Bioinspired artificial surfaces with tailored adhesive properties have attracted significant interest. While fibrillar adhesive pads mimicking gecko feet are optimized for strong reversible adhesion, monolithic microsphere arrays mimicking the slippery zone of the pitchers of carnivorous plants of the genus Nepenthes show anti-adhesive properties even against tacky counterpart surfaces. In cont...

Introduction: In order to determine the real efficacy and durability of polymeric dental adhesives, thorough clinical testing is necessary. However, in practice, long-term clinical testing is expensive and commercial adhesive materials are constantly undergoing change so that the clinical testing necessary to evaluate their long-term properties and success rates (typically four years) becomes i...

commercial etch-and-rinse adhesive systems, with and without silane, on their degree of conversion (DC) (%) and microtensile bond strength (μTBS). The NbG micro-filler was added to two etch-and-rinse adhesive systems: One Step (OS) and Prime & Bond (PB) at 40% concentration. The following groups were formed: control without glass addition OS; addition of unsilanized NbG (OSNbG); addition of sil...

Insect tarsal adhesive structures secrete a thin layer of fluid into the contact area. It was previously reported that the presence of this fluid significantly increases adhesion on various substrata. Previous data obtained from representatives of different insect groups suggest a difference not only in the chemical composition of the fluid, but also in its physical properties. In the present s...

The concept of typed attributed graph transformation is most significant for modeling and meta modeling in software engineering and visual languages. In this thesis we introduce adhesive high-level replacement categories and systems as a new categorical framework for graph transformation in a broad sense. It combines the well-known concept of high-level replacement (HLR) systems with the new co...

The aim of this study was to evaluate the effect of desensitizing agents on the bond strength of different adhesive systems condition and rinse and self-etching to dentin through microshear. Sixty dentin fragments were used, obtained from the buccal and lingual surfaces of molars third molars, which were distributed in groups (n = 12) according to desensitizing treatment (control no treatment; ...

Aim. To evaluate the effect of cigarette smoke on water sorption and solubility of four adhesive systems. Materials and Methods. Sixteen disks of each adhesive system were prepared (Adper Scotchbond Multipurpose Adhesive (SA); Adper Scotchbond Multipurpose Adhesive System (Adhesive + Primer) (SAP); Adper Single Bond Plus (SB); Adper Easy One (EO)). Specimens were desiccated until a constant mas...

The objective of this in vitro study was to evaluate the effect of three surface treatments and two adhesive systems on the shear bond strength of old and freshly placed amalgam. The results suggested that the intact amalgam showed a significantly higher strength than repaired groups and the strongest repaired specimens were made when the amalgam surfaces were roughened with a diamond bur or mi...

This study aimed to evaluate the effect of adhesive application method on durability enamel bond and thickness layer. A new-generation two-step universal system, G2-Bond Universal, two conventional systems were utilized. The shear strength bovine was measured after thermal cycling in both etch-and-rinse self-etch modes. Fifteen specimens divided into three groups as follows: Group I, wherein a ...
