Abstract
Infection control of dental impression has become an important issue for dental technician. Dental impressions may be contaminated with microorganisms from patient’s saliva and blood. A microwave treatment can be used as a method to disinfect dental prosthesis. The aim of this study was to evaluate the physical properties of polyvinyl siloxane impression materials after microwave treatment. We performed microwave treatments using electrical microwave oven with and without hydrogen peroxide. Detail reproduction, compatibility with gypsum, linear dimensional change, contact angle, strain-in-compression and elastic recovery were evaluated before and after microwave treatment. Experimental groups were composed with 6 groups by irradiated conditions such as 1, 2 and 3 minutes with and without hydrogen peroxide solution of 3 wt% in microwave chamber. Control group was no treatment group. The results of all tests showed that there were no significant differences between before and after microwave treatment(p>0.05). So we recommend that the microwave treatments for polyvinyl siloxane impressions would be used in clinical field.
