@article{Ambarkova_2018, title={Correlation between DMFT of 12-year-old children and concentration of fluorine in drinking water from the Vardar region of the Republic of Macedonia}, volume={10}, url={https://www.id-press.eu/aph/article/view/2236}, abstractNote={<p>The aim of this study was to determine the correlation between DMFT (decayed, missing and filled teeth) index of 12-year-old children and the concentration of fluorine in drinking water from the areas where children live. Material and methods: The study included 85 children from 2 central and 2 regional primary schools, in whom DMFT index was determined. The children live in 2 different cities and 2 different villages. Four water samples were taken from the examined areas to determine the fluorine concentration by electrochemical method using pH / ISE meter-Thermo-Orion with a special F-electrode (Thermo Orion Ion Plus Fluoride Electrode) at the Institute for Public Health. Spearman"˜s method was used to determine the correlation between the specified variables. Results: The total number of children in the examined sample was 85, of which 45 (52.94%)   were male and 40 (47.06%)   were female. The average DMFT index in this group of children was 2.75  with a standard deviation of ± 2.56. Maximum concentration of fluorine in drinking water of 0.39 ppmF was determined in the village Vinichani, while minimum (0.17 ppmF)  in the city of Veles and (0.20 ppmF) in the village of Melnica. Correlation of DMFT index in the 12-year-old children from  the Vardar region and the concentration of fluorine in the drinking water had a negative, indirect correlation, with the value of the coefficient r  =- 0,393. Conclusions: The correlation between DMFT index and  the concentration of drinking water is a negative, indirect and highly statistically significant (p<0.01).</p>}, number={2}, journal={Archives of Public Health}, author={Ambarkova, Vesna}, year={2018}, month={Nov.}, pages={5–13} }
