Concrete-timber composite floor is a construction technique combining two materials, concrete and timber, connected together using some form of interlayer shear connectors either positioned discretely or continuously along the span of the floor. The interlayer connections provide the desired composite action, where the degree of this composite action is governed by the types of connection syste...
The aim of the study was to determine the static load-bearing capacity of fractured incisal teeth restored with the conventional adhesive-composite technique or by using fiber reinforced composites (FRC). Upper incisal teeth were prepared by cutting the incisal part of the crown horizontally. Restorations were made by three techniques. Group A (control group) was restored by reattaching the ori...
Background and Aims: Dentin contamination with different materials used in pediatrics is effective on the bond strength of adhesives to primary teeth. Therefore, the purpose of this in vitro study was to evaluate the effect of zinc oxide-eugenol and formocresol on the shear bond strength (SBS) of resin composite to the dentin in primary teeth. Materials and Methods: A total of 72 extracted seco...
The purpose of this study was to evaluate the effect of polishing procedures on the color stability of different types of composites after aging. Forty disk-shaped specimens (Ø10×2 mm) were prepared for each composite resin type (an ormocer, a packable, a nanohybrid, and a microhybrid) for a total of 160 specimens. Each composite group was divided into four subgroups according to polishing meth...
We developed a composite compliance index as the sum of the compliance scores for interdialytic weight gain (IDWG), pre-dialysis serum potassium and phosphorus concentrations (each scored from zero to 3, with 3 indicating the poorest compliance), and skipping hemodialysis sessions (scored from zero to 9, with 9 indicating the poorest compliance). We used this composite score to prospectively ev...
