Species of Streptococcus, Escherichia coli, Staphylococcus, Actinomyces, Pseudomonas, Klebsiella, and Candida are commonly seen in the oral cavity. Impression materials are commonly contaminated with microorganisms. The present study was conducted to assess the disinfection efficacy of Epimax and 0.525% sodium hypochlorite on alginate impression over a period of 10 minutes.
This study was conducted in the Department of Prosthodontics in the year 2015. An alginate impression material was prepared. For each bacteria species, 15 samples were used. Out of 15 samples, 3 were used by 0.525% sodium hypochlorite for disinfection for 5 minutes and 3 others for 10 minutes. Similarly, 3 samples were used by Epimax for 5 minutes and other 3 for 10 minutes. Three samples were used as controls. Each sample was polluted with Candida albicans, Pseudomonas aeruginosa, and Staphylococcus aureus strains.
There was no statistical difference in P. aeruginosa and C. albicans after 5 minutes, whereas S. aureus showed significant difference (p < 0.05). Epimax was found to be more effective in removing S. aureus as compared with other disinfectants. Both Epimax and 0.525% sodium hypochlorite did not show significant difference against P. aeruginosa and C. albicans, whereas significant difference was found between both agents against S. aureus (p < 0.05). It was seen that Epimax eliminated S. aureus after 5 minutes and P. aeruginosa after 10 minutes and 99.8% C. albicans after 10 minutes. About 0.525% sodium hypochlorite eliminated 99.1% of C. albicans after 10 minutes, whereas 98.5 and 99% of S. aureus and P. aeruginosa were eliminated after 10 minutes respectively.
Both Epimax and 0.525% sodium hypochlorite can disinfect the alginate impression material against C. albicans, P. aeruginosa, and S. aureus strains. However, Epimax was found to be more effective against S. aureus as compared with 0.525% sodium hypochlorite.

口腔中常见的链球菌、大肠杆菌、葡萄球菌、放线菌、假单胞菌、克雷伯菌和念珠菌等菌种。印模材料常被微生物污染。本研究旨在评估Epimax和0.525%次氯酸钠在10分钟内对藻酸盐印模的消毒效果。
本研究于2015年在口腔修复科进行。制备了一种藻酸盐印模材料。对于每种细菌菌种，使用15个样本。在15个样本中，3个样本用0.525%次氯酸钠消毒5分钟，另外3个样本消毒10分钟。同样，3个样本用Epimax消毒5分钟，另外3个样本消毒10分钟。3个样本用作对照。每个样本用白色念珠菌、铜绿假单胞菌和金黄色葡萄球菌菌株污染。
5分钟后，铜绿假单胞菌和白色念珠菌无统计学差异，而金黄色葡萄球菌有显著差异（p<0.05）。与其他消毒剂相比，Epimax在去除金黄色葡萄球菌方面更有效。Epimax和0.525%次氯酸钠对铜绿假单胞菌和白色念珠菌均无显著差异，而两种制剂对金黄色葡萄球菌有显著差异（p<0.05）。结果显示，Epimax在5分钟后可消除金黄色葡萄球菌，10分钟后可消除铜绿假单胞菌，10分钟后可消除99.8%的白色念珠菌。约0.525%次氯酸钠在10分钟后可消除99.1%的白色念珠菌，而10分钟后分别可消除98.5%和99%的金黄色葡萄球菌和铜绿假单胞菌。
Epimax和0.525%次氯酸钠均可对藻酸盐印模材料进行消毒，以对抗白色念珠菌属、铜绿假单胞菌和金黄色葡萄球菌菌株。然而，与0.525%次氯酸钠相比，Epimax对金黄色葡萄球菌更有效。
