Relevance. Underestimating the importance of economic analysis is the barrier to the implementation of cariesprevention programs.The aim is to study with use of mathematic modeling method the clinical and economic effectiveness of dental caries prevention programs provided for schoolchildren.Materials and methods. The method of mathematic modeling was used to evaluate the clinical and economic efficiency of the caries prevention programs (educational, fissure sealing, fluoride varnish). The cost of prevention program implementation and the expenses for caries treatment without prevention were calculated according to the rate of Volgograd territorial mandatory medical insurance Fund for 2018 year. The differences between the caries prevention program’s cost and the expenses needed for the treatment of “prevented caries” were considered as saving.Results. It was revealed that the Educational Dental Program for the first grade schoolchildren has short duration (2 years) of clinical-economic efficiency. The Continuous Educational Dental Program applied for 6 years by dental hygienists or dentists led to saving (per 100 children) of 99.5-115.0 or 84.0-99.6 thousand roubles respectively. The economic effect of The First Permanent Molar Fissure Sealing Program was revealed after 2 years only when The Program was implemented by dental hygienists. After 6 years of working with this Program the saving were 181.3 or 146.2 thousand roubles per 100 children depending on who implemented the Program, dental hygienists or dentists. The cost of Fluoride Varnish Program implementation was higher than the treatment of “prevented caries”. However, the number of “prevented caries” after fluoride varnish application is higher than after the implementation of the Educational Dental Programs. Moreover, fluoride varnish, in contrast to fissure sealing, prevents caries of smooth surfaces of permanent teeth. Conclusions. The method of mathematic modeling can be used for the development of the caries prevention programs in various regions considering the availability of personnel and financial resources, and for evaluation of the clinical and economic effectiveness of preventive programs implementation.

Background: DM mellitus (DM) leads to worsening periodontal diseases, and in turn the inflammatory diseases of maxillofacial region adversely affect the glycemic control and exacerbate the severity of DM, thereby engendering a vicious cycle that compromises the DM management in patients. Taking account of the bidirectional relationship between DM and periodontal disease, interdisciplinary examination of patients with both DM and periodontal diseases is warranted to improve the health outcomes in patients. Aims: This study aims to evaluate the perceptions of dentists and endocrinologists on the interdisciplinary cooperation for identification and management of patients with DM. Materials and methods: Studying patients knowledge about DM and their compliance in providing endocrinological recommendations, dental screening survey to identify DM risk and signs The research was done in 2015-2016 years using clinical survey (dental status survey), statistical analysis. 432 patients from different dental organizations and 433 doctors (371 dentists and 62 endocrinologists) took part in the research. The research was approved by Regional research ethics committee. The written informed consent was taken from each participant. Results: There was insufficient interdisciplinary collaboration for identification and management of patients with diabetes, and lack of motivation among dental patients to endocrinological survey. Hence, it is important to incorporate definitive screening for risk of DM for patients with inflammatory periodontal disease and include dentists in consultation for patients with DM. The feasibility of statutory determination of collaboration between specialists in identification and management of patients with DM was found, dental lectures are necessary in DM school. Conclusions: Our findings suggest the necessity of including dentists in the standard of medical management of patients with DM and incorporating DM screening by a questionnaire upon dental examination.

The oral microbiota plays an important role in maintaining dental and systemic health. The interaction between the oral and gut microbiota highlights the bidirectional connection between oral health and systemic health, where disturbances in one micro-ecosystem can spill over into the other. An imbalance leading to oral dysbiosis can accelerate a range of oral diseases, such as caries, gingivitis, periodontitis, halitosis, and oral candidiasis and also have profound impacts on overall health, including gastrointestinal disorders, cardiovascular and neurological diseases, and endocrine imbalances. Modern research emphasizes the importance of maintaining a healthy oral microbiota through regular and high-quality hygiene. Using parodontax toothpastes containing a high concentration of sodium bicarbonate and sodium fluoride can promote oral health and reduce the risk of systemic diseases. When using removable dentures, it is necessary to use specialized Corega products for fixation and cleaning.

Relevance. In the actual dentistry a special place takes opportune diagnosis of early stages of dental caries and effective non-surgical treatment. In the recent times new approaches, technologies and methods for diagnosing focal demineralization of tooth enamel have been developed, among which the laser fluorescence method is widely used. Purpose. To study the results of local enamel demineralization treatment with the caries infiltration method according to laser fluorescence value. Materials and methods. The method of caries infiltration was applied in 99 permanent teeth with local enamel demineralization in 15 children aged 10-16 years. Laser fluorescence method was used for enamel demineralization assessment before and immediately after the treatment, after 6, 12 and 18 months. Three study groups were formed according to laser fluorescence value before the treatment: the first one – values 14-20 (initial enamel demineralization), the second one – values 21-29 (deep enamel demineralization), the third one – values ≥ 30 (enamel and dentine demineralization). Proportions (%), mean-values and standard errors (M±m) were calculated, significance (p) of differences was assessed according to Students’ criteria (t) at p < 0.05. Results. During 18 months after caries infiltration caries cavities forming were not revealed. The mean-values of laser fluorescence were in the first group before the treatment 17.38 ± 0.27, after the treatment 5.00±0.82, after 18 months – 4.82 ± 0.79; in the second group 25.42 ± 0.38, 15.25 ± 0.78 and 13.96 ± 0.75, in the third group 33.08 ± 0.69, 22.54 ± 1.39 and 20.77 ± 1.44 respectively. The differences between the values before and after the treatment were significant statistically (p < 0,001) in all groups. After 18 months the laser fluorescence values corresponding to healthy enamel were revealed in 94.1% cases in the first group, in 50.0% cases in the second group, and in 7.7% cases in the third group.Conclusions. Local enamel demineralization treatment of permanent teeth in children with the caries infiltration method prevented caries cavity forming. Monitoring laser fluorescence values revealed that the results of the treatment with the caries infiltration method depended on the depth of dental hard tissue demineralization.
