تهدف هذه الدراسة إلى تقييم و مقارنة تأثير سوائل الإرواء على مقاومة انحناء العاج . حيث تم جمع ( 20 ) رحى ثالثة مقلوعة من فئة عمرية 18-24 سنة و تم تصميم القضبان العاجية التي سوف تجرى عليها الدراسة بأبعاد متشابهة و هي ( عرض 1 ملم , ثخانة 2 ملم , طول 7 ملم على الأقل ).
The aim of this study was to evaluate and compare the effect of irrigation solutions on the dentin flexural strength .(20) extracted third molars were gathered with age avarege (18-24) years old, and the dentine bars that will be prepared and designed for study with similar dimensions (width 1 mm, thickness 2 mm, Length of at least 7 mm).

Objective: the Purpose of this study was to evaluate in vitro the
apical microleakage of methacrylate risen-based sealer (EndoREZ )
after root canal irrigation with sodium hypochlorite or chlorhexidine
digluconate.
Ready made post design plays an important role with resin cement ability on
post retention in to the root canal. While the paraposts are the most retentive.
To compare the resistance of serrated Para post, tapered-smooth, and threaded para posts, c
emented with
panivia21 to transverse load.
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

This study compared the durability of a cast metal wedge restoration, a cast metal endocrown restoration, and a method of constructing a composite resin core without a root wedge when applying 45-degree inclined compressive forces using a mechanical testing device.
Resin based composite considers substantially as a restorative
material in clinic. Dentists concern in placement resin composite
restorations with Long term survival.
Materials and Methods: 20 Non carious human third molars, class I
cavity was pr
epared in every molar, restored with methacrylate
resin composite Tetric EvoCeram. The restored teeth were
subjected to thermocycles. Specimen was randomly divided into
two groups : the first group 10 restorations, were repaired by
Cojet® (3M ESPE, Germany) and restored by Filtek™ P90, the
second group 10 restorations also repaired by Cojet ® but restored
by Filtek™ Z350 XT. After that all teeth were subjected to
thermocycles again, later immersed in 0.5% basic fuchsin solution
for 1 s. The teeth were transversely sectioned and observed under
a stereomicroscope. The degree of dye penetration was recorded
and analyzed.
Results: No statistically significant differences in microleakage
were observed between two groups either with low shrinkage
Silorane resin composite or methacrylate resin composite
