The Objective is to determined whether enamel conditioning with sodium
hypochlorite (5,25%) and EDTA prior to etching was increased shear
bond strength of orthodontic brackets bonded with resin – modified glass
ionomer. our sample consisted of 42 extracted human premolars were
randomly divided into 3 groups.
Objective: To compare effect laser Er:Yag and polyacrylic acid on
microleakage of of resin-modified glass-ionomer cement.
Analysis of variance shows no statistical differences between
three groups .
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 aim of this in vitro study was to evaluate the
microleakage on the gingival margin located below the cemento-enamel
junction of class II composite restorations (CR ,Tetric-ceram,Vivadent)
applied with a 5th generation bonding material (Excite,Vivadent) and to
compare it with that seen in open sandwich restorations using a
nanoionomer material (OST ,Ketac N100,3M) and a composite material
(Tetric-ceram).
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.
