The purpose of this study was to evaluate the performance of applications of using selfetching adhesives (
Prompt L-Pop®, 3M ESPE AG), when used with compomers and lightactivated restorative materials, in comparison to the performance of each restorative system adhesive. Evaluation parameters to be considered for the adhesive systems were (i) immediate marginal gap formation in tooth cavities and (ii) their immediate shear bondstrengths to enamel and to dentin.
For compomers and light-activated restorative materials, application of
Prompt L-Pop exhibited significantly superior marginal adaptation in the tooth cavity and enamel shear bond strength to most system adhesives. However, for dentin shear bond-strengths, there were no significant differences between
Prompt L-Pop® and each restorative system adhesives, for all materials tested except Hytac and UniFil F.
