Short resin-posts bonding to primary dentin. Microleakage and micro-morphological in vitro study.
The aim of this in vitro study was to evaluate the adhesion of two bonding systems (Single Bond and Adper Prompt L Pop, 3M ESPE) to short resin posts in the root dentin of primary teeth. Statistical analysis (Mann Whitney) revealed that there were no statistically significant differences between the materials (p= 0.75), but the Single Bond group presented a wider resin-dentin inter-diffusion zone (RDIZ). Both groups showed long resin tags. It was concluded that although Single Bond produced a wider adhesive interface than Adper Prompt L Pop, leakage levels occurred in both systems.
