The aim of the study is to evaluate the surface roughness of the resin Tetric N Ceram (Ivoclarvivadent ) after different finishing and polishing techniques. 50 specimens of (10×2) mm were made and distributed in 5 groups (N=10), According to the technique employed: First group G1: Tengustinecarbid burs, Second group G2: Astopol system, Third group G3: Stem discs, Fourth group G4: Tengustinecarbid burs then Astropol system, Fifth group G5: Tengustinecarbid burs then Stem discs. A coarse roughness diamond bur was applied , then applied a super fine diamond bur on all specimens of the study before starting any procedure of finishing and polishing. After finishing and polishing techniques, surface roughness )Ra μm( was measured using InfiniteFocus– Alicona. Data were subjected to Kruskal-Wallis and Mann-Whitney U test at 5% significance level.

Research summary
تهدف هذه الدراسة إلى تقييم خشونة سطح راتنج Tetric N Ceram بعد تطبيق تقنيات مختلفة للإنهاء والتلميع. تم تصنيع 50 عينة من الراتنج وتوزيعها على خمس مجموعات، حيث تم تطبيق تقنيات إنهاء وتلميع مختلفة لكل مجموعة. أظهرت النتائج أن المجموعة الثانية (نظام Astropol) والمجموعة الخامسة (سنابل تنغستين كاربايد مع أقراص Stem) حققتا أقل مستوى من خشونة السطح، بينما حققت المجموعة الثالثة (أقراص Stem) أعلى مستوى من الخشونة. تم استخدام جهاز InfiniteFocus لقياس خشونة السطح، وأظهرت التحليلات الإحصائية وجود فروق معنوية بين المجموعات المختلفة. خلصت الدراسة إلى أن نظام Astropol ونظام سنابل تنغستين كاربايد مع أقراص Stem هما الأكثر فعالية في تحقيق سطح ناعم لترميمات الكمبوزيت.
Critical review
دراسة نقدية: تعتبر هذه الدراسة مهمة في مجال طب الأسنان التجميلي، حيث تقدم معلومات قيمة حول تأثير تقنيات الإنهاء والتلميع على خشونة سطح ترميمات الكمبوزيت. ومع ذلك، يمكن تحسين الدراسة من خلال تضمين عينات أكبر وزيادة تنوع المواد المستخدمة. كما يمكن أن تكون الدراسة أكثر شمولية إذا تم اختبار تأثير هذه التقنيات على متانة الترميمات على المدى الطويل. بالإضافة إلى ذلك، يمكن أن تكون الدراسة أكثر فائدة إذا تم تضمين تقييمات سريرية من قبل أطباء الأسنان والمراجعين المستقلين.

Aim: to compare the effect of multiple usage and surface coarseness of diamond
burs on marginal microleakage of cervical resin composite restorations.
Materials and methods: sixty extracted premolars without caries were chosen. The
sample was rand
omly divided into three groups: n1=n2=n3=20. Group(1): class v cavities
were prepared using super coarse diamond burs, group(2): prepared by coarse diamond
burs, whereas group)3(: prepared by medium coarse diamond burs. All cavities were
restored by resin composite, then The teeth were thermocycled and immersedIn5%solution
of methylene blue dye for 12hours.Then the teeth were sectioned vertically, Dye
penetration was evaluated using a 10X stereomicroscope at the occlusal and gingival
margins. Data were collected and statistical analysis was conducted.
Results: The results showed that the multiple use of super coarse diamond burs
caused no significantly statistically affect on occlusal and gingival microleakage (P>0.05).
However, the multiple use of coarse and medium diamond burs caused significantly
statistically affect on gingival marginal microleakage (P<0.05).
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
The elapsed time is considered as an essential factor when some
procedures are required on resin composite restorations like
repairing, etc.., and the question is whether this factor is going to effect on using silorane resin composite.
Twenty sil
orane based resin composite blocks were prepared
(8×8×4)mm, randomly assigned into two groups: the first group 10 blocks, half of each resin block was removed by diamond burs after thermocycles, the second group 10 blocks also half of each resin block was removed by diamond burs after fabrication. All Interfacial surfaces were conditioned by (Cojet™, 3M ESPE). Blocks were restored with silorane resin composite and subjected to thermocycles. Microleakage observed under a stereomicroscope after blocks were immersed in 0.5% basic fuchsin solution for 10 s, and transversely sectioned.
Mann-Whitney U test found no statistically significant differences
in microleakage between two groups either with fresh silorane
resin composite group or aged silorane resin composite group.
The phenomenon of impact between the adjacent buildings is one of the most important reasons for collapse of buildings during the
earthquakes for that most of the codes resort to avoid impact by
increasing the distance between adjacent buildings, b
ut on the other hand high cost of land requires us to take advantage of the largest possible area in addition to the difficulty of making the separation architecturally and in particularly for high buildings the separation may offer up to 50 cm.
We tried to have this research one of the studies that discuss the
subject of seismic pounding where we discussed the methods for
modeling the pounding and the most appropriate way to study the impact depending on the program dynamic analysis Ansys
(Autodyn Ver. 11) then chose several cases for study seismic
impact in three-dimensional models to cover most of the study
variables that may affect this phenomenon, and we doer non- linear dynamic analysis for all cases, with applying acceleration function is defined by equation its constants are changing with processing the seismic records data.
After finishing the analysis for all the models we have discussed
changing the transitions and stresses and strains , and studied the
factors affecting the impact , and discussed results of study and
then we have summarizes the recommendations in that we see fit
through this search.
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.
