Context:
Bonding agents have developed from a multistep bonding process to simplification, i.e. self-etch and single bottle system.
Aims:
The aim of this study is to compare and evaluate the shear bond strength (BS) of sixth-, seventh, and eighth-generation dentin bonding agents.
Settings And Design:
This was an in vitro study.
Materials And Methods:
Three sets of 75 permanent mandibular premolars that had been removed were chosen. A universal testing machine operating at a cross-head speed of 1 mm/min. examined the shear BS of the samples after they had been stored in deionized water for an entire day.
Statistical Analysis Used:
"One-way analysis of variance and Bonferroni test post hoc analysis" were used for statistically analyzing the data.
Results:
The sixth-generation group shear BS was noticeably stronger.
Conclusions:
The sixth-generation dentin bonding agent demonstrated the greatest mean shear BS to dentin because the solvent present had low concentration and low hydrophilicity, polymerization was more extensive, and dentin underlined underwent limited etching and demineralization over an extended period of time.
