The right selection of home hygiene products and their long-term use is an urgent issue in modern dentistry. For research of the correct combination of hardness of toothbrush and abrasiveness of toothpaste was crated a model of the enamel. In the article the following goals were solved: the microstructure and microhardness of dental hard tissues have been investigated; was studied effect of changes of the roughness of enamel surface in imitation of 1 year brushing of a hard toothbrush and paste of medium abrasivity (RDA 60); the material for creating of the tooth enamel was determined. The study of the enamel microstructure showed that an oriented structure is characteristic of the enamel. Usage a hard brush in combination with a paste of medium abrasivity (RDA 60), the optimal time for this combination can be recommended for more than a year. A further direction of investigation is associated with the assessment of the suitability of the resulting model of tooth enamel in study of changes in the enamel surface due to use of a hard brush with a paste of varying degrees of abrasivity.
