摘要: Complete dentures acts as a reservoir for microbial colonization, which may lead to systemic infections. Microwave irradiation has been used an efficient method of denture disinfection. Even though current methods eliminate denture-base microorganisms, recurrence rate stomatitis (DS) is still observed among denture-wearing patients. It was hypothesized that microwave disinfection kills microorganisms but do not remove dead bacteria from the surface. To test this hypothesis, biofilm found in 10 patients with DS evaluated. In addition, effects plus brushing (MW+B) on and combination cleanser (MW+DC+B) removal denture-accumulating were investigated. Microbiological data analyzed statistically by nonparametric analysis (Friedman/Wilcoxon, α=0.05). MW+B MW+DC+B effective reducing (99.2% 99.5% respectively), without significant difference between them (p=0.553). However, it complete surface only possible when all regimens combined (MW+DC+B). soaking effectively disinfected removed biofilm.
