The purpose of this in vitro study to evaluate the effect
of ceramic primer on the bond strength of adhesive resin cement to
zirconia ceramic surface.
The leishmaniasis is a serious health problem in Syria, due to the
wide spreading of Leishmania tropica parasite , the difficulty of
controlling the reservoirs of parasites, and there is no specific ,safe
and active therapy .Due to lack of studies
of Leishmania tropica
genome , as initial step we detect the presence of SW3 gene.
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).

Background
Resin bonded fixed partial dentures appeared to prevent the excessive preparation of dental
tissue
Investigation of surface treatments to improve the bond of resin cements to metals may contribute
to the longevity of these restoration
s. Due to the potential lack of ideal preparation form the type of alloy
and its surface pretreatment may have clinically relevant correlations with the retentive strength of castings
to minimally retentive preparations
Aim
The aim of this search is to study the bonding resin cement strength to different types of the metal
alloy due to the surface treatment
Purpose Evaluate the effects of two different surface treatments on shear bond strength SBS between a
palladium silver alloy Pb Ag and commercially pure titanium CP Ti cast alloy with resin luting cements

Partial veneer crown has appeared to prevent the excessive preparation of
dental tissue with complete crown and the major reason success of this prosthesis could be strength of
cementation.
Therefore the latest studies have been focusing on develo
ping new material and technique to increase the
bonding strength and using new technique for surface treatment or change type of metal alloy.
The aim of this search is to study the bonding resin cement strength to different type of metal alloy due to
surface treatment.
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.
