Objective: this study sought to evaluate the effect of isobornyl methacrylate (IBOMA) as a diluent monomer on the physicochemical properties of experimental flowable resin composites.
Methodology: the organic resin matrix of a modal flowable resin composite was formulated with 50 wt.% of bisphenol-A-glycidyl methacrylate (Bis-GMA) and 50 wt.
The aim of this study was to assess the effect of adding arginine at different concentrations to commercial and experimental orthodontic resins on shear bond strength (SBS), as well as on the antimicrobial activity of arginine against S. mutans. Metal brackets were bonded onto the surface of 120 bovine incisors using Transbond, OrthoCem, and an experimental resin (ER), adding 0, 2.

- A study investigated the properties of acrylamides in self-etching primers, focusing on their stability at acidic pH and compatibility with total etch adhesives.
- The experimental materials included various acidic primers and adhesives, all designed to bond a commercial dental composite to human dentin while measuring bond strength, flexural strength, viscosity, and other characteristics.
- Results indicated that HEMA-based materials displayed lower contact angles and higher water sorption compared to DEBAAP, with some performance metrics showing statistical significance, suggesting differences in their bonding abilities.
This laboratory study aimed to evaluate the effects of zirconium dioxide (ZrO2) slurry surface treatment on the bond strength of ultratranslucent zirconia to resin cement using different ceramic primers. The surface morphology was evaluated by scanning electron microscopy (SEM) and atomic force microscopy (AFM), and the interface was evaluated by SEM. Additionally, the phase composition was analyzed by X-ray diffraction (XRD).
