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 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 effectiveness of the bacterial plaque adjacent orthodontic
brackets which bonded with fluoride releasing resin-based
composite was studied to evaluate the ability of this bonding
material in the control of caries process.
128 orthodontic brac
kets were bonded on 128 second premolars in
32 patients by using conventional composite in one group and
fluoride releasing resin-based composite in other group using the
split-mouth technique.
Since the solution of direct bonding of orthodontic brackets as an alternative to full encircling of the dental arch, researchers have begun conducting studies to evaluate the adhesion materials and different methods of enamel preparation to reach the most appropriate method for the requirements of ideal adhesion.
A study was conducted to investigate the protective and therapeutic
effects of Ecballium elaterium juice against experimental infection
with Eimeria stiedae in rabbits. Thirty- two rabbits were divided
into four groups (eight rabbits in each group
) : healthy control group
(HC); challenged – Ecballium elaterium –protected group (CEEP)
which received a daily dose of (45) μl\kg body weight Ecballium
elaterium juice intra-peritoneal for five days before challenged with
E. stiedae ; challenged – Ecballium elaterium –treated group
(CEET) which received a daily dose of (45)μl\kg body weight
Ecballium elaterium juice intra-peritoneal for five days after
challenged with of E .stiedae and infected group (IC).The challenge
dose was 40000 sporulated E. stiedae oocyst per rabbits.
