Purpose: In this study, the shear bond strengths (SBS) of luting cements to fixed superstructure metal surfaces under various seating forces were investigated.
Materials And Methods: Seven different cements [Polycarboxylate (PCC), Glass-Ionomer (GIC), Zinc phospahate (ZPC), Self-adhesive resin (RXU), Resin (C&B), and Temporary cements ((RXT) and (TCS))] were bonded to a total number of 224 square blocks (5×5×3 mm) made of one pure metal [Titanium (CP Ti) and two metal alloys [Gold-Platinum (Au-Pt) and Cobalt-Chrome (Co-Cr)] under 10 N and 50 N seating forces. SBS values were determined and data were analyzed with 3-way ANOVA.
Background: Biopolymeric nanoparticles comprising chitosan-alginate have attracted interest in drug delivery due to their protective nature, biocompatibility, biodegradability and hydrophilicity.
Objective: The present study was designed to encapsulate levofloxacin in chitosan-alginate hybrid gel for controlled release and to evaluate the effect of divalent alkaline earth metal ions (Mg2+, Ca2+, Sr2+, Ba2+) on encapsulation efficiency and drug release kinetics considering their role in polyelectrolyte gelation method.
Method: Divalent metal ions control the rigidity and elasticity of the hydrogels and have the ability to change the shape and size of nanostructure formed by chitosan-alginate.
