English abstract The efficacy of 2 oral hygiene products, an experimental toothpaste specific for complete denture cleansing and a regular standard toothpaste, was compared in terms of denture biofilm removal and cure of palatal lesions in patients with atrophic chronic candidiasis. The degree of correlation between presence of biofilm and mucosa erythema was also evaluated. Twenty-four complete denture wearers (45-80 years old) were divided into 2 groups: experimental paste and standard toothpaste (Sorriso-Kolynos, Brazil). Both groups received soft toothbrushes. The internal surfaces of upper dentures were stained using 1% sodium fluorescein and photographed at a 45º angle at 0, 15, 30 and 60 days. The slides were scanned and the areas of interest (denture total area and biofilm area) were measured (Image Tool software). The degree of erythema was evaluated on slides according to the Prosthesis Tissue Index. There was a significant reduction (1%) in the degree of biofilm (ANOVA/Tukey) between the two initial visits (0 and 15 days) and the two final visits (30 and 60 days), and in the average erythema scores (Kruskal-Wallis) between 0 and 60 days, in both groups. The Mann-Whitney test showed a significant difference (1%) between pastes in terms of biofilm degree, but no difference was found for the erythema score. Correlation values between biofilm and erythema degree were 0.3801 (experimental paste) and (0.3678 (standard toothpaste). We may therefore conclude that the experimental product was efficient for the removal of denture plaque biofilm
Portuguese abstract Foram comparadas duas pastas, específica para prótese total e convencional para dentes naturais, quanto à habilidade de remoção de biofilme e cura de lesões do palato em pacientes com Candidíase Atrófica Crônica. Avaliou-se também o grau de correlação entre biofilme e grau de eritema. Vinte e quatro pacientes (45-80 anos) foram distribuídos em: a) pasta específica (produto experimental); b) pasta convencional (pasta dental Sorriso). Para ambos os grupos foram fornecidas escovas dentais de cerdas macias. Assuperfícies internas (próteses superiores) foram evidenciadas (fluoresceína 1%) e fotografadas (45º) em 4 visitas (0, 15, 30 e 60 dias). Os slides foram escaneados e as áreas (total e biofilme) foram medidas (software Image Tool). Sobre slides avaliou-se o grau de eritema empregando-se o Índice Tecidual de Prótese. Houve redução significativa (1%) dos níveis de biofilme (análise de variância) entre as primeiras (0 e 15 dias) e últimas visitas (45 e 60 dias) e dos escores de eritema (Kruskal-Wallis) da primeira para quarta vistita para ambas pastas. O teste de Mann-Whitney mostrou diferença estatística entre as pastas para os níveis de biofilme e igualdade estatística para os escores de eritema. Os valores de correlação entre níveis de biofilme e grau de eritema foram de 0,3801 (pasta específica) e 0,3678 (pasta convencional). A pasta específica mostrou-se efetiva, mostrando que é possível a manutenção da higiene de próteses totais com o uso regular de higienizador em forma de pasta
