“…Most laboratory enamel‐bond studies have been evaluated by using ground flat surfaces, regardless of the type of bond‐strength test . It is easy to standardize the methodology because an appropriate adherent area for the bonded assembly and uniform stress distribution can be achieved on a ground flat surface .…”

The purpose of this study was to determine the immediate bond effectiveness of universal adhesives to unground and ground enamel surfaces in different etching modes, through shear bond strength (SBS) tests and scanning electron microscopy observations. Three universal adhesives, a conventional two‐step self‐etch adhesive, and a conventional single‐step self‐etch adhesive were compared. Human enamel specimens from lower anterior teeth were divided into four groups and subjected to the following treatments: (i) unground enamel in self‐etch mode; (ii) ground enamel in self‐etch mode; (iii) unground enamel in etch‐&‐rinse mode; and (iv) ground enamel in etch‐&‐rinse mode. Bonded assemblies were subjected to SBS testing. All the adhesives showed significantly higher SBS values in etch‐&‐rinse mode than in self‐etch mode, regardless of whether enamel was unground or ground. The influence of the enamel surface condition on SBS was different in different etching modes. Without pre‐etching, all tested materials showed lower SBS values in unground enamel than in ground enamel. In etch‐&‐rinse mode, no significant differences in SBS values were observed between unground enamel and ground enamel for any of the adhesives tested. Phosphoric acid pre‐etching before application of self‐etch adhesives to an unground enamel surface is essential to enhance initial enamel bond effectiveness.

“…With continuously improving bonding technology, the adhesive-resin restoration strategy is being used more and more often in clinical practice due to the focus of less invasiveness and esthetic property [1]. Moreover, the long-term clinical success of adhesive restoration is primarily dependent on the bonding quality of adhesive systems to dentin, and the key parameter for evaluating the bond quality of different dentin-adhesives systems is bond strength [2]. However, it is difficult to obtain precise and consistent bond strength data due to the use of numerous testing techniques and parameters [3,4].…”

Abstract. The purpose of this study was to evaluate the bonding ability of four representative dentin-adhesive systems by applying the micro-shear bond strength (μ-SBS) test method and to evaluate the influence of adhesive area limitation on the bond strength. Two different adhesive application methods were used in the μ-SBS test (with and without adhesives area limitation), and four representative adhesive systems were used in this study. Each dentin surface was treated with one of the four representative adhesive systems, and with twenty samples per group (n=20), each of the four groups underwent a μ-SBS test. The results showed that the bond strength was significantly influenced by the adhesive application method (p<0.05), the adhesive type (p<0.05) and the interaction between the two factors (p<0.05). With regard to the four representative dentinadhesive systems, 3-E&R has a much better bond quality compared to the other adhesive systems. Furthermore, the microshear bond strength test method of restricting the area of both the adhesive and the resin is more reliable for evaluating the bonding property of adhesives to dentin, and it is also adequate for comparing the different adhesives systems.

“…Longevity of a restoration is predicted to some extent by its adhesive ability, and this in turn can be measured by bond strength testing 16) . Bond strength can predict the longevity of a restoration Shear bond strength of different dentin substitute restorative materials to dentin of primary teeth to some extent 19) . Although the correlation of bond strength assessments to foresee clinical performance of different restorations is questionable 20) , existing evidence indicate that clinical performance can be predicted by appropriate types of laboratory studies 1,21) .…”

This in vitro investigation compared the shear bond strength (SBS) of four dentin substitute/replacement materials to caries-affected dentin of primary teeth. Dentin surfaces were randomly divided into four groups of 12 each according to the material used as follows: SDR/Smart Dentin Replacement, Biodentine, Multicore Flow, and Fuji II LC. The SBS was measured and failure modes were determined. There was a statistically significant difference in the mean values of SBS among the four materials (F=741.523, p<0.0001). The mean values of SBS of SDR were statistically significantly higher followed by Multicore Flow compared to the other groups. The mean values of the four materials were significantly different from each other in all combinations of pairs of four materials. The SBS between the four dentin substitute/replacement materials to dentin of primary teeth was significantly different. The highest SBS was for SDR followed by Multicore Flow then Fuji II LC and the lowest was for Biodentine.
