Denture hygiene is an important factor in the treatment of denture stomatitis. Sterilization of dentures by microwaves has been recommended, but using specialized equipment not available to the average person. This study tests the effect of microwaving on the dimensional stability of dentures (in an unmodified domestic microwave oven). After microwaving (10 mins at 604 W) some measurements showed significant contraction or expansion but reduced exposure (6 mins at 331 W) caused much smaller changes. The dimensional changes are inexplicable but at lower radiation are considered to be harmless.
