Conclusions

Within the limitations of this in-vitro study, the following conclusions were drawn: 1. Photo-polymerization time had an effect on dentin SBS, with higher bond strength when photo- polymerization time was performed between 2 and 5 minutes with self-adhesive and between 0-2 minutes with adhesive resin cement.

2. Delaying photo-polymerization to 10 minutes lead to significant lower dentin SBS and Vickers micro-hardness for both adhesive and self-adhesive dual-polymerizing resin cements.
