tfirough a multistage sampling by conglomerdes of the Population. The Dean index of dental fluo' rosis was colre|ad witt the fluoride concentration in drinking water. In those pads of lhe valby with fluoride concentratiorc higher than 12 mg/L, all the children surveyed efi3biH dental fluorosis, ard 350/6 of them had suffered serious damage to their teeth. A linear correhion beiureen the Dean index of dental fluorosis and the frequency of bone fracttles was also observed among both chiHr€n and adults.
