“…After the interview, the dentist performed an oral examination to assess oral status, the presence of dental plaque, and gum inflammation according to the Standard of Dental Examination in School Health and Safety Act (Japanese School Dental Association 2007). Denture plaque was assessed using a modification of the Ambjørnsen Denture Plaque Index (Ambjørnsen et al 1982). The presence of plaque on dentures was scored from 0 to 3 using the criteria proposed by Ambjørnsen, in which 0 is equivalent to no visible plaque, 1 is equivalent to plaque visible only by scraping on the denture base with a blunt instrument, 2 is equivalent to a moderate accumulation of dental plaque, and 3 is equivalent to an abundance of plaque.…”

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.

Nos idosos edêntulos, usuários de prótese total superior, foi empregado o índice de limpeza da prótese proposto por Ambjorsen et al 19 . A presença ou ausência de placa bacteriana foi registrada em cinco áreas da superfície interna da prótese total superior após uma rápida lavagem com água.…”

This study compared the application and reliability of 4 methods for biofilm quantification (computerized, paper-weighing, point-counting, and planimetric) in complete dentures, verifying the correlation between them. The internal surfaces of 62 complete dentures were stained (5% erythrosine) and photographed. The slides were projected on paper, and the areas (total and biofilm-covered) were outlined with a pencil. These areas were measured with an equidistant point grid (point-counting method), a digital planimeter (planimetric method), and for the paper weighing method they were cut and weighed with a precision scale. For the computerized method, ImageTool software was used. In order to perform a validation test of the methods, all of them were applied to slide projections of geometric figures with known dimensions. The correlation tests showed high correlation values (r = 0.82 to 0.99) among the methods. The validation test (ANOVA) showed no statistically significant differences among the values obtained from the measurement of figures using all four quantitative methods and the real dimensions of these geometric figures. Quantitative methods were efficient and reliable for measuring quantity of biofilm in complete dentures, and may be useful in experimental studies on the efficacy of hygiene products. The computerized method was fast and easy to perform. DESCRIPTORS: Denture, complete; Biofilms. RESUMO:Este estudo comparou a aplicação e a confiabilidade de quatro métodos de quantificação de biofilme (computadorizado, pesagem de papel, contagem de pontos e planimétrico) em próteses totais, verificando a correlação entre eles. As superfícies internas de 62 próteses totais foram coradas (eritrosina a 5%) e fotografadas. Os diapositivos foram projetados em papel, e as áreas (total e com biofilme corado) foram contornadas com grafite. Estas áreas foram medidas com uma grade de pontos eqüidistantes (método de contagem de pontos), um planí-metro digital (método planimétrico) e, para o método de pesagem de papel, foram recortadas e pesadas em balança de precisão. No método computadorizado, foram medidas com um software (ImageTool). Com o objetivo de realizar um teste de validação dos quatro métodos, estes foram aplicados também em diapositivos de figuras geométricas de dimensões conhecidas. Os testes de correlação mostraram altos valores de correlação (r = 0,82 a 0,99) entre os métodos. O teste de validação (ANOVA) não mostrou diferença estatisticamente significante entre as medidas reais dos desenhos geométricos e aquelas obtidas pelos quatro métodos quantitativos. Os métodos quantitativos mostraram-se eficazes e confiáveis na mensuração dos níveis de biofilme em próteses totais, podendo ser úteis em estudos experimentais da eficiência de produtos de higiene. O método computadorizado mostrou-se rápido e de fácil aplicação.
