“…Thus, the mechanical cleaning combined with effective and inexpensive chemical aids, such as sodium hypochlorite and coconut soap, seems to be more appropriate (15). Although the habit of wearing dentures during sleep is important on DML development, especially denture stomatitis (16), this study did not find a statistical association between these variables. According to Emami et al (17), nocturnal wearing of the dentures can reduce the protective effect of saliva, by cleaning the tongue, and good oxygenation of the mucosa, which are key factors in the resistance of mucosal tissue to mechanical and microbiological aggression.…”

Objectives: The purpose of this study was to evaluate the prevalence of denture-related oral mucosal lesions (DML) in São Francisco sertão microregion, in Sergipe State, Northeastern Brazil. Study Design: Data related to gender, age, type of denture, length of denture use, hygiene care, nocturnal denture wear, symptoms, and presence of DML were obtained. Statistical analysis included the Pearson's chi-square and multivariate logistic regression. Results: The global prevalence of DML was 50%, with a significant association between the DML and female gender, age ≥ 40 years, and length of use ≥ 5 years. By using the interaction model of logistic regression it was observed that females over 40 years have 4.5 greater odds of developing DML compared to males of the same age group. The DML more common was the type 2 denture stomatitis, followed by type 1 denture stomatitis and inflammatory fibrous hyperplasia. Conclusions: This study shows that the DML are more common in female over 40 years of age, suggesting that hormonal chances and age-related factors may favor the development of lesions. In addition, there is a significant association between length of denture use and prevalence of DML.

“…First, even in a healthy older adult, aspiration of unnoticed oropharyngeal and periodontal secretions occurs during sleep, and a high incidence of silent aspiration is strongly related to pneumonia among the elderly (Kikuchi et al 1994), particularly those with dementia or cerebrovascular disease. Denture wearing during sleep was reported to be associated with poor denture hygiene, oral candidiasis (Compagnoni et al 2007), and denture stomatitis (Baran and Nalçaci 2009;Fenlon et al 1998;Shulman et al 2005;Vigild 1987), all of which may function as reservoirs of potentially infectious pathogens (Sumi et al 2010). Our findings that denture wearers during sleep had significantly higher rates of denture and tongue plaque and oral candidiasis provide additional evidence for this suggestion.…”

Denture Wearing during Sleep Doubles the Risk of Pneumonia in the Very Elderly

et al. 2014

Poor oral health and hygiene are increasingly recognized as major risk factors for pneumonia among the elderly. To identify modifiable oral health–related risk factors, we prospectively investigated associations between a constellation of oral health behaviors and incident pneumonia in the community-living very elderly (i.e., 85 years of age or older). At baseline, 524 randomly selected seniors (228 men and 296 women; mean age, 87.8 years) were examined for oral health status and oral hygiene behaviors as well as medical assessment, including blood chemistry analysis, and followed up annually until first hospitalization for or death from pneumonia. During a 3-year follow-up period, 48 events associated with pneumonia (20 deaths and 28 acute hospitalizations) were identified. Among 453 denture wearers, 186 (40.8%) who wore their dentures during sleep were at higher risk for pneumonia than those who removed their dentures at night (log rank P = 0.021). In a multivariate Cox model, both perceived swallowing difficulties and overnight denture wearing were independently associated with an approximately 2.3-fold higher risk of the incidence of pneumonia (for perceived swallowing difficulties, hazard ratio [HR], 2.31; and 95% confidence interval [CI], 1.11–4.82; and for denture wearing during sleep, HR, 2.38; and 95% CI, 1.25–4.56), which was comparable with the HR attributable to cognitive impairment (HR, 2.15; 95% CI, 1.06–4.34), history of stroke (HR, 2.46; 95% CI, 1.13–5.35), and respiratory disease (HR, 2.25; 95% CI, 1.20–4.23). In addition, those who wore dentures during sleep were more likely to have tongue and denture plaque, gum inflammation, positive culture for Candida albicans, and higher levels of circulating interleukin-6 as compared with their counterparts. This study provided empirical evidence that denture wearing during sleep is associated not only with oral inflammatory and microbial burden but also with incident pneumonia, suggesting potential implications of oral hygiene programs for pneumonia prevention in the community.

“…Another habit for the maintenance of complete dentures, overnight removal, was previously tested by another trial and associated with lower counts of Candida spp. if compared with continuous wearing (34). Previous studies which employed DNA checkerboard hybridization found differences among specific areas of the edentulous mouth (29), as well as changes after the insertion of dental implants (35).…”

To investigate the effect of the home use of a disclosing agent on the microbial composition of denture biofilm, by means of a cross-over randomized clinical trial. Two interventions were tested during 7 days each: (I) oral and denture hygiene instructions and (II) instructions associated with the home use of a disclosing agent (1% neutral red). Eleven participants with visible biofilm deposits over their maxillary complete dentures were randomly assigned to one of the two sequences of interventions: (i) I followed by II, and (ii) II followed by I. A washout period of 7 days was established. After each intervention, samples of denture biofilm were evaluated by DNA checkerboard hybridization for the detection of Candida spp. and 17 bacterial species. Counts were low for all the tested species, and no significant difference was found between the tested interventions (Wilcoxon test, P > 0.05). The home use of a disclosing agent does not remarkably change the composition of denture biofilm.
