Effect of four methods (UVC, ozone, solution, and spray) used for disinfection of A-silicones (Panasil Putty Soft, Panasil monophase Medium, and Panasil initial contact Light) contaminated with oral pathogens (S. aureus, P. aeruginosa, and C. albicans); Control material was contaminated but not disinfected; ns—not significant (p > 0.05); for all other comparisons between the study (disinfected) groups and the control (non-disinfected) group, differences were significant (p < 0.05); detailed results of statistical analysis are included in Table 3. S. aureus—Staphylococcus aureus; P. aeruginosa—Pseudomonas aeruginosa; C. albicans—Candida albicans; UVC—ultraviolet C.
