Summary
Silver nanoparticles (AgNP) can enhance denture soft lining materials, preventing fungal and bacterial colonization. This study details a method for incorporating AgNPs into silicone soft liners to improve oral hygiene and prevent mucosal infections.
Area of Science:
- Biomaterials Science
- Dental Materials
- Nanotechnology
Background:
- Denture soft lining materials are susceptible to colonization by fungi and bacteria, leading to mucosal infections.
- Standard disinfectants are often insufficient for maintaining proper hygiene due to microbial penetration into soft liners.
- Silver nanoparticles (AgNP) offer a promising antimicrobial solution for modifying biomaterials.
Purpose of the Study:
- To develop and present a procedure for modifying two-component silicone soft lining materials with silver nanoparticles (AgNP).
- To investigate the feasibility of incorporating AgNPs into silicone soft liners to enhance their antimicrobial properties.
- To establish an effective method for creating AgNP-modified silicone composites for improved denture hygiene.
Main Methods:
- Solubility tests were conducted on silicone soft liner components to select an appropriate solvent.
- A solvent was identified as a suitable dispersion medium for AgNPs and silicone components.
- An effective solvent evaporation technique was developed to create AgNP-modified silicone materials with varying AgNP concentrations (10-200 ppm).
- Scanning Electron Microscopy (SEM) was used to confirm the successful incorporation of AgNPs into the cured composite samples.
Main Results:
- A solvent was successfully identified and utilized as a dispersion medium for both AgNPs and silicone soft liner components.
- An effective method for solvent evaporation was established, allowing for the creation of modified material components.
- Silicone composites with AgNP concentrations ranging from 10 to 200 ppm were successfully fabricated.
- SEM analysis confirmed the effectiveness of the procedure in incorporating AgNPs into the silicone matrix.
Conclusions:
- The presented procedure effectively modifies two-component silicone soft lining materials with silver nanoparticles (AgNP).
- This AgNP modification holds potential for improving the antimicrobial properties of denture soft liners.
- The developed method offers a promising approach to enhance oral hygiene and combat infections associated with soft lining colonization.
