THE QUALITY OF DRINKING WATER AS A FACTOR IN THE FORMATION OF DENTAL PATHOLOGY OF THE HARD TISSUES OF THE TEETH IN CHILDREN.

OBJECTIVE: The aim: A study of the impact of drinking water quality on the state of dental health in schoolchildren who permanently live in areas of biogeochemical deficiency of fluorine and iodine. PATIENTS AND METHODS: Material and methods: The composition of the drinking water of the city of Uzhhorod and the city of Rakhiv has been investigated. The prevalence and intensity of dental caries in children is determined, drinking water is taken in accordance with Uzhhorod and Rakhiv. RESULTS: Results: The regional features of the composition of drinking water of the mountain Rakhivsky district of the Transcarpathian region are the high variety of combinations of mineral components and the frequent excess of the normative content of dry residue components, namely nitrates, sulfates, chlorides, magnesium and calcium.Water oxidation, total stiffness and total alkalinity were significantly different. The established drinking water quality indicators have a direct dependence on the prevalence and intensity of dental caries in children, that is, a significant increase in the number of carious temporary, carious and distant permanent teeth and a decrease in filled temporary and permanent teeth (p < 0. 05) were diagnosed. CONCLUSION: Conclusions: One of the most pressing problems in water hygiene is the urgent need to review and improve regulations, State sanitary regulations, standards and other regulations in the field of drinking water, including through the development of regional drinking water quality standards.

Statistical analysis of the impact of clusters on caries prevalence and intensity in children aged 6-7 with different somatic health statuses.

OBJECTIVE: The aim: Determining the influence of cluster factors on the emergence and progression of caries in first- and second-grade children is appropriate in terms of determining the most significant ones. PATIENTS AND METHODS: Materials and methods: The dental status of 73 children, residents of Uzhhorod, who study in the first grades of secondary schools, has been assessed, three groups have been singled (the control group 26 healthy children). The indices of essential micro- and macronutrients in the hair, saliva, serum and urine, as well as anxiety level have been determined and the statistical analysis has been performed. RESULTS: Results: Decreased magnesium and calcium content in hair, serum, urine and mouth fluid, iodine is absent. Children of the third group have high levels of anxiety (80%), high rates of caries (14,8) and significantly reduced levels of magnesium relative to normal. CONCLUSION: Conclusions: In the patients of the main groups, a direct correlation was found between the presence of somatic pathology and the level of anxiety. In 80% of children of the third group (CSPS≥3) the level of anxiety is high In the main group patients, a direct correlation was found between the presence of somatic pathology, the level of anxiety, and the decrease in magnesium; The intensity of caries only interacts with a high level of anxiety (1.00), that is, in children who are in constant stress, the intensity of caries increases.

Clinical and Laboratory Grounds for the Rational Selection of Filling Material for the Restoration of Deciduous Teeth

Objective: To compare the use of two different restorative materials placed in deciduous teeth. Material and Methods: Clinical observations were formed in the number of 58 patients aged 3 to 12 years; 23 - with deciduous dentition, 35 with mixed dentition. The total number of teeth was 266. The Index of destruction of the occlusal surface of the teeth (IROPZ) and the following materials were used: Ionofil Molar® (VOCO) and Twinky Star® (VOCO). Microphotographs of the sections selected for illustration were performed using a Biorex-3 VM-500T microscope with a digital DCM- 900 attached photo element using for interpretation of the results adapted data research software. The Spearman correlation coefficient [r] was used to examine the relationship between the parameters evaluated. The level of significance was set at 5%. Results: The Twinky Star® compomer has been found to be optimal for restoring the teeth with an IROPZ of less than 0.55, pH levels of <6.2 and any values of the degree of acidity of the enamel [r = 0.89]. Ionofil Molar® showed to be a material of choice with high and average degrees of acidity of the enamel [r = 0.65]. Conclusion: Choice and usage of different types of restorative materials depend on the period of bite, the condition of root formation, group membership of the teeth, depth and topography of the carious, the level of the pH of the saliva, the degree of acid resistance enamels and areas of destruction of the occlusive surface of the tooth.
