Enhancement performance of application mussel-biomimetic adhesive primer for dentin adhesives

Abstract

In this study, a bioinspired adhesive primer monomer was prepared and evaluated for durable adhesion between dentin and composite resins.

To the Question on the Use of Multivariate Analysis and 2D Visualisation of Synchrotron ATR-FTIR Chemical Imaging Spectral Data in the Diagnostics of Biomimetic Sound Dentin/Dental Composite Interface

“…The existing strategies of hybrid layer formation [ 4 , 5 ] are gradually improved. As concerning biomimetic similarity [ 4 ], these concepts are based on the new approaches and achievements in nanotechnologies [ 6 , 7 ]. Materials and bonding systems applied in dentistry nowadays have different compositions and are fabricated by different technologies, while some of them involve nanomaterials that are used to get the best reconstruction of the formation of the biogenic tissues [ 8 ].…”

“…Materials and bonding systems applied in dentistry nowadays have different compositions and are fabricated by different technologies, while some of them involve nanomaterials that are used to get the best reconstruction of the formation of the biogenic tissues [ 8 ]. There is an assumption that the qualitative bio-interface between synthetic material and natural hard tissue can be realised based on biomimetic strategy supposing the formation of the intermediate layer with the use of nanocrystalline carbonate-substituted hydroxyapatite (nano-c-HAp) and several polar amino acids [ 6 , 9 , 10 ]. Determination of the hybrid layer’s integration mechanisms (molecular bounding), evaluation of its chemical composition and quality can be successfully performed based on FTIR chemical mapping technique [ 11 , 12 ].…”

Engineering of a Biomimetic Interface between a Native Dental Tissue and Restorative Composite and Its Study Using Synchrotron FTIR Microscopic Mapping

“…In general, micro-mechanical bonding/adhesion occurs between the restorative material and the etched apatite prisms via formation of a hybrid layer within the demineralised collagen network [ 3 , 8 , 9 , 10 ]. The interface quality and affinity of the hybrid layer for the restorative material, which is determined by complex molecular interactions between the bond and the natural dental hard tissue, influence the longevity of the dental restoration [ 11 , 12 ]. Existing defects in the dentine/dental material interface prevent sustainable enamel/dentine restoration [ 4 , 13 , 14 ].…”

“…Modern hybrid layer formation strategies rely on nanotechnology [ 11 , 12 , 16 ]. Engineering an optimal hybrid biointerface requires materials having: (1) maximum affinity for natural enamel and dentine apatite and (2) similar morphological features and chemical composition as the natural amino acid matrix [ 17 , 18 , 19 ].…”

“…This system improves integration of the synthetic materials [ 17 , 20 , 25 ], making the transitional hybrid layer less problematic for restorative dentistry [ 11 ]. Alkaline media has also proven beneficial in biomimetic systems, as it mimics the properties of the enamel matrix or dentine to support stable bond formation at the biointerface [ 12 , 21 ].…”
