“…But also smoking leads to discolorations on teeth and dental restorations. Intrinsic factors are chemical reactions within the restoration material triggered heredity, age and processing modes of placed restorations [21]. The processes which lead to discoloration of PEEK still remain to be elucidated.…”

“…Based on the literature reviewed, 90 specimens were prepared, so that each sample group had 10 samples [8][9][10][11][12]14,15]. Each specimen had its width at 8 mm and its height at 2 mm, as in the study carried out by Kumari et al in 2015.…”

“…The results did not show this protection from staining, just as in 2012, Szesz et al evaluated the possibility of this procedure to minimize or solve the stain caused by beverages, but concluded that there was no effectiveness in the action. In 2013, Falkensammer et al also polished their samples, with no success Other studies used the mark of one week in their evaluations, but with a temporal continuity, as 14 days [5,14], 28 days [17,18], 60 days [9,16] and up to 90 days [7].…”

ResumoObjetivo: Avaliar se bebidas alcóolicas podem provocar alteração de cor em resinas compostas, se a concentração alcóolica tem influência nesta variação além de analisar dentre as resinas compostas testadas, qual apresentaria maior estabilidade de cor quando submetidas ao experimento. Material e métodos: Foram confeccionados 90 espécimes de 3 diferentes resinas compostas (IPS Empress Direct, Grandio®So e Filtek Z350 XT) e imersos em água destilada (grupo controle), vinho tinto e vodca. As amostras mediam 2 mm de espessura e 8 mm de diâmetro, foram fotopolimerizados por 20 s cada lado, polidos com disco de lixa, ponta de carbeto de silício e disco de feltro com pasta profilática e imersos em água destilada a 37 ºC por 24 h antes da divisão em subgrupos. Para a avaliação da variação de cor foi utilizada a fórmula priorizada pelo sistema CIEL*a*b*. Os dados foram analisados por ANOVA e teste de Tukey a 95% de significância. Resultados: As menores variações ocorreram com a resina Grandio®So quando exposta ao vinho, e a Filtek Z350 XT quando exposta à vodca. Houve diferença estatisticamente significante entre os grupos na água (p < 0.01) e no vinho tinto (p < 0.01), mas não na vodca (p > 0,05). O meio de imersão que mais causou manchamento foi o vinho tinto. Conclusão: O vinho tinto foi a bebida que gerou o maior manchamento em todas as resinas testadas, a vodca não alterou a estabilidade de cor de maneira significativa, as concentrações alcóolicas testadas não influenciaram diretamente na alteração de cor e a resina composta Grandio®So apresentou maior estabilidade de cor frente ao vinho tinto. ABsTRACTObjective: To evaluate if alcoholic beverages can cause color change in composite resins, if the alcoholic concentration influences this variation besides analyzing within the composite resins tested, which would present greater color stability when subjected to the experiment. Material and Methods: 90 specimens of three different composite resins (IPS Empress Direct, Grandio®So and Filtek Z350 XT) were immersed in distilled water (control group), red wine and vodka. The samples were 2 mm thick and 8 mm in diameter, photopolymerized for 20 s on each side, polished with sandpaper, silicon carbide tip and felt disc with prophylactic paste and immersed in distilled water at 37 °C for 24 h prior to subgrouping. For the evaluation of the color variation, the formula prioritized by the CIEL *a *b* system was used. Data were analyzed by ANOVA and Tukey's test at 95% significance. Results: The lowest variations occurred with the Grandio®So resin when exposed to wine, and Filtek Z350 XT when exposed to vodka. There was a statistically significant difference between the groups in water (p < 0.01) and in red wine (p < 0.01), but not in vodka (p > 0.05). The soaking medium that most caused staining was red wine. Conclusion: Red wine was the drink that generated the highest staining in all the resins tested, vodka did not change color stability significantly, the alcoholic concentrations tested did not directly influence the ...

“…Discoloration of dental prostheses and restorations is attributed to either 31,32 : intrinsic factors related to heredity, age, and processing modes of these restorations, 33 or extrinsic factors derived mainly from colorants of food products such as caffeinecontaining beverages or mouth rinses, 34 which in turn adhere on restoration surfaces by 35 : physical and chemical electrostatic forces (van der Waals) and hydrophobic interdigitation.…”

Objectives:The present study aimed to comparatively evaluate the influence of oral rinse solutions and tooth brushing on stainability of thermoplastic tooth colored prosthetic materials, using computerized spectrophotometry before and after immersion. Materials and Methods:Fifty-six samples (Twenty-eight samples of each material); Acetal resin and polyether ether keton(PEEK) were constructed in the form of discs (10 mm in diameter and 2 mm in thickness). Samples were randomly divided into 4 subgroups (n=7) according to the oral rise solutions (chlorhexidine, benzydamine HCl, alcohol-free mouthwash) and artificial saliva as control. Simulated tooth brushing of samples for 4 min with rotary instruments was applied before immersion in mouth rinses. The mean of color values (L*,a*,b*) of each specimen were measured before and one week after exposure with a Reflective spectrophotometer.Results: regardless to staining solutions totally it was shown that Acetal resin material group recorded higher color change mean value (4.75±0.52 ∆E) than PEEK material group mean value (4.64±0.66 ∆E).The difference between both materials groups means values was statistically nonsignificant as indicated by two-way ANOVA (F=0.31, P=0.5748>0.05). On the other hand Listerine zero recorded the highest color change mean value (5.05±0.5 ∆E) followed by Tantum V solution mean value (4.91±0.37∆E) then CHX solution mean value (4.52±0.7 ∆E) while A. saliva solution recorded the lowest color change mean value (4.29±0.52 ∆E).Conclusions:1-There was a highly significant difference between alcohol free, benzydamine HCL & CHX mouth rinses. The listerine zero showed the highest value in staining potential while CHX was the lowest regarding acetal 2-Among the two thermoplastic restorative materials and although statisticaly non significant, PEEK was found to be the higher color stable material and the higher stain was taken up by acetal resin. 3-There were no significant differences between the discoloration effects of different mouth washes used in this study on PEEK material.
