Abstract

Using microbiologically experimental methods and observations corresponding to praxis the efficiency of the addition of antiseptics to alginate is evaluated. The addition of chlorhexidine to the alginate leads to a considerable reduction of the amounts of germs, but an one hundred percent disinfection of the alginates is not always performed. An influence of the alginate materials and the water quality on the antimicrobial efficacy of chlorhexidine has been proved. The always occurring contamination of the impression tray rules out a complete stopping of infection between the patient and the laboratory staff.

自消毒藻酸盐压印材料的微生物学研究
采用微生物学实验方法和与实践相对应的观察,评价了在海藻酸盐中添加防腐剂的效率。在海藻酸盐中加入氯己定可以大大减少细菌的数量,但并不总是对海藻酸盐进行百分之百的消毒。研究了藻酸盐原料和水质对氯己定抑菌效果的影响。总是发生的印模盘污染排除了完全停止患者和实验室工作人员之间的感染。
