“…Red wine (Vinho Tinto Seco Campo Largo, Vinícula Campo Largo, Campo Largo, Paraná, Brazil) was obtained from 750 mL bottles, and cola soft drink (The Coca-Cola Company, Curitiba, Paraná, Brazil) was obtained from 600 mL containers. [18] Distilled water was the control group solution. Specimens were randomly divided according to acrylic teeth/denture base resins combinations ( n = 8) and individually immersed in dark vials with 200 mL of tested solutions.…”

“…[1516] It has also been suggested that alcohol drinks such as wine promote softening and degradation of the material's polymeric surface. [1718] Moreover, low pH of acidic beverages like cola drinks can also damage the integrity of these materials. [1920] Therefore, in addition to staining, certain foods have an influence in other acrylic resin characteristics and might as well interfere on denture base/tooth bonding interface.…”

Background:Detachment of denture acrylic resin artificial teeth from denture base resin is one of the most common problems presented by denture wearers. Purpose: This study investigated the shear bond strength (SBS) and fracture type of bonding interface of two commercial acrylic teeth (Vipi Dent Plus e Biolux) to two denture base resins (Vipi Cril e Lucitone 550) after immersion in potentially chromogenic beverages (coffee, cola soft drink, and red wine) or control solution (distilled water).Materials and Methods:Maxillary central incisor acrylic teeth were placed at 45° to denture base resin and submitted to short polymerization cycle according to manufacturers. Specimens were divided according to the combination tooth/resin/solution (n = 8) and submitted to bond strength tests in a universal testing machine MTS-810 (0.5 mm/min). Subsequently, fracture area was analyzed by stereomicroscope at a magnification of ×10 and categorized into adhesive, cohesive, or mixed failure.Results:The bond strength of teeth/denture base resins interface was not significantly affected by tested solutions (P > 0.087), except for Biolux teeth immersed in coffee (P < 0.01). In all conditions, the Vipi Dent Plus teeth showed higher bond strength to Lucitone and Vipi Cril resins when compared to Biolux teeth (P < 0.003). All specimens’ failure modes were cohesive.Conclusions:The SBS of acrylic teeth to denture base resins was not generally influenced by immersion in the tested staining beverages.

“…These dentures are fabricated withacrylic resin, a low cost polymer material based on poly(methyl methacrylate) (PMMA), which is relatively easy to manipulate 3 . The acrylic resin may be classified according to its mode of activation , as chemically-polymerizated (cold-polymerized resins), heat-polymerizated (polymerized using water bath or microwave oven) and light-polymerizated types 4 .…”

Removable partial or complete dentures exposed to beverages and mouthwashes: evaluation of microhardness and roughness Descritores: Prótese dentária; base de prótese; resina acrílica; enxaguantes bucais. AbstractPurpose: To evaluate microhardness and roughness of denture base polymethylmethacrylate resinn exposed to acid beverages and mouthwashes. Material and method: Rectangular samples (n=80) were prepared from poly (methyl methacrylate) (PMMA). They were divided into 8 groups and had the initial microhardness and Knoop roughness measured. Samples of each group were immersed for 10 min into a test solution (coffee, lemon juice, chlorhexidine gluconate, red wine, cola-based soft drink, vinegar or antiseptic with and without alcohol) and after stored in artificial saliva for 23 h and 50 min, completing a period of 24 h. This procedure was performed for 14 consecutive days and after this period the microhardness and surface roughness measurements were made again. Data were statistically analyzed using ANOVA non parametric, Kruskal-Walis and the Dunn´s test for microhardness and the t-Student and ANOVA for roughness. Result: For microhardness there were found statistically significant differences among the chlorhexidine gluconate solution, antiseptic without alcohol and cola-based soft drink. For roughness was observed that the mean values between the initial period and after immersion in the test products differed statistically in all groups, without difference among groups. Conclusion: The microhardness of poly(methyl methacrylate) was affected by continue exposition to chlorhexidine gluconate, antiseptic without alcohol and cola-based soft drink. The roughness of poly(methyl methacrylate) is negatively influenced by the exposure to all tested products. It may be concluded that both, microhardness and roughness, were affected by the treatments.

“…The material should be translucent for the best esthetic effect. Color and translucency should be maintained during processing and acrylic resins should not become stained or change color in clinical use 6 .…”

Objective The aim of this study is to analyze if both color and nylon fibers have an influence on microwave-cured acrylic resin properties. MethodsRectangular and disk-shaped specimens were prepared using acrylic resins; medium pink with and without nylon fibers and colorless without nylon fibers. To obtain the rectangular specimens, a stainless steel die was used with the following dimensions: 64 X 10 x 3 mm (± 0.5mm RESUMO ObjetivoAnalisar se corantes e fibras de nylon influenciam nas propriedades de uma resina acrílica ativada por energia de micro-ondas. MétodosEspécimes retangulares e em forma de disco foram confeccionados em resina acrílica rosa médio com e sem fibras de nylon e incolor sem fibras. Para obter os espécimes retangulares, foi utilizada uma matriz de aço inoxidável com as seguintes dimensões: 64 X 10 X 3 (± 0,5mm) e para obter os espécimes em forma de disco, foi utilizada uma matriz com 50mm (± 0,5mm) de diâmetro e 0,5mm (±0,05mm) de espessura. Os mesmos foram randomizados para formar os grupos controle (acrílico incolor sem fibras) e experimentais (rosa médio com e sem fibras), sendo cada grupo composto por dez (10) espécimes retangulares e cinco (5) em forma de disco. Foram os mesmos então submetidos a seis (6) ensaios (resistência ao impacto izod, n=10; dureza knoop, n=10; temperatura de transição vítrea, n=3; sorção e solubilidade, n=5; grau de conversão, n=1; resistência à flexão e módulo de flexão, n=10). Todas as variáveis foram submetidas à análise de variância seguida pelo teste de comparações múltiplas de Tukey, com nível de significância de 5%.Resultados O grau de conversão foi de 88% para os 3 grupos de resinas e os resultados não mostraram diferença estatisticamente significativa entre os mesmos para cada variável (p>0,05). ConclusãoOs resultados mostraram que o corante e a presença de fibras de nylon em resina acrílica não afetaram as propriedades analisadas nesse estudo.

Color Stability of Resins and Nylon as Denture Base Material in Beverages

Abstract: Chromatic changes were exhibited by specimens immersed in red wine, followed by coffee. For Transflex, cola also promoted color changes. The values of color changes converted to National Bureau of Standard units showed them to be perceivable to the human eye.
