study on the effect of chemical disinfectants on acrylic resin cured by two different techniques

ABSTRACT

New requirements for infection control in dentistry is of an utmost need in which dentures must be handled before delivery to patients. This study was undertaken in attempt to study the changes in some physical and mechanical properties of heat cured acrylic resin cured by two different techniques, the conventional water bath and microwave energy after disinfection by immersion for 7 days in 0.5% chlorhexidine, 2% gluteraldehyde, 0.55 sodium hypochloride and 70% ethanol. The results showed that only ethanol is not suitable to be used for disinfection of heat cured acrylic resin cured by either method:
