“…Вопросы возникновения и развития кариеса, а также разработки информационно-измерительных систем (ИИС) для его диагностики представляют собой важную и актуальную задачу [1,2]. Наиболее перспективным методом для диагностики кариеса является электрометрический, заключающийся в измерении электропроводности твердых тканей зуба (ТТЗ) [3,4].…”

The article deals with the development of a medical device for high-precision measurement and automatic diagnosis of dental caries stage. The analysis of the composition and characteristics of tooth hard tissues, being the cause of caries and its development, is given. It has been established that the main cause of the carious process is the attack of acid-forming bacteria on tooth enamel. It is shown that the most promising method for caries diagnosis is the electrometric method, which consists in measuring electrical conductivity of the tooth hard tissue electrolyte. Conventional devices for the electrometric method implementation are described, using the direct current through the biological tissue of the tooth, but not taking into account the electrochemical features of the current flow. An electrochemical interpretation of the current flow through biological tissues and two electrodes with a polarity switch of these electrodes was performed, which makes it possible to exclude the effect of polarization of biological tissue and electrodes both for teeth in vivo and in vitro. An equivalent diagram of the current flow through the biological tissue is given, which value can reveal the stage of the carious process: intact enamel, pre-carious state, initial, superficial, medium and deep caries. The use of two current-carrying electrodes for measuring the electrical conductivity of biological tissues is considered: an active electrode made of stainless steel using a 10% solution of CaCl2 and a passive electrode also made of stainless steel and using an electrolyte of the biological tissue of a tooth (simulated by a 0.9% solution of NaCl). A comparative assessment of the tooth biological tissue electrolyte electrical conductivity and electrical conductivity of the active and passive electrode electrolytes was performed to assess the error of the electrometric method. A high-precision intelligent electrometric device (protected by a patent for an invention) has been developed, which allows automatic carious process stage determination by the value of the tooth biological tissue electrical conductivity; the operation of this device is described.

“…Самым распространенным и доступным средством гигиены является зубная щетка, которая позволяет удалять микробную биопленку с поверхности зубов [7]. На эффективность гигиены полости рта влияют конструкционные особенности щетки, качество, жесткость и степень износа щетины, а также целый ряд других факторов: мануальные навыки человека, регулярность, продолжительность и техника чистки [1,2,3,6,11].…”

The aim of the work is to conduct a clinical assessment of the effectiveness of toothbrushes of various types in children aged 6-11 years by dynamic monitoring of the condition of hard tissues of teeth, periodontal and hygienic status. Materials and methods: a parallel, randomized, open clinical trial was conducted aimed at evaluating the effectiveness of three different toothbrushes (two manual ones with different working parts and an electric one with the technology of reciprocating and pulsating movements) in children aged 6-11 years. The study involved 60 children aged 6-8 years and 60 children aged 9-11 years. In each age category, 3 groups of 20 people were randomly formed, who received toothbrushes of different types: groups I and IV - manual brush "Oral-B Junior" ("Procter & Gamble", Ireland), groups II and V - manual brush "ROCS Junior" (LLC "VDS-Stupino", Russia), groups III and VI - electric brush "Oral-B Pro 400 Junior Sensi Ultrathin". Dental examination included determination of KPUz+kpz indices, PI (Turesky S., 1970) and PMA (Parma S., 1960). After the examination, the children were taught the standard method of brushing their teeth. Repeated examinations were carried out after 1, 2 and 3 months. To compare the indicators of one group in dynamics, the Wilcoxon criterion was used, and the Mann-Whitney test was used to identify differences between groups. Results. The values of the KPUz+KPZ indices did not change in any of the groups during the study. In all groups, there was a significant decrease in PI after 1, 2 and 3 months from the start of the study (Wilcoxon criterion, p<0.05). The greatest reduction in the plaque index was observed when using an electric brush (significant differences with the groups where manual brushes were used, Mann-Whitney criterion, p<0.05). Of manual toothbrushes, the Oral-B Junior brush (soft, bowl-shaped brush field, CrissCross bristles, power protrusion) turned out to be more effective. Along with a decrease in the plaque index in all groups, there was a significant decrease in the PMA index (Wilcoxon criterion, p<0.001 compared to the baseline level). The achieved effect was maintained in terms of 2 and 3 months. from the beginning of the study, there was no significant difference between the groups (p>0.05). Conclusion: all toothbrushes were effective in controlling the supra-gingival plaque (visible biofilm), the highest effect was observed in groups of children who used an electric toothbrush.
