The effects of hydrophobicities of substrate surfaces on microbial adherence were examined by using Candida albicans and Candida tropicalis and 21 denture base resin materials. With increasing surface free energy of resin plates, increasing adherence of C. albicans and decreasing adherence of C. tropicalis were observed. The surface free energy of C. albicans is higher than that of all resin material surfaces, and C. tropicalis has surface free energy lower than that of all materials used. In calculation of the changes of free energy accompanying the adherence, the higher adherence tendency was accompanied by a lower value for the free energy change in both species. From a different standpoint, the closer the surface free energy of the substrate surface and the microorganism, the higher was the probability of adherence.
通过使用白色念珠菌和热带念珠菌以及21种义齿基托树脂材料,研究了底物表面疏水性对微生物黏附的影响。随着树脂板表面自由能的增加,观察到白色念珠菌的黏附增加,而热带念珠菌的黏附减少。白色念珠菌的表面自由能高于所有树脂材料表面,而热带念珠菌的表面自由能低于所有所用材料。在计算黏附时自由能的变化时,两种菌中较高的黏附倾向都伴随着较低的自由能变化值。从不同的角度来看,底物表面和微生物的表面自由能越接近,黏附的可能性就越高。
