Effect of SSD at lower concentrations on the DNA content of the three strains in mature mixed bacterial voice prosthesis biofilms. A Effect of SSD on Staphylococcus aureus in the biofilms; B Effect of SSD on Streptococcus faecalis in the biofilms; C Effect of SSD on Candida albicans in the biofilms. The results are expressed as the mean ± SD. *P < 0.05 indicates a significant difference compared with the negative control group
