Currently, a large number of methods for caries prevention and treatment have been developed and implemented. However, the problems with the extension and development of this process are redoubling every year. Against this background, it is urgent to develop methods that prevent the development of this pathology. To date, long-term results of treatment of caries in the staining stage by infiltration have been obtained. This technique makes it possible to stop the development of the carious process at the spot stage by impregnating pathologically altered tissues with a methacrylate-based drug, which stabilizes the development of caries and creates conditions for the restoration of damaged areas. But the question of using Icon for the treatment of focal demineralization of enamel in the defect stage is still relevant. The purpose of this research is to study the effectiveness of enamel focal demineralization treatment based on the application of the infiltration method in combination with various restoration technologies. The research was conducted on 30 selected teeth, which were removed for various reasons and had not been previously treated endodontically. After mechanical cleaning of the tooth surface from the plaque on the vestibular surface of all samples was created artificial demineralization of enamel in the defect stage. A point defect was created on the vestibular surface of all samples within the demineralization zone using spherical boron. Then the infiltration with Icon (DMG) was carried out according to the manufacturer's instructions, and the teeth were divided into 6 groups of 5 samples each. The study revealed a dependence between the choice of filling material and the size of the prepared cavity. In cases in which the cavity is extensive, using composite materials with traditional consistency and compomers is preferable. If the cavity is small, then fluid materials (composites or compomers) can be used to restore the defect because these materials spread evenly throughout the tooth cavity due to their liquid consistency.On the experimental model, it was possible to establish the effectiveness of the combination of the infiltration method with Icon preparation and restoration with light curing filling materials.
