Relationship between fluride concentration in drinking water and DMFT indicator in 12 years old population of Germi in 2012

Abstract

One of the health issues that most people face in their lives is dental caries. Reception of a certain amount of fluoride through drinking water or other fluoride carriers reduces tooth decay by increasing the enamel resistance or decreasing its solubility. The aim of this study was to determine the relationship between the amount of fluoride in drinking water and DMFT index in 12-year-old population in 2012 in Germi. Methods: In this descriptive - cross sectional population, according to Cochran formula, 227 samples were selected by simple randomized sampling method. Data collection was checked and filled. Amount of fluoride in drinking water was determined by SPADNS method using a spectrophotometer. Results: The mean DMFT index in this study was 1.621.59 which significantly associated with tooth brushing and parent literacy level. Fluoride concentrations of drinking water in Germi was 0/62 0/09, which is lower than the standard rate. The relationship between DMFT index and fluoride concentrations of drinking water according to Pearson test was 0/21, which presents an inverse correlation between these two indices. Discussion and Conclusion: According to the World Health Organization classification, oral health level in Germi is relatively low. Average fluoride concentration of the drinking water was below the standard level in Germi.
