تهدف هذه الدراسة لمعرفة تأثير لون لواصق (Variolink Veneer) (V.V) المُستخدمة في إلصاق الوجوه الرقيقة على لون هذه الوجوه المُصنعة حصراً بخزف (IPS e-max). استخدمت عينة مؤلفة من (15) وجهاً رقيقاً بألوان (A1-A2-A3-A3,5) وفقاً لتقنيةIPS e-max Press))و(15( وجهاً رقيقاً وفقاً لتقنية (IPS e-max CAD). تم قياس لون هذه الوجوه على الأسنان المحضرة دون إلصاق وقياس المتغيرات الناتجة بين اللون المطلوب واللون الناتج بواسطة جهاز(Easyshade compact), ثم تم إلصاق كل ثلث من العينة الأولى والثانية بأحد لواصق(V.V) بإحدى درجات الشفوفية التالية(+3),(0),(-3) وتمت إعادة قياس المتغيرات بين اللون الناتج لكل مجموعة مع اللون المطلوب. بينت النتائج أن اللاصق (V.V-3)قد قدم النتائج الأكثر مقاربة للون المطلوب, فيما بينت أن اللاصق (V.V+3) قد قدم النتائج الأقل مقاربة, وبينت المقارنة بين التقنيتين أن تقنية (CAD-CAM) كانت أكثر مقاربة للون المطلوب من تقنية (Press), وبالتالي تكون تقنية (CAD-CAM) مع لاصق (V.V-3) هي الأكثر مقاربة في جميع الفئات.
This study aims to recognize the effect of Variolink Veneer (V.V) cement colors used in luting thin veneers fabricated from (IPS e-max) porcelain on the final resulting color. A sample of (30) thin veneers in (A1-A2-A3-A3,5( colors is used. The veneers were equally divided into two subgroups; the first was manufactured with(Press) technique and the second was manufactured with(CAD-CAM) techniques. The changes between the desired and resulting color are measured for without luting by the(Easyshade Compact) device. Each third of every subgroupwasthen luted with one of the colors of (V.V) (+3),(0),(-3), changes in color were re-measured. Results showed that (V.V-3) presents the favoredresults, while (V.V+3) offers the less favoredresultsfor the desired color. A comparison between the two techniques,showed that (IPS e-max CAD) provides the most favored result more than (IPS e-max press), that is why, (CAD) with (V.V-3) is the best in all combinations

Usually, it's hard to reach the final color identity with normal teeth when using
full glass ceramic, but this matter is very important for the cosmetic successful of these restorations. This
in vitro study evaluated the effect of cement color on the final color of full crown glass ceramic of system
IPS e.max.
The aim of this study is to evaluate the healing after
apicectomy by using two different techniques. And to evaluate the
effect of MTA as a retrograde filling material and also the Er:YAG
laser as a tool for resecting the apex, and the influence of them in
the healing.
Hyperimmunoglobulin E (Job) syndrome is considered to be a relatively rare
disease. Its characterized by recurrent infections in skin (eg. boils, abscesses), recurrent upper respiratory
tract infections (eg. otitis media, sinusitis and mastoiditis)
, and lower respiratory infections (eg. recurrent
pneumonia, which is often complicated by pneumatoceles and lung abscess), that are usually difficult to
treat. The highly increased IgE levels are considered to be the hallmark of the disease. The syndrome has
two types: one is inherited as an autosomal recessive, and the other, as an autosomal dominant trait.
To highlight the clinical manifestations and laboratory findigs of Job disease, and to compare it with
medical literature, to study the bacterial complications and differrent types of antibacterial treatments
and treir results, and to increase the level of awareness among physicians.
Experimentally induced inflammation of the gingiva of wistar rats Shown
remarkable increase in prostaglandins E. Adminstration of endometacin drug at
the stage of acut inflammation has led to a dicrease of prostaglandins E level in
the gingiva and
the improvement of the periodontal inflammation and the general
state of the animal .
This research has proved the importance of increasing biosynthesis of
prostaglandin E (and consequently the increase of prostaglandin E in the gingiva)
in the begening and development of periodontal inflammation , in addition to the
importance using prostaglandins synthesis inhibitors in the treatment of this
disease .
One of the challenges to the operation of a large and interconnected power systems is to insure that generators will remain in synchronism with one another following large disturbances such as short circuits on transmission lines and bus bars with as
sociated operation of protection system.
In this research, the impact of short circuits and their sustained duration on Syrian power system was analyzed through the dynamic simulation of three-phase faults at substations with varying fault clearance time at these substations.
In addition, critical fault clearing times on 230kV, 400kV network and substation bus bars were determined, as well as the influence of distance protection and bus bar differential protection on Syrian power system.
