The aim of this study was to determine the influence of dentinal region on shear
bond strength by comparing the shear bond strength between root and coronal dentin when using a nanoionomer
material (Ketac N100,3M Espe) and a fifth generation bondin
g material (Excite,Vivadent)
applied with a resin composite (Tetric-ceram,Vivadent).
The purpose of this study was to compare the shear bond
strength to root dentin of a nano- ionomer material (Ketac N100,3M) and a
fifth generation bonding material (Excite,Vivadent) applied with a resin
composite (Tetric-ceram,Vivadent), in order to determine the material of
choice for restoring root extended lesions.
