The Purpose of this study was to evaluate and compare the shear bond strength
(SBS) of two composite repair systems to zirconia-ceramic with and without sandblasting.
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).
This study aims to evaluate zirconia bond strength bonded with resin cement
after deferent surface treatments.
The purpose of this study was to evaluate the shear and tensile bond strengths of orthodontic
brackets bonded with self etching primer and resin-reinforced glass ionomer cement in comparison with
light cured resin adhesive.
The tested self-etching
primer and adhesive systems produced bond strength values higher than that of the light cured resin
adhesive whereas the resin-reinforced glass ionomer cement showed a significantly reduced bond strength
. Clinically, the use of self-etching primer and adhesive systems is suitable for orthodontic bracket
bonding.
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.
The aim of this study To compare in vitro shear bond strength (SBS) of different
orthodontic adhesives in and rebonding metal brackets after preparing their bases
mechanically.
Material and methods:Sample consisted of 40 extracted first premolars,
randomly
divided into two groups (n=20),.Adhesive removed by tungsten carbide bur later the
brackets were rebonded. The tests were performed in a tecnotest (6kN) SBS testing
machine, at a speed of 1 mm/min.
It was found that the mean shear bond strength of Reseliencewas 19.25 MPa and that
of Heliosit orthodontic was 10.25MPa.We foundthat the mean shear bond strength of
rebonding forReselience was 13.70 and 7.95 forHeliosit.The t-test revealed that there was a
significant difference between the shear bond strength of the two groups.
We found a significant difference between bonding and rebondingfor
Reselience,while there was no significant difference between bonding and rebonding for
Heliosit.
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.
The of this study was to evaluate the bonding strength of a
posterior composite restorations when two different types of
equipment methods were used for preparation of dentin (Erbium-doped
yttrium aluminum garnet laser (Er:YAG ) and diamond burs).
This study specimen consisted of Eighty molars, was divided
randomly into two main groups (40 molars were prepared with
diamond burs, and 40 molars were prepared with laser Er: YAG).
This study aimed to compare the effects of different enamel
etching techniques for bracket bonding strength. The sample
consisted of eighty human premolars were randomly divided into
four equal groups. The enamel surfaces of the teeth were etched
with 35% orthophosphoric acid in Group 1 , air abraded with
50 μm aluminum oxide prior to acid etching in Group 2, Trans
bond Plus Self-etching Primer (TPSEP) in Group 3 , Er: YAG
laser in Group 4. After enamel etching procedures, brackets were
bonded with Trans bond XT , then shear bonding test was
performed using a testing machine (Tinius Olsen).
