This study evaluated the clinical, radiographic, and histologic response to the composite use of Bio-Oss porous bone mineral and autogenous bone in combination with a Bio-Gide bilayer collagen membrane to achieve regeneration when treating human periodontal bone defects. Preoperative recordings for four treatment areas included radiographs, clinical probing depths, and attachment levels; these ...

In this study multifunctional bio-based cotton composites were fabricated. The characterization of fabricated investigated by using Fourier Transform Infrared Spectroscopy (FTIR), Thermo Gravimetric Analysis (TGA) and Scanning Electron Microscopy (SEM). And also antibacterial test dye adsorption properties investigated. effects contact time, pH, temperature, ionic strength on removal remazol bl...

AIM To evaluate the capability to reinforce tooth structure and sealing ability of temporary filling materials in premolars with MOD cavities. The hypothesis is that temporary filling materials can concomitantly prevent microleakage and increase fracture resistance. MATERIALS AND METHODS Premolars received root canal treatment and MOD cavities. Cavities were restored with non- eugenol cement ...

A new bio-prosthetic valved conduit (Bio-Valsalva) has recently been introduced into surgical practice in order to offer a valid option for elderly patients undergoing composite aortic root replacement. The conduit is made up of a stentless porcine valve (elan valve) pre-sewn inside a triple layer Valsalva prosthesis and it is entirely preserved in a glutaraldehyde solution. In our Department, ...

Biological materials with hierarchically laminated structures usually exhibit a good synergy between strength and fracture toughness. Here, we show that a bio-inspired (polyelectrolyte (PE)/TiO2)4 nanolayered composite with a thickness ratio of TiO2 and amorphous PE layers of about 1.1 has been prepared successfully on Si substrates by layer-by-layer self-assembly and chemical bath deposition m...

We report a fully integrated, portable, battery-operated electronic nose system comprising a bio-inspired two-layer multiple-walled carbon nanotube (MWNT)-polymer composite sensor array, a bio-inspired fast-adaptive readout circuit, and a microprocessor embedded with a pattern recognition algorithm. The two-layer MWNT-polymer composite sensor is simple to operate, and the membrane quality can b...
