State of the art of self-etch adhesives

Relationship between bond-strength tests and clinical outcomes

Nanotechnology is a broad interdisciplinary area of research, development, and industrial activity that has been growing rapidly worldwide for the past decade. More ambitious uses of nanoparticles are bioremediation of contaminated environments, controlled release of fragrances, biocides, and antifungals on textiles. Silica nanocomposites have received much attention because of its thermal degradation behavior and applications in chromatography, medicine, optics, etc. Nanobiotech takes agriculture from the battleground of genetically modified organisms to the brave new world of atomically modified organisms where rice has been modified atomically. Silica has been widely applied in various industries. Application of gold-coated silica has been used in the treatment for benign and malignant tumor. Surface-modified hydrophobic as well as lipophilic nanosilica could be effectively used as novel drugs for treatment of chicken malaria and nuclear polyhedrosis virus (BmNPV), a scourge in silkworm industry. Here, the authors attempt to provide a review to explain the impact of nanosilica on basic biology, medicine, agro-nanoproducts, and use of amorphous nanosilica as biopesticide.

The role of etching in bonding to enamel: A comparison of self-etching and etch-and-rinse adhesive systems

A laboratory study was conducted to determine the shear bond strength to enamel and dentin using the Scotchbond Multi-Purpose dental adhesive system. High shear bond strengths of P50 composite to both human enamel (26.8 +/- 5.2 MPa) and bovine enamel (24.8 +/- 4.1 MPa) were found when the system was used according to manufacturer's directions. The mean bond strength for human dentin (25.5 +/- 7.5 MPa) was also similar to that found for bovine dentin (23.4 +/- 4.9 MPa). Variations in the recommended application technique were examined on bovine dentin. Extreme air drying of the primer slightly reduced the mean shear bond strength (19.7 +/- 6.4 MPa), while a significant reduction was observed when the adhesive resin was aggressively air-thinned (10.1 +/- 6.6 Mpa).

Shear bond strength of composite to enamel and dentin using Scotchbond Multi-Purpose.

Influence of different etching modes on bond strength and fatigue strength to dentin using universal adhesive systems.

Bond strength of self-etch adhesives to pre-etched enamel.

Clinical Relevance Traditionally, etch-and-rinse adhesive systems have used phosphoric acid to condition enamel surfaces and successfully create a strong, durable bond to resin-based materials. Newer adhesive systems now use acid monomers to bond resin materials to both enamel and dentin. These newer adhesives do not provide the same degree of bonding to enamel as etch-and-rinse systems, and extending the application time does not improve their performance.
