Fig. (1). Antimicrobial effect of silver ions.

a) Inhibition of S. mutans growth in the presence of silver ions dissolved in suspension. b) Growth inhibitory effect of silver ions in agar diffusion assay at various concentrations. c) Close-up photograph of an overlay assay demonstrating the inhibitory effect of Kerr sealer impregnated with 20% silver ions compared to Kerr sealer alone. * Denotes a significant difference in the growth inhibition (P < 0.05), see text for details. n = 4.
