In modern maxillofacial surgery, the technique and mechanism of compression-distraction osteogenesis are still relevant as an alternative method of obtaining bone tissue in complex clinical cases. All types of compression-distraction devices used in practice have only a mechanical drive, i.e., fragments of bone tissue are separated fractionally in such devices, creating uneven tension in the newly formed regenerate, which leads to its incomplete ossification. We have developed, tested on a stand and tested in an animal experiment a distraction appliance operating on the principle of continuous separation of bone fragments, having a piston-type motor, activation of which occurs during an electrochemical reaction triggered and controlled by software with a feedback kit.Material and methods. The stages of our research were as follows: development of devices and electronics, bench tests, creation of clinical models of an automated continuous distraction device; clinical trials of devices, their placement in the experiment animals (dogs), testing of electronic continuous distraction devices at various rates (1 mm, 2 mm, 3 mm per day); morphological and clinical and radiographic evaluation of the bone regenerates, and development of clinical recommendations for the device application and distraction rates.Results. The received data based on the available clinical and morphological-radiographic picture between the bone fragments distracted by the device prove the possibility of regenerate formation during continuous distraction at various rates, when constant atraumatic stretching of the regenerate is maintained, without its transition to a fractional deformation similar to a pre-plastic one. At the same time, the analysis of morphological studies showed the best histomorphological regenerate maturity obtained by continuous distraction at a rate of 2 mm. per day.Conclusion. We can recommend the introduction of the automated continuous distraction device created by our experienced group into practical medicine at a distraction rate of 2 mm. per day.","PeriodicalId":196403,"journal":{"name":"Pediatric dentistry and dental prophylaxis","volume":"08 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127216577","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For several decades, they have added bacteria called probiotics to some foods for their positive effects on human health. In dental practice, probiotics may help fight caries and inflammatory periodontal diseases. Dentists are interested in probiotics because of the latter’s ability to adhere to and colonize various oral tissues.Purpose. To evaluate the clinical effectiveness of S. salivarius M18 probiotic in preschool children.Material and methods. The study formed 2 groups (45 children in each) of children aged 3 to 6 years with multiple dental caries who underwent dental treatment and 4-fold fluoride varnish application. The main group took 2 courses of S. salivarius M18 probiotic lozenges (the 1st course from February 16 to May 16, 2021, and the 2nd course from October 26, 2021, to January 26, 2022). The children of the comparison group did not use the probiotic. We evaluated the Hygiene Index by Fedorov-Volodkina, dmf(t) rate, ICDAS-II index, and PMA index in children of both groups at the baseline and after 3, 6 and 12 months. Additionally, both groups kept food diaries. The statistical data processing was performed variance analysis of using the Friedman test (significant differences were at p ≤ 0.05).Results. The year of observation in preschool children showed that two 3-month courses of an S. salivarius M18 probiotic intake led to a signifcant improvement in the hygiene index by 2.2 times, 2.3-fold stabilization of initial caries according to the ICDAS II index, caries decrease by 81%, gingivitis prevalence reduction (PMA index decrease by 72.9%).Conclusion. The study results confirm the effectiveness of S. salivarius M18 probiotic in preschoolers with caries as a means of dental status correction and stabilization.","PeriodicalId":196403,"journal":{"name":"Pediatric dentistry and dental prophylaxis","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127349929","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The lack of anatomical differentiation between the oral cavity and the nasal cavity in children with congenital cleft palate leads to the deterioration of saliva characteristics affecting dental and periodontal disease progression. The oral fluid immunological profile may provide information about the nature of the inflammatory processes and changes in the reaction to the ongoing therapy.Material and methods. The article presents the results of the oral fluid enzyme immunoassay in 109 children aged 6-12 years with congenital cleft palate and a postoperative defect and in 50 practically healthy children of the same age. The study determined the levels of pro-inflammatory (IL-1β, IL-6, TNF-α) and anti-inflammatory (IL-4, IL-10) cytokines and secretory immunoglobulin sIgA in the oral fluid by enzyme-linked immunosorbent assay.Results. The study of children aged 6-12 years with congenital cleft palate and a postoperative defect revealed hyperstimulation of oral fluid pro-inflammatory (IL-1β, IL-6, TNF-α) and anti-inflammatory (IL-4, IL-10) cytokines and a decrease in secretory immunoglobulin sIgA mean level.Conclusion. The oral fluid immunological complexes imbalance in children with congenital cleft palate and a postoperative residual defect is a progressive factor for the development and chronicity of oral inflammatory diseases.The received data evidence the local inflammatory process and a decrease in the oral fluid local protective factors, which one must consider to develop methods for improving the condition of organs and tissues of the oral cavity in children with congenital cleft palate during preparation for surgery to eliminate the residual defect.","PeriodicalId":196403,"journal":{"name":"Pediatric dentistry and dental prophylaxis","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114288412","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

High dental disease incidence in children is still a relevant problem of public health care in Russia. Regional or national oral disease incidence rates may decrease via the introduction of state or Regional prevention programs. School dentistry is crucial in the pediatric dental care system. Different socio-economic, climatic and geographical conditions of various Regions of the Russian Federation affect the possibilities of preventive program implementation in the child population. Purpose – to evaluate the implementation of dental disease prevention programs in pediatric dental services in several constituent entities of the Russian Federation.Materials and methods. In 2020, employees of Moscow State University of Medicine and Dentistry visited the Regions of the Russian Federation 39 times within the implementation of the national project \"Healthcare\" and national medical centre activities. In these Regions, the study examined the following parameters: availability of a Regional dental disease prevention program, the functioning of dental offices in educational institutions, dental checkup coverage rate in children.Results. The study revealed that most Regions have school-based dental offices in the pediatric dental service. School-based dental offices provide treatment and prevention procedures. The analysis showed that all studied constituent entities carry out dental checkups. However, the dental checkup coverage rate in children varies greatly.Conclusions. A small number of Regions (23.07%) have approved and are implementing a Regional prevention program, several entities (20.51%) are validating similar programs. And the majority of the studied constituent entities (56.41%) don’t have Regional prevention programs.","PeriodicalId":196403,"journal":{"name":"Pediatric dentistry and dental prophylaxis","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122660547","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
