The effect of silver nanoparticles incorporation in the self-etch adhesive system on its antibacterial activity and degree of conversion: an in-vitro study

About this activity

Dental resin composite is a widely used restorative material that has superior aesthetic properties and strong bonding ability to the tooth structure in comparison to other restorative materials like amalgam. Silver is an antimicrobial agent that has broad spectrum activity against gram positive and gram negative bacterian Objectives Course Objective Despite of the recent advances in the adhesive dentistry, high possibility of microbial biofilm development at the resin restoration surfaces may lead to marginal gaps and recurrent caries. Degree of conversion of the dental adhesive represents a relative assessment to its quality, and a direct correlation with its mechanical behavior. This. Minimum Inhibitory Concentration of the self-etch adhesive system incorporated with nanosilver powder and solution against. The results showed that silver nanoparticles incorporation (powder or ethanol based at 12.5 µg/ml concentration) significantly increased the antibacterial efficacy of the self-etch adhesive against. The antibacterial efficacy of the adhesive system can be greatly potentiated with the addition of silver nanoparticles (12µg/mL concentration) especially the nanosilver powder. Incorporation of the antibacterial nanosilver powder in the adhesive system didn’t compromise the degree of conversion of the adhesive resin.
