“…During the early stage of plaque formation, the rate of adherence increases along with anaerobic bacteria, mainly Streptococcus. Furthermore, Candida and Staphylococcus increase proportionately in denture plaques (22). Therefore, it is hypothesized that oral hygiene decreases the overall number of bacteria and in particular Candida, blue pus bacillus and Staphylococcus, which have a relatively strong pathogenicity and may be the cause of opportunistic infectious diseases.…”

Abstract. With the growing number of elderly individuals, Candida is occasionally recognised as a fungal cause of aspiration pneumonia. In addition, there are numerous investigational reports on oral candidiasis. However, there are currently no reports on Candida contamination of denture base materials. This study was conducted to investigate Candida species in the oral cavity, denture parts and oral lesions of older/elderly subjects with oral candidiasis. The Candida strains were isolated and the species identified. Candida was also cultured in a medium with sample of denture resin and observed under an electron microscope. The results demonstrated the presence of several Candida species in the lesions of the oral mucosa and the surface and inner portions of the dentures. The following species of Candida were detected: Candida albicans, Candida glabrata, Candida tropicalis and Candida parapsilosis. Using electron microscopy, the invasion of Candida was observed in the incomplete polymerized resin base material and/or through microcracks (fissures) that have a tendency to form in used dentures. It was concluded that Candida may be present on the surface as well as the deeper portions of dentures. In addition, it appeared necessary to consider denture and oral cavity cleaning and the risks of remaking old dentures.

“…Recently, many investigations have focus more on biofilm formation than in planktonic cells to explain the bacterial behavior in the in vivo oral environment (19). Regarding candidiasis, few studies have investigated the bacteria-yeast relationship using clinical parameters that can modulate the biofilm formation on different surfaces (5,10,12). It is important to consider bacterial-Candida interactions in the study of fungal virulence.…”

“…In complex biofilms such as those found in the oral cavity, the ability of yeast to agglutinate with bacteria can be mediated by species interaction within the biofilm as well as by external factors like saliva, oral hygiene and exposure to antimicrobial agents (8,9). Despite the in vitro evidences of the Candida-bacteria interaction, few studies have investigated the S. mutans in patients with candidiasis or yeast related diseases (10,12). The aim of this study was to assess the number of Streptococcus mutans in saliva of patients with diagnosis of denture stomatitis before and after antifungal therapy.…”

Purpose: To assess the number of Streptococcus mutans in saliva of patients with denture stomatitis before and after antifungal therapy.Methods: After examining 93 patients, 47 were selected for fungal test. Then, from this sample, thirty patients were selected: 15 with positive and 15 with negative diagnosis for candidiasis that were evaluated for S. mutans counting, salivary flow and buffer capacity evaluation. Oral hygiene and prosthesis hygiene, period using prosthesis, lesion type and salivary data were related with clinical laboratorial characteristics of the patients with Candida.Results: The most frequent lesions were type I (43.5%) and II (53.5%). The amount of S. mutans was six times higher in patients with candidiasis and it was associated with low salivary flow and poor oral hygiene. After therapy, a reduction of S. mutans was verified particularly in patients with normal salivary flow. The values ranged from 0.01 to 3.88 x 10 4 cfu/mL.Conclusion: The data suggest that Streptococcus spp collaborates with Candida spp in the etiology and pathogenesis of denture stomatitis. The use of oral antimicrobial agents may provide a beneficial effect for denture stomatitis patients that are under antifungal therapy and that have poor oral hygiene and unfavorable salivary parameters.Key words: Dental prosthesis; antifungal agents; Candida; Streptococcus mutans ResumoObjetivo: Verificar o número de Streptococcus mutans em saliva de pacientes com estomatite protética antes e após a terapia antifúngica.Metodologia: Após exame clínico de 93 pacientes, 47 foram selecionados para exame micológico e desta amostra foram selecionados trinta pacientes: 15 com diagnóstico positivo e 15 com diagnóstico negativo de candidose foram avaliados para contagem de S. mutans, determinação de fluxo salivar e capacidade tampão. Higiene bucal e da prótese, tempo de confecção, tipo de lesão e dados salivares foram relacionados com características clínicas e laboratoriais de Candida.Resultados: As lesões frequentes foram dos tipos I (43,5%) e II (53,5%). A quantidade de S. mutans foi seis vezes maior em pacientes com candidose e foi associada com baixo fluxo salivar e higiene oral deficiente. Após a terapia, a redução de S. mutans foi verificada particularmente em pacientes com fluxo salivar normal. Os valores variaram de 0,01 a 3,88 UFC/ml x 10 4 .Conclusão: Os dados sugerem que os Streptococcus colaboram com Candida spp na etiopatogenia da estomatite protética. O uso de agentes antimicrobianos orais pode propiciar efeito benéfico para pacientes com estomatite protética submetidos à terapia antifúngica e que apresentam higiene oral deficiente e parâmetros salivares desfavoráveis.

The purpose of this study was to investigate oral flora in independent persons aged over 80 years with more than 20 remaining teeth. The subjects were 22 participants of the 8020 campaign (6 males and 16 females) with a mean age of ‫6.1ע3.18‬ years and an average of 24.7 teeth (Independent 8020 group). This group was compared with a group of 38 elderly people residing in nursing homes (10 males and 28 females) who had a mean age of ‫5.8ע3.18‬ years and an average of 4.2 teeth (Nursing group with fewer teeth). Saliva samples were collected from the vestibular areas of the maxilla and mandible using cotton swabs. Cell numbers of microorganisms were expressed as colony forming units/ml (CFUs/ml) and compared between the two groups. The average number of Staphylococcus species was 65.2‫4.47ע‬CFUs/ml in the Independent 8020 group and 400.3‫1.253ע‬CFUs/ml in the group with fewer teeth (pϽ0.01); that of Candida albicans was ‫7.73ע0.81‬ CFUs/ml in the Independent 8020 group and 152.9‫9.112ע‬CFUs/ml in the Nursing group with fewer teeth (pϽ0.05). Both species showed statistically significant differences between the two groups. This suggests that the Independent 8020 achiever group had better oral hygiene and that the presence of many teeth may be associated with an increased awareness of dental health.
