Fig. 2From: Antibacterial activity and biocompatibility of silver coating via aerosol deposition on titanium and zirconia surfacesAbsorbance of the crystal violet solution on zirconia surfaces incubated with A S. gordonii for 24 h, B F. nucleatum for 72 h and C P. gingivalis for 48 h. The bars and intervals represent the mean absorbance values and standard deviations, respectively (n = 3; *p < 0.05)Back to article page
