Abstract
Evaluate the antibacterial activity, elemental composition and bond strength test of silver nanoparticles incorporated in dentin adhesive aterial.
Materials and Methods: Adper scotch bond multipurpose adhesive was the
material of choice where different concentrations of spherical silver
nanoparticles having a size of 4 nm and ranging from 2.5, 5 and 10
were used to modify it. Twenty sound non-carious molars were assigned randomly for the micro-shear bond strength test. Modes of failure
were distinguished by scanning the fractured specimens with an
environmental scanning electron microscope. For assessment of antibacterial activity, direct contact test was performed and the viability of the bacteria was investigated using the fluorescent microscope. Finally, the tooth adhesive interface was analyzed with the EDX machine for elemental
composition analysis. Results: The bond strength of the material and the
modes of failure did not show any statistical significant difference between the control and the experimental material. Adding silver nanoparticles to the resin adhesive altered its biological activity rendering it a material expressing antibacterial action which is directly proportional to the concentration. For viability.
