BACKGROUND Composite aortic root replacement is accepted treatment for aneurysms of the ascending aorta involving the root with aortic valve regurgitation, but controversy continues regarding the best technique of operation. We excise the aneurysm, implant a composite valve graft, directly attach the coronary arteries to the aortic graft, and make the distal anastomosis to the divided aorta. ...

Anterior diastema may compromise the harmony of a patient’s smile. Among the suggested options for diastema closure such as orthodontics, restorative dentistry, and prosthodontics, it is appreciable that restorative approach is the simplest, fastest, most predictable, and lowest solution. But, handling composite freehand requires skillful practice and it may be considered as a disadvantage to s...

Manipulation of inorganic materials with organic macromolecules enables organisms to create biominerals such as bones and seashells, where occlusion of biomacromolecules within individual crystals generates superior mechanical properties. Current understanding of this process largely comes from studying the entrapment of micron-size particles in cooling melts. Here, by investigating micelle inc...

Dental adhesives used to bond composite resins to tooth structure have evolved over the last several decades. The earliest bonding systems required an acid-etch technique and were only compatible with enamel, and the challenge has always been to predictably bond to enamel and dentin simultaneously. There can be confusion as to what bonding agents are being described, because there are a number ...

The activation gap Delta of the fractional quantum Hall states at constant fillings nu=2/3 and 2/5 has been measured as a function of the perpendicular magnetic field B. A linear dependence of Delta on B is observed while approaching the spin-polarization transition. This feature allows a direct measurement of the g factor of composite fermions which appears to be heavily renormalized by intera...

This study demonstrates a versatile and fast method for patterning three-dimensional (3D) monolithic microstructures made of multiple (up to 24 demonstrated) types of materials, all spatially aligned, inside a microchannel. This technique uses confocal scanning or conventional fluorescence microscopy to polymerize selected regions of a photocurable material, and microfluidics to automate the de...

Mastering anterior direct composite restorations is a necessity for the contemporary clinician who appreciates and understands the art and science of cosmetic dentistry. In the esthetic zone, composite bonding procedures are considered the most conservative and least invasive technique to return missing, diseased, and unsightly tooth structure to enhanced color, form, and function. Composites' ...
