The various factors in relation to existence of fungi in denture plaque accumulated on the mucosal surface of denture plate were studied. Fungi were isolated from denture plaque of 57 patients (23 males and 34 females) and dental plaque of 50 students. Fungi were identified by means of minitek system (B.B.L.) and Candida check (latron). Isolation frequency of fungi was shown by percentage of patients which fungi isolated. The results were as follows: 1. Isolation frequency of fungi from denture plaque was 86% and much higher than that of dental plaque (18%). 2. Candida albicans was isolated from both plaque, but Candida tropicalis and Torulopsis glabrata were only detected in denture plaque. 3. The species and frequency of fungi isolated from denture plaque were increased with increase of wearing period or in case of denture with complicated design. 4. Not only coccoid and filamentous cells but fungusform cells were observed in denture plaque by scanning electron microscopy.
