Abstract

This 3 phase study examined (1) the effect of microwave irradiation on the adhesion and (2) biofilm formation of 4 candidal species on heat polymerized polymethyl methacrylate (PMMA) specimens. Lastly, (3) the flexural strength of heat polymerized PMMA was tested.C. albicans (ATCC 10231), C. glabrata (ATCC 22019), C. krusei (ATCC 6258) and C. parapsilosis (ATCC 90030) were used. The flexural strength of the PMMA resin after microwave irradiation was tested in accordance with ISO 20795-1 specifications. A one-way ANOVA statistical analysis was used for all the results.The maximum effect of 94% to 98% reduction in adhesion and biofilm counts was seen with microwave irradiation at 850 W and 1000 W for 120 sec. There was no significant difference between the control and irradiated specimens in terms of flexural strength. Reduction of candida adhesion and biofilm on PMMA resin can be achieved with microwave irradiation.
