This paper reflects on the state of the art of self-etch adhesives anno 2010. After presenting the general characteristics of self-etch adhesives, the major shortcomings of the most simple-to-use one-step (self-etch) adhesives are addressed. Special attention is devoted to the AD-concept and the benefit of chemical interfacial interaction with regard to bond durability. Finally, issues like the...

At Skyworks Solutions throughput of the back side through-wafer via etch process was low because of a high rework rate. The high rework rate was due to an organic residue blocking the etch. A process was first developed to remove the residue and then integrated into the via etch process. The optimized via etch process resulted in a reduction in reworks and a significant increase in process thro...

We show strong changes in chemical etching of phosphorus-doped fiber cores due to hydrogen loading and subsequent UV-irradiation using an atomic force microscope. The etch rate of the fiber core in a low concentration hydrofluoric acid solution (HF) is decreasing after hydrogen loading by as much as 30%. In contrast, UV-irradiation of the hydrogenated fiber increases the core etch rate to value...

The etching of silicon in remote microwave discharges fed with NF3 /O2 has been investigated. In situ ellipsometry and x-ray photoelectron spectroscopy ~XPS! were used to monitor surface effects, while mass spectrometry was used to monitor the gas phase dynamics. Varying the microwave power from 600 to 1400 W has little effect, due to the near complete dissociation of the NF3, even at lower pow...

This study determined the effect of cleansing solutions on microtensile bond strengths of self-etch adhesives to saliva-contaminated dentin. Seventy five human molars were ground flat to expose mid-depth dentin, and randomly assigned to 5 groups (n=15): no contamination, saliva contamination without cleansing, saliva and cleansing with water, saliva and cleansing with 2% chlorhexidine, and sali...

BACKGROUND Patient demand for tooth colored restorations and desire for minimally invasive restorations have made composites an indispensable part of the restorative process. An important factor affecting the intra-oral performance of composite restorations is bonding. MATERIAL AND METHODS Ninty six freshly extracted molar teeth were collected and occlusal 3mm is removed using a diamond disc ...

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...

—We present ETCH, efficient channel hopping based MAC-layer protocols for communication rendezvous in Dynamic Spectrum Access (DSA) networks. Compared to the existing solutions, ETCH fully utilizes spectrum diversity in communication rendezvous by allowing all the rendezvous channels to be utilized at the same time. We propose two protocols, SYNC-ETCH, which is a synchronous protocol assuming D...

OBJECTIVES The objective of this randomized controlled clinical trial was to evaluate the 8-year clinical performance of a mild 2-step self-etch adhesive in non-carious Class-V lesions with and without prior selective phosphoric acid-etching of the enamel cavity margins. METHODS A total of 100 non-carious Class-V lesions in 29 patients were restored with Clearfil AP-X (Kuraray). The composite...

Amaç: Bu çalışmanın amacı; All Bond Universal adeziv sisteminin farklı uygulama teknikleriyle (total-etch, aktif self-etch, pasif self-etch) ajanlarla remineralize edilmiş (Remin Pro veya MI Paste Plus) mine yüzeyine uygulandığında makaslama bağlanma dayanımını ve yüzeylerde oluşan farklılıkları SEM ile değerlendirmektir.
