Article Synopsis
  • This study introduces an inexpensive plasma device that employs a 3D-printed design using a parallel-plate dielectric barrier discharge with a metallic mesh electrode.
  • The device operates on atmospheric air without requiring additional gas supply and significantly modifies the surface composition of polyethylene, reducing carbon levels and increasing oxygen after treatment.
  • It effectively reduces microbial load by over 99% within 1 to 10 minutes while maintaining Vero cell viability between 91% and 96%, indicating its potential for material surface modifications and infection control applications.

Despite the excellent properties of silicone endotracheal prostheses, their main limitation is the formation of a polymicrobial biofilm on their surfaces. It can cause local inflammation, interfering with the local healing process and leading to further complications in the clinical scenario. The present study evaluated the inhibitory effect of cold atmospheric plasma (CAP) on multispecies biofilms grown on the silicone protheses' surfaces.

The failure of endodontic treatment is frequently associated with the presence of remaining microorganisms, mainly due to the difficulty of eliminating the biofilm and the limitation of conventional irrigation solutions. Non-thermal atmospheric pressure plasma (NTPP) has been suggested for many applications in the medical field and can be applied directly to biological surfaces or indirectly through activated liquids. This literature review aims to evaluate the potential of NTPP application in Endodontics.

Soft reliner and glaze are materials used over full or partial dental prosthesis to prevent excessive pressure on the supporting tissues. They are also indicated as supportive treatment for dental stomatitis, especially when modified by the addition of medications. The objective of the work was to evaluate the antimicrobial effect of silver-coated silica nanoparticles in a glaze and a soft reliner.
