To investigate the quantity and frequency of colonization of yeast-like fungi in denture plaque and saliva, specimens were obtained from denture surface and saliva in 75 denture wearers and 30 non denture wearers. The frequency of fungal colonization in denture plaque was 77.3% There were a larger number of fungi on the mucosal surface of the denture (especially the upper denture) than on the polishing surface. The frequency of colonization in saliva of denture wearers was 58.7% The quantity of colonization in denture plaque correlated to that in saliva. On the other hand, the frequency of colonization in saliva was only 26.7% in subjects without dentures. So-called denture-induced stomatitis was seen in 44.0% of all denture wearers and the quantity of colonization in denture plaque on the upper mucosal surface correlated to the incidence of the disease. It was not determined in this study whether yeast-like fungi (mainly Candida albicans) caused denture-induced stomatitis. But it was confirmed that denture plaque may cause the multiplication of yeast-like fungi and greatly influence their quantity in saliva.
