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.

ABSTRACTObjectives: The purpose of this in vitro study was to evaluate whether mechanical alteration of the enamel surfaces with air abrasion and bur abrasion techniques could enhance the bonding performance of a three step and a self etching adhesive resin systems to enamel.Methods: 126 extracted lower human incisor teeth were used. The teeth were divided into three groups including 40 teeth each. First group; teeth were used as control and no preparation was made on enamel surfaces, 2nd group; outer enamel surfaces were air abraded, 3rd group; outer enamel surfaces were abraded mechanically with a diamond fissure bur. Cylinder composite resin blocks were bonded to the buccal enamel surfaces with two bonding systems (20 specimens in each group). Bond strengths to enamel surfaces were measured at a cross-head speed of 1 mm/min. The data were analyzed by ANOVA and Duncan Tests. To examine interface composite resin/enamel surfaces at scanning electron microscopy, remaining 6 teeth were used. Fracture analysis was performed using an optical stereomicroscope.Results: Bond strengths values of Solid Bond were significantly higher than bond strengths of Clearfil SE Bond for all types of enamel (P<.05). Shear bond strength values obtained with Solid Bond (three step system) to three types of enamel surfaces [air-abraded (30.25±7.00 MPa), bur-abraded (29.07±3.53 MPa), control (31.74±7.35 MPa)] were close to each other (P>.05). The macroscopic mode of failures for bonding systems, SB and SE Bond appeared to be adhesive and cohesive in nature.Conclusions: In order to get better bond strength values with self etching systems, it is advisable to prepare enamel surfaces with bur or air abrasion, but it enamel preparation is not necessary for three step systems.

Dogs were utilized in a study to compare the bond strengths of dentin bonding agents made to dentin in vivo and then again in vitro in the same teeth 30 min, one day, one week, and one month post-extraction. No statistically significant differences were observed between bonds made in vivo and those made in vitro at any time period. Contamination of the dentin surfaces with blood or saliva lowered the bond strengths, but these could be restored to control values by re-surfacing of the dentin with a bur.

<p><strong>Objective: </strong>The objective of this <em>in vitro</em> study was to compare dentin bonding systems and composite resins based on their functional groups in terms of water sorption (WS) and water solubility (WSB). <strong>Material and Methods: </strong>Three dentin bonding systems (Adper Single Bond 2 – 3M ESPE, Clearfil SE Bond – Kuraray, P90 Adhesive System – 3M ESPE) and three commercial composite resins (Filtek Z350 – 3M ESPE, Filtek Z250 – 3M ESPE, Filtek P90 – 3M ESPE) were tested. Eight specimens of each material were prepared to evaluate the WS and WSA. The discs were individually stored in a desiccator until constant mass was achieved. Specimens were then individually stored in distilled water until the mass was stabilized again. Finally, the specimens were dried again in the desiccator until constant mass was obtained. WS and WSA were calculated from these measurements. Data were analyzed by one-way ANOVA and Tukey post hoc test (p &lt; 0.05). <strong>Results:</strong> Filtek Silorane-Bond presented the lowest values of WS, and Clearfil SE Bond presented the lowest WSB. Filtek Silorane resin showed the lowest WS and WSA results. <strong>Conclusion:</strong> Based on the results, it can be concluded that the WS and WSB were influenced by the composition of the materials. The main functional group of the materials determines their susceptibility to water and influences their performance. </p>
