TLDR
Besides self-etching dentin, specific functional monomers have additional chemical bonding efficacy that is expected to contribute to their adhesive potential to tooth tissue.Abstract:
Mild self-etch adhesives demineralize dentin only partially, leaving hydroxyapatite around collagen within a submicron hybrid layer. We hypothesized that this residual hydroxyapatite may serve as a receptor for chemical interaction with the functional monomer and, subsequently, contribute to adhesive performance in addition to micro-mechanical hybridization. We therefore chemically characterized the adhesive interaction of 3 functional monomers with synthetic hydroxyapatite, using x-ray photoelectron spectroscopy and atomic absorption spectrophotometry. We further characterized their interaction with dentin ultra-morphologically, using transmission electron microscopy. The monomer 10-methacryloxydecyl dihydrogen phosphate (10-MDP) readily adhered to hydroxyapatite. This bond appeared very stable, as confirmed by the low dissolution rate of its calcium salt in water. The bonding potential of 4-methacryloxyethyl trimellitic acid (4-MET) was substantially lower. The monomer 2-methacryloxyethyl phenyl hydrogen phosphate (phenyl-P) and its bond to hydroxyapatite did not appear to be hydrolytically stable. Besides self-etching dentin, specific functional monomers have additional chemical bonding efficacy that is expected to contribute to their adhesive potential to tooth tissue.read more

A Critical Review of the Durability of Adhesion to Tooth Tissue: Methods and Results
J. De Munck,K.L. Van Landuyt,Marleen Peumans,André Poitevin,Paul Lambrechts,M Braem,B. Van Meerbeek +6 more
TL;DR: This paper critically appraises methodologies that focus on chemical degradation patterns of hydrolysis and elution of interface components, as well as mechanically oriented test set-ups, such as fatigue and fracture toughness measurements, to assess adhesion durability.

Buonocore memorial lecture, adhesion to enamel and dentin: current status and future challenges
Bart Van Meerbeek,Jan De Munck,Yasuhiro Yoshida,Satoshi Inoue,Marcos A. Vargas,Padmini Vijay,Kirsten Van Landuyt,Paul Lambrechts,Guido Vanherle +8 more
TL;DR: The basic bonding mechanism to enamel and dentin of these three approaches is demonstrated by means of ultramorphological and chemical characterization of tooth-biomaterial interfacial interactions and confirms that conventional three-step etch&rinse adhesives still perform most favorably and are most reliable in the long-term.
