Abstract
Dental composites often act as the barrier between the inner surface of an imperfect tooth and the bacteria found within the human mouth. The bacteria can lead to cavities and other infections in the gums if the dental composite is not completely sealed to a tooth, which is frequently the case. This research is aimed at evaluating if dental composites containing silver nanoparticles could decrease the risk of infection due to the antimicrobial effects of silver. Several different sizes and shapes of silver nanoparticles were combined with dental composites in order to synthesize a composite that is both antimicrobial and the color of human teeth. The effects of particle size and surface area on the antimicrobial response to Pseudomonas aeruginosa were evaluated with contact angle analysis and atomic force microscopy. A significant antimicrobial response with the addition of silver nanoparticles was found. In addition, the synthesis of new silver nanoparticles which may enhance antimicrobial activity is presented.
