Fig. 4From: “Inhibitory effect of Brazilian red propolis on Candida biofilms developed on titanium surfaces”Comparison of Surface Roughness Area (Sa) among co-culture biofilms treated with the substances (n = 6/group). Asterisks show that growth control and red propolis extract presented significantly higher surface roughness compared to other groups (p < 0.05). This is suggestive that chlorhexidine removed most of biofilm, similarly to clean (baseline) specimensBack to article page
