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

Research summary
تهدف هذه الدراسة إلى تقييم تأثير لون لواصق الراتنج المستخدمة في إلصاق الوجوه الرقيقة المصنوعة من خزف IPS e-max على اللون النهائي لهذه الوجوه. تم استخدام عينة مكونة من 30 وجهاً رقيقاً بألوان مختلفة، وقسمت إلى مجموعتين؛ الأولى صنعت بتقنية الضغط (Press) والثانية بتقنية الخراطة الحاسوبية (CAD-CAM). تم قياس التغيرات اللونية باستخدام جهاز Easyshade Compact قبل وبعد الإلصاق. أظهرت النتائج أن اللاصق بدرجة شفوفية -3 (V.V-3) قدم أفضل النتائج، بينما اللاصق بدرجة شفوفية +3 (V.V+3) قدم أسوأ النتائج. كما بينت الدراسة أن تقنية CAD-CAM كانت أكثر دقة في مقاربة اللون المطلوب مقارنة بتقنية Press، مما يجعلها الخيار الأفضل عند استخدام اللاصق V.V-3.
Critical review
دراسة نقدية: تعتبر هذه الدراسة ذات أهمية كبيرة في مجال طب الأسنان التجميلي، حيث تقدم معلومات قيمة حول تأثير لون اللاصق على اللون النهائي للوجوه الرقيقة. ومع ذلك، يمكن توجيه بعض النقد البناء للدراسة. أولاً، حجم العينة قد يكون غير كافٍ لتعميم النتائج على نطاق أوسع. ثانياً، لم تتناول الدراسة تأثير العوامل البيئية مثل الإضاءة ودرجة الحرارة على اللون النهائي، مما قد يؤثر على دقة النتائج. وأخيراً، كان من الممكن تضمين مقارنة مع مواد لاصقة أخرى غير Variolink Veneer للحصول على صورة أشمل.
Questions related to the research
  1. ما هي التقنية التي قدمت أفضل نتائج لونية في الدراسة؟

    تقنية الخراطة الحاسوبية (CAD-CAM) قدمت أفضل نتائج لونية عند استخدام اللاصق بدرجة شفوفية -3 (V.V-3).

  2. ما هو جهاز القياس المستخدم في الدراسة؟

    تم استخدام جهاز Easyshade Compact لقياس التغيرات اللونية.

  3. ما هي العوامل التي تؤثر على اللون النهائي للوجوه الرقيقة؟

    العوامل التي تؤثر على اللون النهائي تشمل لون وظلالية المادة الخزفية المستخدمة، لون البنية الواقعة تحت الوجوه، ولون وتخانة المادة اللاصقة.

  4. ما هي توصيات الدراسة بخصوص استخدام تقنيات الإلصاق؟

    توصي الدراسة باستخدام تقنية CAD-CAM مع اللاصق بدرجة شفوفية -3 (V.V-3) للحصول على أفضل نتائج لونية.

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.
