Aim: To estimate fluoride concentration in drinking water, cowâ€™s milk and buffaloâ€™s milk and to correlate the concentration of fluoride in cowâ€™s milk and buffaloâ€™s milk with varying levels of fluoride concentration in drinking water.
Materials and Methods: Ten households having both cows and buffalo's were selected by convenience in each of the 3 zones (below optimum fluoride <0.7 ppm (parts per million), optimum fluoride 0.7-1.2 ppm and above optimum fluoride areas > 1.2 ppm). From these selected households, 200 ml of fresh milk of both cows and buffaloes was collected along with 200 ml of drinking water for estimation of fluoride concentration by using a fluoride ion selective electrode method. The data was analysed using SPSS, version 11.5 for windows.
Results: The mean fluoride concentration of drinking water, cowâ€™s milk and buffaloâ€™s milk in three different fluoride zones was 0.89Â±0.39, 0.09Â±0.07, 0.09Â±0.08 respectively. Pearsonâ€™s correlation found a statistically significant correlation between fluoride concentrations in cowâ€™s and buffaloâ€™s milk with varying levels of fluoride concentration in drinking water in zone B and zone C. However, this correlation was not statistically significant in zone A.
Conclusion: With an increase in fluoride concentration in drinking water there was an increase in concentration of fluoride in cowâ€™s and buffaloâ€™s milk. We conclude that this association is seen in conjunction to not only a single factor but rather due to culmination of several other aspects. So, there is a need to elucidate the other factors that might be contributing to this increase and dental fluorosis.
