Tensile bond strength of different adhesive systems to enamel and dentin

Abstract

The aim of this study was to assess the tensile bond strength of four adhesive systems to enamel and dentin: Clearfil Liner Bond 2V -C, Prime&Bond NT/NRC -PB, Single Bond -SB and All Bond 2 -AB. For such purpose, 40 sound human molars were selected. Crowns were bisected in a mesiodistal direction and each half was ground until flat enamel (E) or dentin (D) surfaces were obtained. A total of 80 specimens were randomly assigned to 4 groups (n=20, 10 in enamel and 10 in dentin). After surface treatment, a composite resin (Z250; 3M) cone was prepared using a split Teflon ® matrix. Bond strength was tested in an universal testing machine (0. . Statistical analysis of data by two-way ANOVA showed that C presented the best results followed by SB. In conclusion, among the tested materials, Clearfil Liner Bond 2V self-etching primer adhesive syetem had the best performance. The substrate type influenced bond strength, being higher to enamel.

Shear Bond Strength of Self-Adhering Flowable Composite on Dentin with and without Application of an Adhesive System

“…Some new materials may be stronger and bond better to tooth substrates than currently available materials, and laboratory evaluation provides the first means of assessing differences in material properties (21,22). Bond strength assessment is the most common laboratory test used in evaluating the adhesive properties of restorative materials and has become a well-recognized method for assessing material performance in the laboratory (23)(24)(25). In this study, SBS testing was used to compare the adhesive properties of self-adhering flowable resin composites and conventional flowable composite on both primary and permanent tooth dentin surfaces.…”

The Evaluation of Bond Strength of a Composite and a Compomer to White Mineral Trioxide Aggregate with Two Different Bonding Systems

“…The most common method to evaluate adhesive properties of restorative materials is bond strength assessment. This has become a well-recognized method to analyze an important part of the in vitro performance of materials (14,15). So the shear bond strength test has been used in this study to evaluate the adhesive properties of WMTA to composite and compomer restorative materials.…”

Influence of water storage time on the bond strength of etch-and-rinse and self-etching adhesive systems

“…There was no significant difference for ASB2 when stored for either the short-or long-term period, demonstrating a favorable behavior and a potential preservation of bond stability in a degrading medium. This result can be explained by the fact that this material contains ethanol as a solvent, which favors its use in the wet bonding technique, and by the active form of application, since this organic solvent rapidly mixes with water and facilitates evaporation within the time recommended by the manufacturer (19).…”
