The aim of the work was to answer questions of clinical relevance using in
vitro testing methods. Moreover, this study was focused on the factors that
might affect the degree of primer or bonding resin infiltration into the
demineralized dentin and consequently could affect the bond. The methods
used to evaluate the bond between resin composite and dentin were the
bond strength test and scanning electron microscopic analysis. A
comparison was conducted between the shear test and the microtensile test.
The findings showed that both tests could be used without affecting the
results of the factors tested. It was preferable to use the microtensile test as
it has advantages over the shear test. The results showed that dwell time
was an important factor in achieving the bond. The scanning electron
microscopy was an efficient tool in assessing the quality of the bonding
zone, but it was not the ideal tool to measure quantitative data.
