Comparison of Surface Roughness Area (Sa) among mono-species biofilms of C. albicans treated with the substances (n = 6/group). Asterisk shows that growth control presented significantly higher surface roughness compared to other groups (p < 0.05). This is suggestive that chlorhexidine and red propolis extract removed most of biofilm, similarly to clean (baseline) specimens
