Abstract

Dental impressions need to be washed and disinfected immediately after making, to control transfer of infectious diseases from saliva and blood of the patient to dentists and technicians. Since sterilization of impressions is not possible because of high temperature and time needed, disinfection is the method of choice. But disinfection process may sometimes affect the properties of impression material. This study has undertaken to evaluate the efficacy and effect of chemical and U.V light disinfection on poly vinyl siloxane impressions.
