Agar impression materials, dimensional stability and surface detail sharpness following treatment with disinfectant solutions.
The influence of seven dissimilar disinfectants on the dimensional stability and the surface detail sharpness of two agar impression materials was studied. Two methods for treatment with disinfectant solutions were tested--immersion for 1 hour and spraying. In contrast to immersion the spraying method had no obvious influence on the agar material. It is concluded that if the disinfection method necessitates immersion of the impression in a solution for 1 hour or more the use of agar impression materials should be avoided.
