Objective: To evaluate the clinical efficacy of Schinus terebinthifolius Raddi (aroeira) tincture in the treatment of denture stomatitis. Method: Eighteen removable denture wearers with clinical diagnosis of type II denture stomatts and presence of candidosis associated to the denture use, as confirmed by clinical and mycological examinations, were selected for the study. The patients were allocated to two groups: TG (test group) - treatment with Schinus terebinthifolius Raddi (aroeira) tincture; CG (control group), treatment with nystatin. All patients were instructed to clean the dentures with toothbrush and dentifrice, and then apply the product on the palatal mucosa and on denture surface 3 times a day, during 15 consecutive days, removing the denture at bedtime and keeping it in a receptacle with water. At the 15th day of use, the clinical and mycological examinations were redone to evaluate treatment efficacy. Data were analyzed statistically by Wilcoxon and Mann-Whitney tests at 5% significance level. Results: The inflammatory process and Candida spp. infect on were eliminated in 66.7% and 77.8% of the cases, respectively, in TG. In CG, elimination of the inflammatory process and fungal infect on occurred in 77.8% and 88.9% of the cases, respectively. These results were statistically significant (p=0.01). There was no statistically significant difference between the treatments (p>0.05). In all cases, fungal infect on was detected only on the denture, and C. albicans was the most prevalent microorganism, being present in 94.4% of the cases. Conclusion: The treatment with Schinus terebinthifolius Raddi (aroeira) tincture was effective in the treatment of denture stomatitis, promoting remission of the inflammatory process and Candida spp infection.

Objectives: To compare the oral prevalence and antimicrobial susceptibility of Candida spp., staphylococci, enterobacteriaceae, and pseudomonas spp.from ankylosing spondylitis (AS) patients receiving conventional and anti-TNF-α therapy. Methods: The study included 70 AS patients, diagnosed according to the modified New York criteria (1984). The volunteers were divided into 2 groups: a biological group (AS BioG) (n=35) (on anti-TNF-α therapy) and a conventional group (AS ConvG) (n=35). The control group (ContG) (n=70) was made up of healthy individuals matched for age, gender, and oral conditions. After clinical examination, oral rinse samples were collected and plated in specific culture media. The number of colony-forming units per milliliter (cfu/ml) was obtained, and isolates were identified using the API system. Antimicrobial susceptibility tests were performed according to the NCCLS guidelines. Prevalence and counts of microorganisms were statistically compared between the 3 groups, using the Mann-Whitney and Chi-square tests. Significance level was set at 5%. Results: In both the AS BioG and the AS ConvG, staphylococci counts were higher than that in the ContG (p<0.0001). Candida albicans and staphylococcus epidermidis were the most commonly found species in all the groups. Serratia marcescens and klebsiella oxytoca were more prevalent in the AS BioG and the AS ConvG, respectively. Two Candida isolates (2.8%) from the AS BioG and 5 (10.8%) from the AS ConvG were resistant to amphotericin B and 5-fluorocytosine. A low percentage of staphylococci isolates was resistant to amoxicillin, ciprofloxacin, and doxycycline. Conclusion: Higher counts of staphylococci were observed in both AS groups, regardless of the current therapy, age, sex, and oral conditions. Anti-TNF-α therapy could not be correlated with increased counts of microorganisms. © Copyright CLINICAL AND EXPERIMENTAL RHEUMATOLOGY 2012.

This study compared the effectiveness of Ricinus communis (RC) with Nystatin (NYS) and Miconazole (MIC) in the treatment of institutionalised elderly with denture stomatitis (DS). They (n = 30) were randomly distributed into three groups: MIC, NYS or RC. Clinical and mycological evaluations were performed prior to the use of the antifungal (baseline) and repeated after 15 and 30 days of treatment. The sample was clinically examined for oral mucosal conditions. Standard photographs were taken of the palate, and the oral candidiasis was classified (Newton's criteria). Mycological investigation was performed by swabbing the palatal mucosa, and Candida spp. were quantified by counting the number of colony-forming units (cfu mL-1). The clinical and mycological data were analysed, respectively by Wilcoxon and Student's t-test (α = 0·05). Significant improvement in the clinical appearance of DS in the MIC and RC groups was observed between the 1st and 3rd collections (MIC - P = 0·018; RC - P = 0·011) as well as between the 2nd and 3rd collections (MIC - P = 0·018; RC - P = 0·011). Neither groups showed a statistically significant reduction in cfu mL-1 at any time. Although none of the treatments decreased the cfu mL-1, it was concluded that Ricinus communis can improve the clinical condition of denture stomatitis in institutionalised elderly patients, showing similar results to Miconazole. © 2013 Blackwell Publishing Ltd.

The aim of this study was to isolate, quantify, identify, and compare opportunistic microorganisms (Candida and Staphylococcus genera and Enterobacteriaceae/Pseudomonadaceae families) from prosthesis-fitting surfaces, the hard palate, and mouth rinses of individuals wearing removable maxillary prosthesis with (50) and without (50) lesions of denture stomatitis (DS). The strains were collected and identified using phenotypic, biochemical and molecular tests. The counts of microorganisms were significantly higher in the group of individuals with DS (P < 0.05). C. albicans was the most frequently isolated yeast species in both groups, following by C. tropicalis and C. glabrata. Six isolates were identified as C. dubliniensis. S. aureus and S. epidermidis were the most frequent Staphylococcus species in both groups. Klebsiella pneumoniae was the predominant species in both groups. The association between Candida spp. and bacteria isolated in this study with DS suggests that these microorganisms may play important roles in the establishment and persistence of this disease. © 2013 Elsevier Inc.
