ABSTRACT

An epidemiological study was contucted on the prevalence of fluorosis in Hirakund town, an industrial town of Western Orissa and the results wer compared with two sub-urban and non-industrial town located some 80 kms away from Hirakund as control sites. Results revealed around 12-22% increase in teeth mottling (soiling) and aberration among school children in Hirakund over the control sites and 20-25% more in cattle population. Analysis of hospital records for out patients although do not reveal any admission for treatment of fluorosis, may be because of absence specialists, the admission rate with complain on teeth and bone related diseases has decline in Hirakund in comparison to the data of 2001-2002. Chi-square test indicates an association between prevalence of fluoride in environment and prevalence of fluorosis has not affected the children as only teeth abrasions have been observed which might be due to other factors like health and hygiene. In Hirakund, the level of fluoride in water is within permissible limit, which may be cause for no detectable dental or skeletal fluorosis among children excepting at the level of mild mottling or abrasion of teeth. it may be desirable to corroborate these findings with hematological studies.
