Abstract
Dental fluorosis (DF) is a tooth malformation related to ingestion of high amount of fluoride (F) during tooth development. According to various surveys (1994 , 2000 & 2002), it is clearly established that DF has increased incidences rates in the areas with fluoridated water ranging from 7.7% upto 80.9% and only 2.9% to 42% in areas without fluoridated water. It was being observed that 10-20% of the rural population reported to department with dental fluorosis belonged to non-fluoridated areas. Several studies suggested that there was a weak corelationship between drinking water & DF severity. Aim: The present study was undertaken to investigate prevalence of dental fluorosis and hereditary patterns of dental fluorosis in identified individuals among rural population in vicinity of Nagpur district. Materials and Methods: A case control study was conducted at six rural places around Nagpur. The fluoride content was estimated from sample of drinking water from well and tap.384 individuals were selected using systematic random sampling method. A detailed case history was taken followed by reporting of DMFT and DMFS indices. The collected data was analyzed statistically using students’t test. Results: All the water samples tested reported F concentration varying with 0.267 to 1.081mg/ml. Prevalence of DF for individuals consuming well water(62.1%) was found to be significantly higher(p Conclusion: There was no correlation with DF and F concentration in drinking water, however its strong correlation exists with genetic component. Keywords: Dental fluorosis (DF)
Highlights
Dental fluorosis (DF) is a tooth malformation produced by chronic ingestion of fluoride (F) during tooth development that primarily affects enamel but can affect dentin
Fluorosis is a result of destruction of metabolic calcium & A survey was conducted at six rural places around Nagpur. phosphorus, leading to inhibition of active enzymatic Sample of drinking water from well and tap was collected process in human body, which interrupts the function of for estimation of fluoride content
DF has increased in areas with fluoridated water by 7.780.9% and 2.9-42% in non fluoridated water areas10-20% of the rural population reported to our department with DF belonged to non-fluoridated areas
Summary
Maximum permissible limit 1.5 to 1.0 ppm for for estimation of pH and fluoride concentration using ion. In Vidarbha region of Maharahtra, exchange method at (NEERI), Nagpur. Chandrapur, Gondia, Amravati & Gadchiroli was statistically analyzed using Chi square test. Reported F concentration of 1.51-4.01 mg/L in ground water. DF has increased in areas with fluoridated water by 7.780.9% and 2.9-42% in non fluoridated water areas10-20% of the rural population reported to our department with DF belonged to non-fluoridated areas. Several studies suggested that there was a weak co-relationship between drinking water & DF severity.[9,10]
