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.

摘要

在藻酸盐印模材料标本制备中，使用消毒溶液替代水。对葡萄糖酸氯己定溶液和过氧硫酸钠溶液进行了测试。藻酸盐标本通过抽吸进行感染，随后在用于藻酸盐制备的溶液中进行消毒，然后在硫乙醇酸盐肉汤中孵育24小时以检测其传染性。使用比浊计通过浊度变化测量细菌生长。结果表明，当葡萄糖酸氯己定用作藻酸盐制备液和凝固后消毒溶液时，它是一种有效的藻酸盐消毒剂。
