The aim of this study is to verify whether removable dentures of patients admitted to an intensive care unit (ICU) are niches of microorganisms that can cause pathologies (, , and enterobacteria).
Fifteen patients who were denture wearers (removable partial denture and complete denture) were included in this study. Patients must wear their dentures daily, and these dentures must have acrylic parts. Microbial biofilm was collected from the acrylic part of one denture of each patient. Then, the biofilm was seeded on different culture media: Sabouraud agar, blood agar, MacConkey agar, and mannitol salt agar. In this study, biochemical evaluations of microorganisms were performed.
The percentage of dentures with the microorganism identified by each culture medium was calculated.
In total, 100% of the dentures were positive for (blood agar) and (Sabouraud agar); 33.3% of the dentures were positive for (Mannitol salt agar); and 13.3% of the dentures were positive for (MacConkey agar).

本研究旨在验证重症监护病房(ICU)患者的可摘义齿是否为可导致病变的微生物(白色念珠菌、金黄色葡萄球菌和肠杆菌)的滋生地。
本研究纳入了15名佩戴义齿(可摘局部义齿和全口义齿)的患者。患者必须每天佩戴义齿,且这些义齿必须有丙烯酸部件。从每位患者一副义齿的丙烯酸部件上采集微生物生物膜。然后,将生物膜接种在不同的培养基上:沙氏琼脂、血琼脂、麦康凯琼脂和甘露醇盐琼脂。在本研究中,对微生物进行了生化评估。
计算每种培养基鉴定出的带有微生物的义齿的百分比。
总体而言,100%的义齿在血琼脂上检测出金黄色葡萄球菌呈阳性,在沙氏琼脂上检测出白色念珠菌呈阳性;33.3%的义齿在甘露醇盐琼脂上检测出金黄色葡萄球菌呈阳性;13.3%的义齿在麦康凯琼脂上检测出大肠埃希菌呈阳性。
入住ICU的患者的可摘义齿(可摘局部义齿和全口义齿)是可导致病变的微生物的滋生地。
