Summary
A study aimed at obtaining tomographic data on the penetration of the chemical curing adhesive into the dentin when using different bond application techniques was carried out. High-quality aesthetics, durability, functionality and maximum preservation of hard dental tissues are the result of new adhesive preparation and improvement of the physico-chemical and optical properties of composites, therefore, the study of the optical properties of composites is relevant and promising. The paper presents the appearance of the spectrophotometer, an optical scheme is given and the technical characteristics of the device are given. Samples for studies made in various techniques are presented, and the measurement channel of the device is also shown, where samples were installed to measure the boundaries of the interaction of dental adhesive and dentin in depth. The spectral dependences of the absorption coefficient in the zone of the fixation boundaries of composite tabs with dentin and the boundary areas of the samples are obtained when using the adhesive according to the protocol described in the instructions; when applying with an additional 10-second exposure on the dentine before inflating; when rubbing of the adhesive into the dentine surface for 10 seconds before inflating. The data of the bond penetration into the dentin with usual techniques was revealed.

Keywords: spectrophotometer, absorption coefficient, composite, composite tab, chemical curing adhesive, universal adhesive, hybrid layer depth.
