Effect of Components of Dentin Bonding Systems on the Bonding Strength to Dentin and Enamel

This study aimed to investigate the effects of various compatible all-ceramic materials and bonding systems, on the bonding properties of dentin. Five types of commonly used all-ceramic materials (Cerec Blocs, IPS e. max Press, IPS e. max ZirCAD, Incoris Alumina, In-Ceram Alumina) were bonded with three types of adhesives (Multilink N, Variolink N, Relyx Unicem) for nuclear porcelain tile preparation. We evaluated the polymerization conversion rates, shear bonding strength (SBS), and micro-tensile bond strength (TBS) for each combination. The polymerization conversion rates, SBS and TBS differed significantly for all 3 adhesives with each all-ceramic group (P < 0.05). The Relyx Unicem agent had higher adhesive properties compared with the Variolink N and Multilink N agents (P < 0.05). The polymerization conversion rate, SBS and TBS of the five all-ceramic materials differed significantly with each adhesive (P < 0.05). The Cerec Blocs had the highest adhesive performance (P < 0.05). The polymerization conversion rate of adhesives differed with each all-ceramic material, while the dentin bonding strength differed with each all-ceramic material and adhesive. Clinically, all-ceramic materials with a high transparency and low refraction are recommended. For opaque all-ceramic restorations, the curing light time and polymerization reaction rate should be increased to improve the dentin bonding performance.

New Generation

In 1955, Buonocore introduced the etching of enamel with phosphoric acid. Bonding to enamel was created by mechanical interlocking of resin tags with enamel prisms. Enamel is an inert tissue whose main component is hydroxyapatite (98% by weight). Conversely, dentin is a wet living tissue crossed by tubules containing cellular extensions of the dental pulp. Dentin consists of 18% of organic material, primarily collagen. Several generations of dentin bonding systems (DBS) have been studied in the last 20 years. The dentin bond strengths associated with these DBS have been constantly lower than the enamel bond strengths. Recently, a new generation of DBS has been described. They are applied in three steps: an acid agent on enamel and dentin (total etch technique), two mixed primers and a bonding agent based on a methacrylate resin. They are supposed to bond composite resin to wet dentin through dentin organic component, forming a peculiar blended structure that is part tooth and part resin: the hybrid layer.

Bonding Systems

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.
