The most important problems of modern dentistry cover not only the early diagnosis but also prevention of dental caries, including the one based on the use of various hygienic products and therapeutic agents. Normally, the processes of re- and demineralization in the oral cavity are in a state of dynamic. However, in the presence of cariogenic factors, the balance is shifted towards demineralization. In the event of initial caries, enamel remineralization is possible only to a certain extent, and specifically, for a reversible degree of carious lesion. There was an idea about structural changes in polymer-based consumable dental materials including toothpastes. The purpose of the study is to increase the efficiency of dental caries prevention based on the activation of metabolic processes in dental hard tissues with the use of R.O.C.S. Active Calcium toothpastes (Russian-Swiss "DRC-Group" company) modified by an electromagnetic field. As a result of the experimental part of the study, certain changes in the properties of the R.O.C.S. Active Calcium toothpastes under the electromagnetic field influence including microstructural transformation of the toothpaste (an increase in the size of the polymer matrix particles and a decrease in the distance between them confirmed by the electron microscopy findings), confirmed by the transmission electron microscopy results. The investigations with the help of X-ray microanalysis made it possible to clarify the chemical composition of the surface layer of the tooth enamel, for the first time to reveal in detail the concentration of micro- and macroelements of organic and inorganic nature, to trace the changes occurring under controlled tooth cleaning with the R.O.C.S. Active Calcium toothpaste treated with an electromagnetic field. The obtained results promote the further studies of laws in change of physical and mechanical properties of treatment-and-prophylactic means under the electromagnetic field influence in respect of dental caries preventive maintenance efficiency increase.
现代牙科最重要的问题不仅包括早期诊断，还包括龋齿的预防，这其中包括基于使用各种卫生产品和治疗剂的预防方法。通常情况下，口腔中的再矿化和脱矿化过程处于动态平衡状态。然而，在存在致龋因素的情况下，平衡会向脱矿化方向偏移。在龋齿初期，牙釉质再矿化仅在一定程度上是可能的，具体而言，对于可逆程度的龋损才有可能。曾有关于包括牙膏在内的聚合物基牙科消耗材料结构变化的想法。本研究的目的是通过使用经电磁场改性的俄罗斯 - 瑞士“DRC - Group”公司生产的R.O.C.S.活性钙牙膏，激活牙齿硬组织中的代谢过程，从而提高龋齿预防的效率。作为研究实验部分的结果，R.O.C.S.活性钙牙膏在电磁场影响下其性能发生了某些变化，包括牙膏的微观结构转变（聚合物基质颗粒尺寸增大以及它们之间的距离减小，这一点通过电子显微镜观察结果得以证实），透射电子显微镜结果也证实了这一点。借助X射线微分析进行的研究使得明确牙釉质表层的化学成分成为可能，首次详细揭示了有机和无机性质的微量元素和常量元素的浓度，追踪了在使用经电磁场处理的R.O.C.S.活性钙牙膏进行受控牙齿清洁过程中所发生的变化。所获得的结果有助于进一步研究在电磁场影响下治疗和预防手段的物理和机械性能变化规律，以提高龋齿预防维护的效率。
