title: Disinfection of alginate impression material using disinfectants as mixing and soak solutions.
abstract: Disinfectant solutions were used as water substitutes in the preparation of specimens of alginate impression material. Chlorhexidine gluconate and sodium peroxysulphate solutions were tested. The alginate specimens were infected by sucking, subsequently disinfected in the solution used in the alginate preparation, and then tested for infectivity by 24-h incubation in thioglycollate broth. Bacterial growth was measured by changes in turbidity using a turbidimeter. The results indicate that chlorhexidine gluconate is an effective alginate disinfectant, when it is used as the liquid for alginate preparation and post-setting disinfection solution.
