Dentin Hybridization – Modern Based Therapy of Restoration of Compromised Dental Structure

Abstract :

The aim of this study was to highlight the structural characteristics of the dentin hyid layer generated in the case of two different adhesive systems. Methodology: On 25 extracted teeth, deep cavities were produced and two types of adhesive systems were applied: an adhesive system applied consecutively with dentin demineralization and a self–etching adhesive system applied directly to mineralized dentin. Results: In the control group, SEM examination highlighted the presence of free dentinal tubules and smear surface layer. In the study groups, SEM examination revealed the absence of the smear layer and the forming of a hyid layer. Conclusions: Conventional adhesive systems applied consecutively with the self–etching acid have the capacity to produce a hyid layer of high quality. Self–etch adhesive systems can achieve a strong adhesive bond by dissolving and including the smear layer in its composition.
