Non-Thermal O2 Plasma Efficacy on C. albicans and Its Effect on Denture Base Resin Color

Denture stomatitis is a disease involving C. albicans, which can affect elderly and immuno-compromised people. To avoid any recurrence of this pathology, it necessary to treat patients regularly disinfect dentures. However, the denture cleansers’ efficacy not optimal often leads adverse color effects on base resins. The aim study was investigate low-pressure non-thermal O2 plasma (NTP) treatment albicans seeded ProBase®Hot resin (Ivoclar Vivadent). viability reduction assessed by colony forming units (CFU) analysis scanning electron microscopy (SEM). effect repeated treatments evaluated spectrophotometry. samples were placed in sealed bag generated conditions. results showed that 120-min NTP led 6-log (p < 0.05) yeasts’ major alterations observed SEM. Furthermore, significant slight changes (∆E00 = 1.33) noted only after six 0.05). aesthetic preserved, as perceptible remained below acceptability threshold 4).
