Immediate Dentin Sealing or pre-hybridization implies the application of resin adhesive to freshly cut dentin after teeth preparation, before impression. Immediate Dentin Sealing has been suggested as an alternative to the delayed dentin sealing (DDS), a technique in which resin adhesive is applied just before final bonding of indirect restorations. Immediate Dentin Sealing technique is universal i.e used in inlays, onlays, veneers, crowns and well documented clinically and experimentally. Various types of Dentin Bonding Agents are available on the market. Difference lies in the thickness of hybrid layer formed and the adhesive used.

INTRODUCTION: The adhesive dentistry developed materials and techniques capable to preserve the dental tissues through the union of substrate with adhesive resinous systems. Modernly the resinous components are used in direct adhesive restorations, in orthodontic brackets´ luting, in indirect restorations´ luting, in canal root filling, in sealing areas of bad coalescence like pit and fissures, among others. OBJECTIVE: The aim of this study was to do a review about the evolution of adhesive systems and to discuss the main efforts of the present time in perfecting them in the sense of minimizing their inconveniences. METHODS: Selection of papers through electronic bases LILACS and PubMed/ MEDLINE using indexing terms like: dentin-bonding agents, adhesives and hydrolysis among the years of 1999 and 2016. RESULTS: The adhesive systems have been reason studies in the sense of preserving the existent interface between the composed resin and enamel and dentine. That union presents problems as: hydrolytic degradation, separation of phases among hydrophilic and hydrophobic components, homogeneity lack in the formation of hybrid layer, exhibition of collagenous fibrils no completely involved by the monomers to be polymerized, leaching monomers, differences in osmotic concentration gradient, difficulty of larger intimacy among organic and inorganic materials, interaction or removal of the smear layer and presence of quiescent bacterias in adhesive interface. The largest inconveniences are: nanoleakage, with bacterial invasion and secondary decays. CONCLUSIONS: To know the progresses in the dentin-bonding agents and how to use them correctly is fundamental for a favorable prognostic of the quality of adhesive aesthetic restorations.

The formation of a hybrid layer is the main bonding mechanism of current dentin-bonding systems. This study evaluated the morphology and thickness of the resin-infiltrated dentinal layer after the application of adhesive systems. The dentin-bonding agents were evaluated on flat dentinal preparations confected on the occlusal surfaces of human teeth. The test specimens were prepared and inspected under scanning electron microscopy at a magnification of X 2,000. The adhesive systems were responsible for different hybrid layer thicknesses (p < 0.05), and the mean values were: for Scotchbond MP Plus (SM), 7.41 ± 1.24mum; for Single Bond (SB), 5.55 ± 0.82mum; for Etch & Prime 3.0 (EP), 3.86 ± 1.17mum; and for Clearfil SE Bond (CB), 1.22 ± 0.45mum. The results suggest that the conventional three-step adhesive system (SM) was responsible for the thickest hybrid layer, followed by the one-bottle adhesive (SB). The self-etching adhesives, EP and CB, produced the formation of the thinnest hybrid layers.

ABSTRACTObjective: The purpose of this in vitro study was to explore the radiopacity of composite resins and bonding materials using film and phosphor plates.Methods: Nine composite dental resin specimens and human tooth slices were exposed together with an aluminium stepwedge using dental film and phosphor plates. Eight dentin bonding specimens were prepared and exposed in a similar manner. Their radiopacity on film was assessed using a transmission densitometer, and the radiopacity with phosphor plates was assessed digitally using the system’s own software (Digora). Data were analysed using one-way analysis of variance (ANOVA) and post-hoc Tukey tests (P<.05). Film and phosphor plate radiopacity values were compared using simple regression analysisResults: Excellent linear correlation was found between film and phosphor plates for both composite resins and bonding agents. The composite materials Spectrum Tph and Natural Look exhibited the highest radiopacity with film and with phosphor plates, respectively. All the dentin bonding agents tested exhibited lower radiopacity than dentin. Conclusion: Synergy, Ice, Filtek Silorane, Filtek Z250, Clearfil Majesty Posterior, Herculite Classic, Spectrum Tph, and Natural Look composite materials exhibited greater radiopacity than dentin, and all the dentin bonding agents tested exhibited lower radiopacity than either enamel or dentin.
