background and aims. nano-ionomer (ni) interacts with tooth structures superficially, and there is a concern about the enamel bonding ability of mild self-etch ketac primer. this study compared the effect of different adhesive procedures (self-etching and etch-and-rinse approach) on long-term marginal microleakage of nano-filled resin-modified glass-ionomer (ni) cervical restorations. materials...

Purpose This study evaluated the effects of different adhesive systems on repair bond strength of aged resin composites. Materials and Methods Ninety composite discs were built and half of them were subjected to thermal aging. Aged and non-aged specimens were repaired with resin composite using three different adhesive systems; a two-step self-etch adhesive, a two-step total-etch adhesive and...

microleakage can be responsible for tooth hypersensitivity, secondary caries, and the possibility of pathological pulp alterations in restored teeth. recently, alternative methods for tooth preparation such as laser irradiation have been studied; but there are limited studies on primary teeth. the aim of this in vitro study was to compare the degree of microleakage of composite restorations pre...

Background and Aim: Data regarding the efficacy of universal adhesives are limited. This study aimed to assess the durability of a universal adhesive bond to superficial dentin using etch and rinse and self-etch modes. Materials and Methods: In this in vitro, experimental study, 32 sound molars were randomly divided into two groups of Scotchbond Universal adhesive with two-step etch and rins...

Our experiment evaluated the microleakage in resin composite restorations bonded to dental tissues with different adhesive systems. 40 class V cavities were prepared on the facial and lingual surfaces of each tooth with coronal margins in enamel and apical margins in cementum (root dentin). The teeth were restored with Z100 resin composite bonded with different adhesive systems: Scotchbond Mult...

BACKGROUND To determine the shear bond strength and adhesive remnant index of a new premixed self-etching primer and adhesive (Tectosan, BonaDent, Germany) for orthodontic appliances in comparison to a reference total-etch system Transbond XT. METHODS Bovine incisors were embedded in resin and randomly divided into two groups of 16 samples each. Brackets (Discovery, Dentaurum, Germany) were b...

OBJECTIVE To evaluate the influence of Expasyl® gingival retraction paste on the shear bond strength of self-etch and total-etch adhesive systems. MATERIALS AND METHODS Twenty-four specimens of extracted, caries-free, sound human molars were used in this study. The molars were then cut vertically into halves through the buccal and lingual cusps. Forty-eight specimens were divided into four gr...

BACKGROUND This study was carried out to evaluate the nanoleakage of two types of nanofilled adhesive systems in Class V composite resin restorations. MATERIALS AND METHODS Totally 60 human premolars were randomly assigned to two groups (n = 30). Standardized round Class V cavities (enamel and dentin margins) were prepared. A total-etch (N-Bond total etch) (Ivoclar Vivadent) and self-etching ...

This study evaluated the effect of multiple consecutive adhesive resin coatings of adhesive bonded to human dentin on nanoleakage and resin-dentin bond strength. Resin bonded dentin specimens were prepared using a total-etch adhesive (One-Step Plus) applied as multiple consecutive coating, or using two self-etch adhesive systems (iBond or Fluoro Bond). For the total-etch adhesive, resin applica...

Background: Adhesive procedures have become an integral part of today’s restorative dental procedures. This study was carried out to evaluate the effect of contaminants such as saliva, blood, and hemostatic agents on the shear bond strength of a self-etch adhesive system Clearfil SE Bond, one-step, self-etch adhesive system AdperTM Easy One and a total-etch adhesive system AdperTM Single Bond 2...
