تبدلات الميناء بعد التطبيق الموضعي لعوامل التبييض تسبب عواقب أساسية منها : تحرير الشوارد، تزايد الخشونة السطحية، و التصاق بكتريا أقوى، و تبدل القساوة. الهدف من هذه الدراسة لتقييم تأثير عامل التبييض ( 35 % بيروكسيد الهيدروجين ) للأسنان الحية باستخدام مصدر تفعيل على تحرير الشوارد ( الكالسيوم و الفوسفات ) من سطح الميناء. تألفت عينة البحث من ( 30 سن ) بسطح مينائي سليم لمجموعة المراقبة ، و ( 30 سن ) بسطح مينائي سليم لمجموعة ( 35 % بيروكسيد الهيدروجين ) مع تطبيق تفعيل ضوء لتنشيط عامل التبييض.
Alterations of the enamel after topical application of bleaching agents, presenting as major consequences are: ions release, increased superficial roughness, stronger bacterial attachment and hardness alteration.The aims of the study were to evaluate the effect of the bleaching agent (35%hydrogen peroxide) for vital teeth by using light source on the release of ions from the enamel surface. our sample consisted of 30 sound enamel surface for control group,30 sound enamel surface for(35%hydrogen peroxide), and then application of light radiation to activate the bleaching agent. Ion Chromatography were used to measure the ions release .

since teeth whitening is very important procedure in dental office. the effect
of peroxides on enamel tissue is of great interest in research. The aim of this in vitro study was to perform
a qualitative analysis of the human enamel microhardness af
ter the application of high concentration of
hydrogen peroxide (38%)with and without light activation, using Vickers microhardness tests.
The research project sample consisted of 80 extracted central incisors obtained from the Oral and Maxillofacial Surgery Department as well as from private practices. These teeth were divided into two equal groups. The bonding agent ClearFil SE Bond w
as used in one group, whereas the OptiBond Solo Plus bonding agent was used in the other group. Each group was divided into four subgroups: (1) veneers performed without any bleaching, (2) veneers performed two weeks before bleaching, (3) veneers performed immediately following bleaching and (4) veneers performed two weeks after bleaching.
veneers were made using a special template which allowed producing the same size of all the specimens used in this project. These veneers were placed on the vestibular surfaces of enamel of the extracted central incisors.
The aim of the previous procedures was to study the effect of home teeth bleaching .
Teeth were embedded in acrylic blocks created in metallic cylinders. The bonding strength was measured through .
The results showed that there was a significant difference between the control subgroup and the second subgroup .
Background and Aim : Retention between composite and fiber post is still below the acceptable level when compared with the retention between composite and dental structure. This study aimed to evaluate the effect of H2O2 as a chemical solution to imp
rove the mechanical connection between fiber post and composite core. Materials and Methods:45 glass fiber posts and 45 quartz fiber posts were prepared. The specimens were randomly distributed into 3 subgroups, including application of silane (S) , etching with H2O2 10% for 20 minutes(H1) , etching with H2O2 20% for 10 minutes (H2). composite core was placed. Shear bond strength values of posts and composite resin cores were measured using a mechanical test machine (Instron). data were analyzed Statistically . Results :There were significant differences between the shear bond strength for (H1,H2) And (S) in quartz groups only (P<0.05). There was no significant difference between glass and quartz groups (P>0.05). Conclusions:The surface treatment of quartz fiber posts with H2O2 significantly enhanced the shear bond strength of the composite core. Application of H2O2 to the Glass fiber post surfaces was not effective.
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.
This study aims to evaluate zirconia bond strength bonded with resin cement
after deferent surface treatments.
