Abstract
A study is conducted to obtain spectral data on the penetration of the chemically cured adhesive “Tokuyama Universal Bond II” into dentin using various techniques. An external view of the used spectrophotometer is shown, an optical diagram of the instrument is presented, and the technical characteristics of the device are formulated. Samples for research, prepared using various methods, are depicted. The spectral dependences of the absorption coefficient are obtained in the zone of the boundaries of fixation of composite inlays with dentin and the border areas of the specimen-sections when using the Tokuyama Universal Bond II adhesive according to the protocol described in the manufacturer's instructions: when applying “Tokuyama Universal Bond II” with an additional 10-second exposure on the dentin before swelling begins; by rubbing “Tokuyama Universal Bond II” into the dentin surface for 10 seconds.
