[Effect of disinfection on linear and dimensional stability of impression materials]

Given the potential for transfer of pathogenic microorganisms from dental impressions, a method for surface disinfection of impressions is needed to prevent spread of infection by way of impressions and casts made from them. The effects of disinfectant solutions on the impression materials linear and dimensional stability to prevent viral infections are investigated in this article. For this purpose, irreversible hydrokolloid and silicon rubber base impression materials and five disinfectant solutions were used. No apparent linear and dimensional change could be detected after 30 minute immersion in any of the disinfectants tested.
