The study of molecular composition in biomimetic interface of biocomposite/dentin

Abstract

The aim of the study is the problem of formation of the biomimetic interface between the dental product and dentin of the human tooth as well as the investigations of molecular-chemical features in biointerface with the use of molecular multivariate IR-visualization. The data on synchrotron IR-mapping made enabled to differentiate the regions of sound dentin tissue and biomimetic transition layer and also to determine molecular groups responsible for the process of integration.

Synchrotron X-ray Studies of the Structural and Functional Hierarchies in Mineralised Human Dental Enamel: A State-of-the-Art Review

“…Molecular analysis using FTIR and attenuated total reflection (ATR)-FTIR is suitable for studying the interface of different materials, as well as to evaluate their interactions. This approach was utilised to study biomimetic composites, dental materials, dentine and enamel interface, and phosphate and amide groups (corresponding to mineral and organic components respectively [ 324 , 325 , 326 , 337 , 347 , 352 , 562 ], Figure 9 m), to develop hybrid interfaces. In another study, the distribution of organic and carbonate contents was determined from ancient and modern teeth [ 341 ].…”
