Faculty of Dentistry, Department of Periodontology, Marmara University;
Dental ultrasonic scalers are commonly employed in periodontal treatment; however, their ability to roughen tooth surfaces is a worry since roughness may increase plaque production, a key cause of periodontal disease. This research studied the influence of a piezoelectric ultrasonic scaler on the roughness of two distinct flowable composite filling materials. To do this, 10 disc-shaped samples were generated from each of the two flowable composite materials.

The potential of epoxy-graphene oxide (GO) nanocomposites to improve the mechanical characteristics of conventional epoxy resins is causing them to gain prominence. This makes them appropriate for advanced engineering applications, including structural materials, automotive, and aerospace. This study aimed to develop an epoxy/GO composite with improved mechanical properties through synthesizing epoxy/GO samples with varying GO content (from 0.

Introduction: Previous studies have shown () esterase is a key mediator of dental composite biodegradation, which can contribute to recurrent caries. This study is to investigate the inhibitory effects of a novel Chemically-Modified-Curcumin (CMC 2.24) on esterase activities and related dental material biodegradation.

Wind energy offers a low emission source of energy while also being among the cheapest forms of electricity generation in the United States. While most materials in a wind turbine can be recycled at the end of their life, large composite blades are often treated as waste, leading to potential strains on regional landfills, a loss of durable materials, and forfeiture of embodied energy. Numerous approaches exist for recycling composite wind blades at various levels of technological and commercial maturity.

Herein, electrochemical sensing of paracetamol in polluted water was achieved using facile-synthesized tungsten oxide nanoparticles. Ion exchange resin has been used as a sustainable preparation route, while the prepared nanoparticles have been characterized by XRD and SEM analyses. Orthorhombic WO·HO nano-plates have been synthesized a facile preparation method, where the crystal size has been calculated as 25-33 nm, and these results were used to create a 3D model of the prepared WO·HO nano-plates.
