Relevance. There is currently an active introduction of information technologies in various spheres of human life, especially medicine. And dentistry is no exception, which undoubtedly increases dental care level. The article describes a computer program for the preclinical prediction of caries development risk in permanent teeth in children after the eruption. The program allows for identifying disease development risks allowing you to carry out preventive measures in advance. Purpose: Development of a simple and accessible computer system providing information support to dentists in dental caries risk identification and timely prescription of preventive measures.Material and methods. Obtaining and processing information on the clinical and laboratory parameters of caries-resistant children with mixed dentition was the first stage for creating a computer system. The statistical analysis detected the factors influencing the carious process development risks and determining critical values. A developer wrote a program, according to the requirement specifications, which simulates possible carious process development risks.Results. The received software allows for identifying caries development risks at the preclinical stage, scheduling checkup times and recommending duly caries preventive measures.Conclusion. Software program experimental implementation showed a high coincidence between the clinical picture and PC program approbation after a two-year observation of caries-resistant children with mixed dentition.

Резюме С целью изучения результатов лечения начального кариеса постоянных зубов у детей с компенсированным течением кариозного процесса с помощью реминерализующего геля было осмотрено 1682 школьника г. Омска в возрасте 7-12 лет. Взято под наблюдение 30 детей с компенсированным течением кариозного процесса, имеющих начальный кариес эмали. Группа разделена на две подгруппы: в первую подгруппу вошли дети, которым проводили санацию полости рта, обучение гигиене полости без применения лечебно-профилактических средств; во вторую подгруппу вошли дети, которым назначался кальций-фосфатсодержащий гель модели «Слюна» (авторское свидетельство № 1119693 от 22.06.1984 г.). Оценка результатов лечения проводилась комплексно на основе анализа клинико-лабораторных параметров гомеостаза полости рта. Установлено, что на фоне обучения рациональной гигиене полости рта и санации полости рта отмечается физиологическая реминерализация очага деминерализации эмали. Назначение реминерализующей терапии при лечении начального кариеса зубов еще более оптимизирует процесс реминерализации эмали зубов и снижает степень риска усугубления деминерализации эмали у каждого индивида. Ключевые слова: начальный кариес, компенсированная форма кариеса, деминерализация, реминерализация, гель модели «Слюна».

Subject. Oral fluid plays a crucial role in maintaining the physiological balance of the processes of remineralization and demineralization in tooth enamel, especially in childhood. The mineralization and demineralization of tooth enamel depend on the mineralizing potential of the oral fluid, which is associated with the concentration of calcium ions and phosphate ions in the oral fluid at a certain pH of the medium. Today, the description of the morphology of crystals is reduced mainly to a qualitative assessment. This is inconvenient due to subjectivity in data processing. The goal is to increase the accuracy and objectivity of diagnosing the level of mineralizing potential of the oral fluid by quantifying the type of saliva microcrystallization and expand the ability to diagnose the risk of developing and exacerbating the degree of activity of the carious process in a pediatric dentistry clinic. Methodology. The research material was human saliva, which was taken in the morning, on an empty stomach, before brushing your teeth in a sterile test tube with a tight-fitting lid. Results. The results of the studies revealed statistically significant differences in the periodicity parameters with respect to type III saliva microcrystallization (p <0.001), in which the mineralizing potential of the oral fluid is less favorable for the optimal level of ion exchange between the oral fluid and the tooth enamel surface during the maturation period of the child’s dental hard tissues. Suggested technique determining a periodicity parameter characterizing the quantitative difference in the types of saliva microcrystallization can be used To assess the level of mineralizing potential oral fluid. Conclusions. The study allows to increase the accuracy and objectivity of diagnosing the level of mineralizing potential of the oral fluid by quantifying the type of microcrystallization of saliva and expands the possibility of diagnosing the risk of developing and exacerbating the degree of activity of the carious process in the clinic of pediatric dentistry.

Background. Preventive measures that are implemented through the introduction of regional prevention programs have a massive focus and do not lead to a decrease in dental morbidity, because they are based on routine preventive measures without taking into account the individual characteristics of metabolic processes in the patient's oral cavity. All this confirms the need to abandon the mass approach when carrying out preventive measures, and requires the search for modern methods for predicting dental caries, based on predictive diagnostics of the risk of caries, which should be a key element of clinical examination of the pediatric population by a dentist. Purpose of the study: on the basis of a comprehensive clinical and laboratory approach with the use of mathematical analysis of the obtained data on homeostasis of the oral cavity, to establish predictors of the development of the carious process in children in order to determine the possibility of predicting dental caries during the period of mixed bite. Methodology. To achieve this goal, a comprehensive clinical and laboratory examination of metabolic processes in the oral cavity was carried out in 60 caries-resistant children during the period of mixed bite: from 7 to 12 years. Statistical analysis was performed using the STATISTICA 8.0 software. Results. According to the results of the study, strong relationships were revealed between individual clinical and laboratory indicators-predictors, an optimal set of predictors was established for constructing classification models for patients with different types of MCS, which is a prerequisite for the possibility of predicting the risk of caries development in children during the mixed bite period. Conclusions. An optimal set of predictors has been established for constructing classification models for patients with different types of ISS for creating computer programs aimed at preclinical diagnostics of the subclinical course of the carious process with access to prediction, which will allow planning individual primary preventive measures in children during the period of active formation of hard dental tissues.
