Aim: To assess the possible correlation of three known cariogenic factors with the prevalence of dental caries in adolescents living in countries with a similar industry and health care levels. Methods: Meta-analysis of the analytical dental epidemiology data among 12 - 15 - year-old children of Belarus, Kazakhstan and Russia. The EGOHID-2005 system was used in the intercountry research project with the authors participation. Every study group comprises of 100 and more subjects in all sites of the project, were oral health assessment and quiz were performed. The dental caries trends among 12-year-old children in countries studied were estimated from the epidemiological data published in 1960th-1980th. Results:During the last 35-45 years, the prevalence of dental caries in 12-year-old children has decreased from 3.5 to 2.4 DMFT in Belarus; has increased from 2.4 to 3.3 DMFT in Kazakhstan; has stabilized at level of 3.2 DMFT in Russia. The different trends of dental caries have coincided with different prevalence of behavioral risk factors. The most important factor reducing caries were fluoridated toothpastes; the most cariogenic factor were sweet drinks; the frequency of toothbrushing was not correlating with dental caries intensity.Conclusion: This study has proved the different trends of dental caries in children of Belarus, Kazakhstan and Russiawhichappears depend on different prevalence of behavioral risk factors among school children and operating community preventing programs.

The clinical assessment of the medical efficiency of the R.O.C.S., low fluoride (500 ppm F-), toothpaste was performed in 2-year school - based toothbrushing program involving 180 7-year-old children. After 8 years of monitoring the reduction of DMFT was by 18% as compared to the control group of children of the same age. The results of this study suggest that low fluoride toothpastes were effective in prevention of dental caries in schoolchildren even in the long-term period.

The purpose of this review is to analyze modern methods of treatment and prevention of oral mucositis in children. Attention is paid to the importance of oral cavity sanitation in children with oncological diseases. The drugs used in the treatment of oral mucositis are considered. The effectiveness of drug treatment and light therapy with laser therapy is compared. A study of the mechanism of action of laser therapy in the treatment of oral mucositis is presented.

24 children were examined and treated. 24 permanent teeth with incomplete mineralization of hard tissue were treated using method of prophylaxis filling. For filling we used classic glass ionomer cement MNN. This technique saved clinical effectiveness during 18-24 months after treatment. Аfter this period the final stage of deferred sandwich technique is recommended.

The aim of this work was to study the effectiveness of a minimally invasive method of caries treatment of permanent teeth, with unformed roots. A study was made through 90 children aged 7-13 years of school No 42 in Tashkent. The subjects are divided into 2 groups. In 1 group, treatment of dental caries with the example of 1 permanent molar (1PM) was carried out by minimally invasive method, followed by filling of the «Argion molar AC» (102 fillings). In the second, caries treatment (1PM) was carried out using the traditional method of Black preparation and sealing of carious cavity with silicophosphate cement «Belotsin» (129 seals). Treatment with a minimally invasive method was carried out step by step under the control of the caries of the detector with a 0.5% solution of fuchsin. In this case, only the pathologically altered upper layers of dentine were stained, which was carefully removed to a dense light layer. Necrotomy was repeated several times until all the colored areas were removed. A comparative study revealed a significant effectiveness of the minimally invasive method over the traditional one. So, with the traditional method of treatment, after 6 months, they were noted after filling up the three criteria studied. In the first place, the development of secondary caries is 28,7 ± 3,1%, in contrast to 4,5 ± 1,6%, on the second - the violation of the marginal fit of the seal 22,3 ± 2,7% in group 1 - 5,3 ± 1,5% and the violation of the anatomical form of the seal 12,3 ± 1,8, vs. 3,1 ± 1,2%. Thus, a comparative assessment of the methods of treatment and sealing in the treatment of caries 1PM during the formation of the root of the tooth and the incompleteness of the mineralization of hard tissues of the teeth showed a sufficiently high clinical efficiency of the minimally invasive method of preparation with the use of SIC «Argion Molar AC» in comparison with the traditional method and the use of silicophosphate cement «Belotsin».

The article is devoted to questions of hypomineralized primary second molars and molar incisor hypomineralization. The recommended treatment options are given depending on the severity of the disease and the symptoms presented by the patient. As a method of temporary treatment for such cases, it is recommended to install a preformed metal crown. Features of the technique for fixing the preformed metal crown on the tooth without preparation are discussed using the so-called "Hall technique". Several clinical cases are presented.

Article contains results of 3 year study of 2 groups of children age 3-9, whose molars were restored using different techniques after treatment of chronic fibrous pulpitis. In first group 128 temporary molars were restored using sealing materials (glass ionomer cements, compomers), In second group 106 temporary molars were restored using standard metal crowns (3М ESPE USA). After teeth extraction because of inflammation or natural loss clinical efficiency of different restoration methods for coronal part was evaluated using clinical and radiographic methods and also electron microscopy data. Caries rate among children age 3-7 during 3 years was detected in both groups. According to clinical and radiographic observation, percentage of stable teeth, percentage of teeth that need to be retreated, and percentage of extracted teeth due to periodontal pathology was identified in each group. In first group among 128 teeth, which initially were restored using sealing materials, during 3 year evaluation period retreatment because of poor stability of restoration was performed 201 times (157%), 47 teeth were extracted (37%). In second group among 106 teeth restored with standard crowns during 3 year evaluation period retreatment was performed 33 times (31%) and 8 teeth were extracted (7,5%). According to scanning electron microscopy all specimens of teeth that were subjected to premature loss due to periodontal infection demonstrated restoration fitting deficiency. Temporary molars restored with standard crowns and lost due to second dentition demonstrated good crown and cement fitting. Caries rate evaluation among group of children 3-7 years show high caries increment (1,44) among patients with seals compared to patients with standard crowns (0,66). We recommend including temporary molar restoration using standard metal crowns into routine protocols.

The paper presents the materials of a prospective clinical study of 170 children aged 4 to 6 years with the violation of nasal breathing. We studied the life history of children check dental status; evaluation of intensity of caries process; the risk factors and the presence of dentofacial anomalies, determination of the hygienic state of the oral cavity in children. Comparing the obtained data, we propose an algorithm for cooperation of dentist and doctors of other specialties, with the aim of providing preventive and curative care to children with impaired nasal breathing, as well as recommended circuits prescribing calcium, vitamin D and fluorides depending on the age of the child.

In 91 children with diabetes mellitus of the first type in the blood serum and oral fluid at various stages of disease compensation using index indicators, the periodontological status, the level of matrix metalloproteinases (MMP-1, MMP-2, MMP-8, MMP-9), their tissue Inhibitors (TIMP-1, TIMP-2), and the relationship between the expression of inflammation factors and the clinical picture of periodontal disease. Results are compared with similar parameters of 38 children without endocrine pathology. The obtained results indicate that in children with compensated type 1 diabetes mellitus, the processes of synthesis of matrix metalloproteinases and their tissue inhibitors are balanced in the presence of reversible inflammatory changes in periodontal tissues. With the decompensated form of type 1 diabetes mellitus, there is an imbalance between the synthesis of matrix metalloproteinases and their tissue inhibitors, which provokes disturbances in remodeling processes and the structural organization of the extracellular matrix in periodontal tissues of irreversible nature.

The subject of this article presents is to examine the influence of toothpastes with various foaming components on the indices of nonspecific immunity of the oral cavity (Yasinovsky’s test, Kavetsky’s test). The study shows that the sodium lauryl sulfate has a negative effect of on components of nonspecific protection of the oral cavity was revealed. Differences in the cleaning ability of toothpastes are not revealed.
