The aim of this study was to evaluate the antibacterial and antifungal properties of polyether impression materials using the agar diffusion test. Three different types of polyether impression materials (P2, Penta Soft and Penta) were tested to determine their ability to inhibit the growth of Enterococcus faecalis, Staphylococcus aureus, Pseudomonas aeruginosa, and Candida albicans. The areas of inhibition zones were measured visually with a 0.1-mm incremental Boley gauge. In all groups, none of the samples of the P2 polyether impression material exhibited antibacterial or antifungal activity against any of the microorganisms. All Penta Soft and Penta samples exhibited antibacterial activity against E. faecalis and S. aureus, and only Penta samples exhibited antifungal effect against C. albicans, which decreased progressively as the setting time of the material increased.
本研究的目的是使用琼脂扩散试验评估聚醚印模材料的抗菌和抗真菌特性。测试了三种不同类型的聚醚印模材料（P2、Penta Soft和Penta），以确定它们抑制粪肠球菌、金黄色葡萄球菌、铜绿假单胞菌和白色念珠菌生长的能力。用0.1毫米增量的博利测径器目视测量抑菌圈面积。在所有组中，P2聚醚印模材料的样本均未对任何微生物表现出抗菌或抗真菌活性。所有Penta Soft和Penta样本均对粪肠球菌和金黄色葡萄球菌表现出抗菌活性，只有Penta样本对白色念珠菌表现出抗真菌作用，且随着材料凝固时间的增加，这种作用逐渐减弱。
