Fluoride; dmft Index; DMFT Index; Oral Epidemiology Introduction Dental caries is an ancient disease that dates back to the time when agriculture replaced the hunt as the main source of food, although its prevalence and severity were at much lower levels in that time compared to prevalence of dental caries today. Although recent studies show a decline in the dental caries trend in most developed countries, which are mainly attributed to the use of fluoride in various forms [1] dental caries is still significant presence in many underdeveloped and developing countries, such as African and Asian countries, Citation: Ambarkova Vesna. “The Correlation between the dmft/DMFT Index of 6-Year-Old Children and the Concentration of Fluorine in Drinking Water from the South-East Region of the Republic of Macedonia”.

The Correlation between the dmft/DMFT Index of 6-Year-Old Children and the Concentration of Fluorine in Drinking Water from the South-East Region of the Republic of Macedonia 1206 including India due to lack of public awareness and motivation, inadequate resources for sophisticated dental treatments and changing history of public health. eating habits [2]. Indeed, the use of fluoride has been recognized as one of the most successful measures to prevent dental caries in the countries. This is seen in children by the systematic continuous reduction of dental caries and the constant increase in the number of In recent years, a significant reduction in the prevalence of oral diseases has been observed in several western highly industrialized children without caries. This is due to the changed lifestyle and living standard, a more cautious approach to the consumption of sugars, - dation [3]. improved practice of oral hygiene, the use of fluoride in toothpastes, the use of fluoride mouthwashes, and the application of local fluori All oral diseases have similar risk factors. These are the four most common chronic diseases: cardiovascular diseases [4], cancer [5], chronic respiratory diseases [6] and diabetes [7], including dieting deterioration of health status [8], tobacco use [9] and alcohol abuse. Inadequate oral hygiene is also a risk factor [10-12]. The need for genetic studies to identify genes and genetic markers of diagnostic, prognostic and therapeutic values is particularly prominent in the last decade. Caries human genetic studies are very important for better understanding and treatment for the most preva- lent bacteria-mediated non-contagious disease in the world-dental caries [13]. The Southeast region is one of the eight statistical and planning regions of Macedonia. This region borders with the Vardar and Eastern regions. The region covers the Strumica-Radovish and Gevgelija-Valandovo valleys, i.e. the drainage area of ​​the Strumica river and the lower catchment area of ​​the river Vardar. Its surface is 2,739 square kilometers or 11 percent of the territory of the Republic of Macedonia. There are ten municipalities in this region. In 2011, 8.4% of the population of the Republic of Macedonia lives in this region. The density of the population is 63.2 people per km2, and it is valid for a well-developed region in our country where the unemployment rate is only 9.3 [14]. Macedonia. In the Southeast region, the water supply is performed by the public enterprises: Utility Service - Bogdanci, Public Utility In the Southeast region, according to the 2002 census, there are 171,416 citizens or 8.47% of the total population of the Republic of Service “Communal Services” - Valandovo, JKP “Komunalec” - Gevgelija, JKP “Komunalec” - Polin-Star Dojran, PE “Progres” -Radovis, JKP “ Komunalec “- Strumica. In the area of the municipality of Strumica there are 25 villages. The villages Bannica and Gabrovo are connected to the water supply system in 2011, the villages of Gorni Baldovci from March 2010, while the villages Bansko, Dabile, Dobreci, Kuklis, Murtino and Sachevo from 2009. In 2008, the villages Svidovica, Prosenikovo, and the village of Vodoca were connected to the water supply network. The vil- lages of Veljusa and Kosturino are not yet connected to the water supply network [15]. - uously.

In 2013, Ambarkova., et al. conducted an epidemiological study among 15 secondary school students from two high schools from the Strumica city and received an average DMFT index of 3.55 among these respondents [18]. This has prompted us to take this study in order to determine the prevalence of dental caries in 6-year-olds from the Southeast region, as well as determine the correlation Citation: Ambarkova Vesna. “The Correlation between the dmft/DMFT Index of 6-Year-Old Children and the Concentration of Fluorine in Drinking Water from the South-East Region of the Republic of Macedonia”.
