Microscopic evidence of Candida albicans present in prosthetic bases removed of buccal cavity

[摘要] Aim of present paper is to determine the Candida albicans adherence to ultrastructure of thermo-cure acrylic resins (PPMA) used in total dentures bases confection. We used 2 samples of PPMA: first from the used dentures bases; choosing 12 completely edentulous patients carriers of dentures and diagnosed with sub-prosthetic stomatitis (SPE) and from this group we choose one at random; the second sample from the PPMA newly developed by the traditional thermo-cure protocol. Observing and comparing both samples in SEM, it was possible to demonstrate the presence of hyphae, pseudo-hyphae, and chlamydospores in the firs sample even hyphae entering to structure defects inherent to elaboration process. In the second sample there was a marked topographic differentiation. Microscopic evidence showed the Candida adhesion in sample from used dentures.
