“…In the study reported here, an interesting finding was that 7% of subjects with mucosal lesions exhibited no growth of salivary yeasts. This finding is in accordance with findings by Bergendal andIsaksson (1983), Theilade et al (1983), Budtz-J6rgensen et al (1983) andKoopmans et al (1988). Numerous studies have shown that most denture plaque consists of Gram-positive bacteria of a benign type like the plaque ofnatural teeth, and less than 0.25%4 of denture plaque consists of yeasts (Koopmans et al, 1988).…”

“…Numerous studies have shown that most denture plaque consists of Gram-positive bacteria of a benign type like the plaque ofnatural teeth, and less than 0.25%4 of denture plaque consists of yeasts (Koopmans et al, 1988). This suggests that other factors, such as immunological reactions, could be responsible for denture stomatitis (Bergendal et al, 1979;Morimoto et al, 1987;Koopmans et al, 1988;Budtz-Jorgensen,1990).…”

Yeasts are commensals in the oral cavity and may not cause disease unless there are predisposing host factors, such as other disease, or when medication is being taken. The elderly are at increased risk of yeast infection. In this paper, prevalence of salivary yeasts in a group of 368 inhabitants of Helsinki aged 76, 81, and 86 years is reported. Salivary yeasts were counted by the Oricult-N dip-slide method, salivary secretion rate and buffering capacity were measured, type of dentition was noted, and signs of yeast infection and the occurrence of subjective symptoms were determined. There was no growth of yeasts in 25% of the subjects. From one to 20 colonies/slide were observed in 21%, 21-50 colonies in 21%, and over 50 colonies (a high count) in 33%. Subjects with low salivary flow rates and low buffering capacities had significantly higher yeast counts than did subjects with normal salivary flow rates and buffering capacities. High yeast counts were found in 19% of subjects with natural teeth. The corresponding percentages in those wearing partial or complete dentures were 32 and 41, respectively. High salivary yeast counts were associated with oral mucosal lesions but not with subjective complaints of oral symptoms.

“…Of additional interest was the apparent absence of Candida in the oral cavity of 13 (31%) DS patients. This finding supports the view that other microorganisms apart from Candida could contribute to DS and indeed previous studies have implicated a range of Gram-negative [31] and Gram-positive bacteria [32] with the condition.…”

Denture stomatitis (DS) is an inflammatory oral condition affecting most frequently the palatal mucosa covered by the fitting surface of a denture. The aim of this study was to determine the local cytokine profile generated in DS, as well as the level and identity of Candida involved. Palatal inflammation was determined by clinical indices in 93 upper denture-wearing subjects (42 with DS). The level of selected cytokines in palatal fluid was measured by cytometric bead array. Grouping of the cytokines associated with Th1, Th2, Th17 and regulatory T cell (Treg) responses, showed significant increases particularly for Th1 and Th17 responses. Using imprint culture, Candida was isolated from 48 patients (29 with DS). DS patients had significantly higher numbers of Candida isolated from the fitting surface of the denture (P=0.0113). However, there was significantly (P=0.03) higher numbers of Candida on the palate of non-DS patients. In summary, it would appear that an appropriate immune response is elicited in DS patients and whilst this appears to reduce Candida levels on inflamed mucosa, it is probable that Candida on the fitting surface of the denture remain protected from local immune responses which results in a continued reservoir of infection.

“…Placement of a prosthesis in the oral cavity results in profound alterations of the oral environment as the prosthesis becomes colonized with oral microorganisms and cuts off the underlying mucosa from the mechanical cleansing effect of the tongue and the free flow of saliva which may lead to a substantial shift in bacterial composition and can even lead to oral and systemic infections [4,5].…”

Objectives of this study were to see the types of aerobic microorganisms present in the saliva of Complete Denture wearing patients and to see any change in isolation frequency and types of microorganisms at 1-week of dentures in use. Materials and Methods: Ethical clearance from the institutional ethical committee and written consent from the patients were taken. All the patients were assessed by taking a detailed history and clinical examination which were recorded in the pre-designed proforma. Standard procedures accepted in the Department of Prosthodontics and in the Department of Microbiology were performed. Each patient were examined twice, once at 24hrs of denture insertion and then at 1-week of dentures in use. A micropippet was used to collect the resting saliva from the floor of the mouth and was diluted in 1ml of normal saline in a sterile vial and was immediately taken to the microbiology lab for culture within half an hour of sample collection. Result: Microorganisms identified at 24hrs of Complete Denture insertion were Streptococcus spp. (n=35), Staphylococcus spp. (n=15), Klebsiella pneumonia (n=5), Acinetobacter anitratus (n=5), Enterobacter cloacae (n=4), Citrobacter freundii (n=4), Pseudomonas aeruginosa (n=1) and Proteus vulgaris (n=1). Two new microorganisms were isolated at 1-week, Escherichia coli (n=1) and Candida albicans (n=2). Frequency of isolation of the gram negative bacteria increased at 1-week except for Proteus vulgaris. Conclusion: Use of Complete Denture favours colonization of some microorganisms which appear in saliva of patients.
