| Summary: | Aims: To evaluate the best microwave power and the proper time that disinfect acrylic resin denture base material. Methodology: Fifty five samples were prepared from heat cured acrylic resin(10 mm x 10 mm x 2 mm) then immersed in glass flask containing brain heart broth and inculated with swabs from patients wearing complete denture divided into: negative control group (untreated), positive control group immersed in 0.02% sodium hypochlorite for 8 hours, and nine groups of different microwave disinfection settings (different powers and times),then immersed in sterile BHI broth individually and diluted up to 10-4 and 0.01ml plated in blood agar and Sabouraud's dextrose agar and CFU/ml were collected. Results: analysis of the data showed a significant
difference between tested groups. Conclusions: microwave disinfection at 900 W and 540W for 3 minutes showed both antifungal and antibacterial effect. |
