هدفت الدراسة إلى تقييم تأثير التخريش المسبق بحمض الفوسفور على التسرب الحفافي للمادة الرابطة ذاتية التخريش AdhesE في الأسنان المؤقتة. تشمل الدراسة 50 سناً مؤقتاً (أرحاء، أنياب) قلعت لأهداف تقويمية بحيث تكوف خالية من النخور و التصدعات و الكسور . تم تجميع العينات في جامعة حماه- قسم طب أسنان الأطفال . حضرت حفر صنف خامس في جميع العينات .
The purpose of this study was to evaluate the effect of preetching with phosphoric acid on microleakage of self-etch adhesive material Adhes E in primary teeth. The study involve 50 primary teeth(molars ,canins )which extracted for orthodontic reasons had no caries ,fractures ,crack. The teeth were gathered in Hama university-pediatric dentistry department. Class v cavity prepared in all samples.

The purpose of this study is to detect the relationship between dentin
bonding systems (total etch and self etch) and the marginal leakage of
composite resin restorations.
The etching primary teeth dentin is more important factors for bonding
composit with primary teeth dentin.
objective: The aim of this research is to know the effect of time etching with the phosphoric acid 37% by
duration (7 or 15 seconds) for the composite bonding strength with primary molar dentin towards shear
strength.
The purpose of this study was to compare the shear bond
strength to root dentin of a nano- ionomer material (Ketac N100,3M) and a
fifth generation bonding material (Excite,Vivadent) applied with a resin
composite (Tetric-ceram,Vivadent), in order to determine the material of
choice for restoring root extended lesions.
Etching by phosphoric acid is considered an important factor to achieve
resin bonding to Primary enamel.
Bond strength was significantly higher in the third group (etching for
35sec) than the other groups (etching for (15), (25), or (45)sec).
The
re were no significant differences in bond strength between etch
durations: (15), (25), or (45) sec.
Pulpectomy was performed on 100 primary teeth and the radiograph
was exposed immediately post treatment to observe weather the root
canal filling was: flush-undefiled or overfilled.
Teeth were examined periodically, clinically and radio graphically to
assess success of the treatment.
