هدفت الدراسة إلى مقارنة التسرب الحفافي للمادة السادة الراتنجية Helioseal F مع أو بدون إضافة مادة رابطة. تم جمع 67 ضاحكة علوية من الأسنان البشرية السليمة المقلوعة حديثا لأسباب تقويمية، ثم قسمت عشوائيا إلى مجموعتين رئيستين متساويتين، مجموعة طبقت فيها المادة السادة Helioseal F بدون مادة رابطة و مجموعة طبقت فيها المادة السادة Helioseal F مع مادة رابطة Tetric N Bond.
The aim of this study was to compare microleakage of resin-based sealant Helioseal F with or without bonding agent. Fifty-six sound human maxillary first premolar teeth were collected which were extracted for orthodontic purpose, then the teeth were randomly divided into two main equal groups; group (1) and group (2), the first group was treated with Tetric N Bond bonding agent, whiles the second group without.

During the previous decade, resins were widely used in the restoration of posterior teeth, as it was found that wear occurs in the abrasive and adjacent section of resin-based restorations, while in the marginal areas, marginal leakage was observed.
Regarding the sealing ability of restorative dental materials, this
study was done to assess the microleakage of class V cavities
restored with a new self-adhesive flowable composite resin and
compare to different flowable materials.
The aim of this in vitro study was to determine the effect of fissure
types on the microleakage, and penetration ability of fissure sealant.
The occlusal surface of ninety caries-free extracted human upper
premolars were cleaned, etched and sealed
with (UltraSeal XT
Plus) Sealant. The sealed teeth were thermocycled then coated with
two layers of nail varnish, leaving exposed a 1 mm window around
the sealant margins and then immersed in 1% methylene blue for 24
hours. Each tooth was sectioned bucco-lingually and examined with
a stereo microscope (40x magnification) for fissure types,
microleakage, and penetration ability.
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).
The aim of this study is to evaluate the microleakage
resultant from; Silorane resin composite restorations in primary
teeth Prepared Using Burs And Er:YAG Laser with or without
using additional etching.
