Aim. To study the content of Ca, P, F and I in enamel and dentin composition of deciduous teeth, which are formed in fluoride and iodide deficiency, and its dynamics on the background of the 3-year consumption of fluorinated and iodized salt.Methods. The mineral composition of the deciduous teeth enamel and dentin of 6-12 years old children, born and living in conditions of biogeochemical deficiency of fluoride (0.02-0.08 ppm F in water) and iodide (0.033-0.005 ppm I in water) before and after consumption of fluorinated and iodized salt containing sodium fluoride 300±50 ppm F and potassium iodate 40±10 ppm I was studied. The first phase of the study was conducted before inclusion of fluorinated-iodized salt in the diet of schoolchildren. Using X-ray microanalysis, macro- and microelements of 47 intact deciduous teeth were studied. The contents of the four elements (Ca, P, F, and I) in three layers of enamel (the surface layer, intermediate layer, at the enamel-dentin border) and in three layers of the dentine (the layer at the enamel-dentin border, a middle layer, circumpulpal layer). The second phase of a study on the mineral composition of the enamel and dentin was conducted 3 years after the beginning of fluorinated and iodized salt consumption. 51 deciduous intact tooth were investigated.Results. 3-year consumption of table salt with the addition of sodium fluoride and potassium iodate has led to a significant increase in calcium, phosphorus in the enamel of the all teeth groups. The highest content of fluorine was registered in the molars where the level of fluorine increased by 2.08 times from baseline. The fluorine level in canines increased by 1.76 times from baseline, in incisors - by 1.69 times. The iodine content in the enamel increased approximately 2-fold (incisors - 1.77 times, canines - 1.89 times, molars - 1.85 times), in the dentin, depending on the teeth groups, increase in the studied parameter was by 3.12-3.51 times.Conclusion. 3-year consumption of fluorinated and iodized salt containing sodium fluoride 300±50 ppm F and potassium iodate 40±10 ppm I stimulates increasing the content of Ca, P, F and I in the enamel and the dentin of deciduous teeth formed in fluoride and iodide deficiency.
Aim. Evaluation of dental diseases prevalence in professional athletes engaged in power sports and of the influence of biologically neutral products based on propolis on the level of their dental health. Methods. The examination of organs and tissues of the oral cavity of professional athletes engaged for a long time in power sports was carried out. With the use of the developed specialized questionnaire dental status of the athletes was determined. Based on the analysis of the results of clinical and laboratory studies anti-inflammatory and anti-bacterial effectiveness of products based on propolis were evaluated. Results. The results of the survey showed that not all athletes are informed about the possibility of aggravation of pathological processes in soft and hard tissues of oral cavity during active training, mainly, in power sports. Lack of awareness of surveyed athletes about the need for timely individual oral hygiene procedures and regular dentist visits was revealed, especially during intense training before and after competitions. On evaluation of dental status of professional combat athletes high prevalence and intensity of inflammatory periodontal disease and caries were found. High anti-inflammatory efficiency of the product «Pomegranate Balm» for correction of dental status of professional athletes was proven. Conclusion. High incidence of inflammatory periodontal diseases of mild to moderate severity was revealed in athletes during prolonged and intense physical training; efficacy of biologically neutral products based on propolis was established.
Clinical evaluation of the quality of restorative materials carried out taking into account indicators hygiene index, some criteria: absence of side effects on the tissue surrounding the tooth. While taking into account the almost constant contact with the seal gums determined the importance of assessing the extent of its impact on their functional status. Have been revealed the direct dependence of the state of oral hygiene, pathological changes in the soft tissues and the seal quality. One of the objectives of the study was to determine the quality of the restoration carried out in the cervical area, depending on the depth of gingival sulcus in the presence of inflammation in periodontal tissues. The maximum depth of the gingival pocket, which is permissible under the direct defect filling, was 3 mm clinical studies found a direct relationship between the restoration qualities and cavity extent below the gingival margin. Maximum positive results on the quality of sealing recorded in the first group, an intact periodontal pocket depth. Analysis of the results of clinical studies of the oral cavity examined patients before and after treatment and preventive measures are revealed a number of features. Carrying out preventive and curative action using both traditional means and biologically neutral drugs has reduced the value of the index OHI-S GI and achieve significant improvements in oral hygiene status in patients in all stages of clinical trials.
