Evaluation of two different self-disinfection alginate impression material.

Objective: This study was conducted to evaluate the antimicrobial efficacy and mechanical properties of two experimental self-disinfecting alginate preparations utilising two different antimicrobial agents; povidone-iodine and silver nanoparticles.

Methods: Alginate moulds were assigned into three groups. Additives-free control group, povidone-iodine-containing group, and silver nanoparticle-containing group.

Wollastonite as filler of an experimental dental adhesive.

Objective: The aim of this study was to formulate experimental dental adhesives with wollastonite and evaluate the physical, chemical, and bioactivity properties of the resins.

Methods: Wollastonite was characterized by Fourier transform infrared spectroscopy, X-ray and laser diffraction analyses, and scanning electronic microscopy. An experimental adhesive resin was formulated, and wollastonite was used as filler at 0 (control group), 0.
