“…In the present study, the color differences were considered "appreciable" and "much appreciable" for the 5% and 10% PTBAEMA groups, respectively. This could be explained by the chemical affinity of the polycationic polymer PTBAEMA with acrylic resin, since copolymerization between PTBAEMA and a denture base resin have been observed in a previous study 30 . Considering that the clinical relevance of color differences is subjective, future in vivo studies could be performed to assess the impact of the color stability of acrylic resins modified by PTBAEMA on the satisfaction of denture wearers.…”

ResumoIntrodução: A ocorrência de estomatite protética é relativamente comum uma vez que as superfícies das próteses bucais representam um ambiente propício para adesão de microrganismos orais e formação de biofilme. Objetivo: Avaliar as propriedades de superfície (molhabilidade/rugosidade) e estabilidade de cor de uma resina acrílica combinada com o polímero antimicrobiano poli (2-tert-butilaminoetil) metacrilato (PTBAEMA). Material e método: Trinta espécimes em formato de disco de uma resina acrílica (Lucitone 550) foram divididos em três grupos: 0% (controle), 5% e 10% PTBAEMA. Os valores de rugosidade (Ra) foram medidos utilizando um rugosímetro, e a molhabilidade foi determinada através de medições de ângulo de contato utilizando um goniômetro e água deionizada como líquido teste. Dados de cores foram medidos com um espectrofotômetro. Os testes de Kruskal-Wallis e Dunn foram utilizados para comparar os valores de rugosidade. Os dados de molhabilidade foram analisados utilizando-se ANOVA e teste de Tukey. Os dados de cor foram comparados com o teste t de Student e valores ΔE foram classificados de acordo com o National Bureau of Standards (NBS). Todas as análises estatísticas foram realizadas considerando α = 0,05. Resultado: Diferenças significativas (p<0,05) foram detectadas entre os grupos para rugosidade, molhabilidade, e estabilidade de cor. De acordo com o NBS, as alterações de cor obtidas nos grupos 5% e 10% PTBAEMA foram "marcante" e "extremamente marcante", respectivamente. Conclusão: Pode-se concluir que a incorporação de PTBAEMA em uma resina acrílica aumentou a rugosidade e molhabilidade das superfícies e produziu alterações de cor com relevância clínica.Descritores: Resinas acrílicas; produtos com ação antimicrobiana; molhabilidade; cor, propriedades físicas. AbstractIntroduction: The occurrence of stomatitis is common since the surface characteristics of the dentures may act as reservoirs for microorganisms and have the potential to support biofilm formation. Purpose: To assess the surface properties (wettability/roughness) and color stability of an acrylic resin combined with the antimicrobial polymer poly (2-tert-butylaminoethyl) methacrylate (PTBAEMA). Material and method: Thirty disc-shaped specimens of an acrylic resin (Lucitone 550) were divided into three groups: 0% (control); 5% and 10% PTBAEMA. Surface roughness values (Ra) were measured using a profilometer and wettability was determined through contact angle measurements using a goniometer and deionized water as a test liquid. Color data were measured with a spectrophotometer. Kruskal-Wallis and Dunn's test were used to compare roughness values. Wettability data were analyzed using ANOVA and Tukey's test. Color data were compared using the Student's t-test and ∆E values were classified according to the National Bureau of Standards (NBS). All statistical analyses were performed considering α=.05. Result: Significant differences (p<.05) were detected among the groups for roughness, wettability and color stability. According to the NBS,...

“…Large polymer chains can move freely at Tg 18) though such movement is dependent on the molecular structure, as well as degree of cross-linking and branching 5) . Thermal properties including the Tg values of materials used for dentures have primarily been investigated by dynamic mechanical analysis (DMA) 3,8,15,[18][19][20] and differential scanning calorimetry (DSC) 18,21,22) . Dynamic mechanical analysis is one of the most useful techniques available for evaluating the mechanical properties of materials with cyclic applications of stress and temperature.…”

This study assessed methods for evaluation of glass transition temperature (Tg) of autopolymerized hard direct denture reline resins using dynamic mechanical analysis and differential scanning calorimetry in addition to the dynamic mechanical properties. The Tg values of 3 different reline resins were determined using a dynamic viscoelastometer and differential scanning calorimeter, and rheological parameters were also determined. Although all materials exhibited higher storage modulus and loss modulus values, and a lower loss tangent at 37˚C with a higher frequency, the frequency dependence was not large. Tg values obtained by dynamic mechanical analysis were higher than those by differential scanning calorimetry and higher frequency led to higher Tg, while more stable Tg values were also obtained by that method. These results suggest that dynamic mechanical analysis is more advantageous for characterization of autopolymerized hard direct denture reline resins than differential scanning calorimetry.
