The purpose of this study was to examine the anti-oral microorganism effects of fluorine and/or silver ions implanted into acrylic resin (PMMA) using plasma-based ion implantation (PBII) with argon gas. The experimental PMMA specimens were implanted with F and Ag ions alone or simultaneously by the PBII method using Ar or Ar/F gases and Ag mesh. The surface characteristics were evaluated by X-ray photoelectron spectroscopy (XPS), contact angle measurements, and atomic force microscopy (AFM).

- Prevention is crucial in pediatric dentistry, and pit and fissure sealants help control early dental lesions before they turn into cavities.
- Research indicates that glass-ionomer cement (GIC) sealants may outperform resin-based options due to their fluoride release and strong adhesion, although GIC has lower strength and is prone to fracture.
- The study introduces an apatite-ionomer cement (AIC) that blends hydroxyapatite with GIC to enhance its strength and functional properties, making it a promising material for preventing tooth decay and aiding remineralization.
In this study, we aimed to evaluate the effect of the addition of powdery cellulose nanofibers (CNFs) on the mechanical properties of glass ionomer cement (GIC) without negatively affecting its chemical properties. Commercial GIC was reinforced with powdery CNFs (2-8 wt.%) and characterized in terms of flexural strength, compressive strength, diametral tensile strength, and fluoride-ion release properties.
