Omnichroma is a smart monochromatic material and believed to attain the shade of surrounding tooth structure in which it placed. However, color stability this unknown. Therefore, study was conducted evaluate effect different pH beverages on composite its comparison with micro-hybrid resin. Sixty extracted human maxillary premolars shades, viz. A2, A3, B2 B3, were selected equal numbers. A Class...

Abstract A study of smart functionally graded (FG) beams made carbon nanotube (CNT) reinforced composites combined with piezoelectric materials is presented. The material parameters the composite are assumed to vary along their thickness following extended rule mixture. finite element (FE) model was developed for FG nanotube-reinforced beam materials. This tested against previously published st...

The creation of multi-stimuli-sensitive composite polymer–inorganic materials is a practical scientific task. combination photoactive magneto-piezoelectric nanomaterials and ferroelectric polymers offers new properties that can help solve environmental energy problems. Using the doctor blade casting method with thermally induced phase separation (TIPS) technique, we synthesized hybrid nanocompo...

BACKGROUND Both balanced crystalloids and saline are used for intravenous fluid administration in critically ill adults, but it is not known which results in better clinical outcomes. METHODS In a pragmatic, cluster-randomized, multiple-crossover trial conducted in five intensive care units at an academic center, we assigned 15,802 adults to receive saline (0.9% sodium chloride) or balanced c...

This study was conducted to evaluate the compressive strength, compressive fatigue limit and the amount of fluoride released from the Smart Dentin Replacement SDR TM restorative material in comparison to another fluoride released from hybrid resin composite material Tetric N Ceram. A total of eighty (80) specimens were used in this study, where forty (40) specimens were used to evaluate the com...
