Comparison between Polyacid-Modified Composite Resin and Conventional Composite Resin used for Primary Molars Restoration

Ten recently extracted primary molars, were used in this study for the measurement of the shear bond strength. Occlusal enamel was ground, leaving a flat dentin surface, on which a cylindrical specimen of each of the two tested materials was applied and light-cured according to the manufacturer’s instructions. Specimens were then mounted in self-cure acrylic resin. Ten specimens were used for the measurement of the compressive strength. The specimens were prepared in a special-cylindrical mold, then light-cured according to the manufacturer’s instructions. The compressive and shear bond strength of each specimen was measured using a Universal Testing Machine.Ten specimens of each of the two resin materials were used to measure the abrasion resistance. The test was performed by means of a toothbrushing machine and abrasive dentifrice slurry. The specimens were weighed before and after the test. Weight loss of the specimens were calculated after the test and reported as percent weight loss. Regarding microleakage test, Class V cavities were prepared in the buccal surface of 36 exfoliated or extracted human primary molars.

A Review: Fiber Reinforced Polymer Composite Helical Springs

NanotechnologyAbstractIntroductionIn order to successfully reduce the weight of a helical spring it is possible to optimize the material parameters or to use alternative advanced materials instead of conventional engineering ones. Springs are used for vibration damping in mechanical systems and are generally made of steel. As an alternative to material of steel springs in the scope of the study, mechanical behaviors of fiber reinforced polymer (FRP) composite helical springs have been investigated. The FRP composite material has made it possible to reduce the weight of helical spring without any reduction on load carrying capacity. Due to increasing competition and innovation in recent decades, vehicle industries show interest in replacing conventional steel spring with FRP composite helical spring which has advantages such as higher strength to weight ratio, higher stiffness, high impact energy absorption and lesser stresses. The study gives the brief look on the suitability of FRP composite helical springs on related mechanical systems. The objective of the present work is evaluation of the design, analysis and fabrication of FRP composite helical springs.
