Abstract

As part of a study about the disinfection of impressions in dental treatment of elderly patients at home, we investigated the effect of immersion disinfection of alginate impressions on the dimensional accuracy and deformation of edentulous working casts in relation to the type of tray for alginate impressions. Two types of alginate impression materials : AROMA FINE DFIII (AFIII) and Jeltrate Plus (JLP), characterized by smaller or greater dimensional changes in water, were used. Four types of experimental metal trays (perforated trays opened or closed mesio-distally, unperforated trays opened or closed mesio-distally) were prepared as impression trays. Impressions were immersed in 1% sodium hypochlorite solution for 10 min or 2% glutaraldehyde solution for 30 min. Whichever tray to use for AFIII impression, the dimensional accuracy and deformation of edentulous working casts was only slightly affected by immersion in 1% sodium hypochlorite solution for 10 min.
