Shear bond strength of different dentin substitute restorative materials to dentin of primary teeth.

This in vitro investigation compared the shear bond strength (SBS) of four dentin substitute/replacement materials to caries-affected dentin of primary teeth. Dentin surfaces were randomly divided into four groups of 12 each according to the material used as follows: SDR/Smart Dentin Replacement, Biodentine, Multicore Flow, and Fuji II LC. The SBS was measured and failure modes were determined.
