ABSTRACT Objective To study the effect of three energy drinks on the color stability of nanofilled composite resins after different periods of aging time. Materials and methods Composite resin disks, 6 mm diameter, 3 mm thickness were prepared from Filtec Z350 XT, Tetric EvoCeram, and Filtec Z250 XT. Specimens from each material were tested after aging with Red Bull, Bison and Power Horse energy drinks and distilled water as a control. Specimens were stored at 37°C in dark containers for 1, 7, 30 and 60 days. Color was assessed in the CIELAB using a colorimeter before and after each storage period. Color differences ΔE*ab and Δb* among specimens were measured. Mean values were statistically analyzed using one-way analysis of variance (ANOVA), with p < 0.05 as significance level. Results The color change ΔE*ab and Δb* occurred by Red Bull, Bison and Power Horse energy drinks was significantly different for all tested materials at all four times p < 0.05 except in the Red Bull group. All specimens showed increase in color changes toward yellowness Δb* after a period of 1, 7, 30 and 60 days. The highest total color difference ΔE*ab was found in the Red Bull group after 60 days. Conclusion Energy drinks used in this study had staining effect on the tested composite resin materials. The discoloration increased with aging time toward yellowness; however, it was not perceptible in all test groups after 60 days. How to cite this article Al-Dharrab A.

ABSTRACT Objective To study the effect of three energy drinks on the surface roughness of nanofilled composite resins after different periods of aging time. Materials and methods Composite resin disks, 6 mm diameter, 3 mm thickness were prepared from Filtec Z350 XT, Tetric EvoCeram and Filtec Z250 XT. Specimens fr/8om each material were tested after aging with Red Bull, Bison and Power Horse energy drinks and distilled water as a control. Specimens were stored at 37°C in dark containers for 1, 3 and 6 months. Surface roughness Ra was assessed using a surface scanning interferometry before and after each storage period. Surface roughness differences ΔRa and Ra among specimens were measured. Mean values were statistically analyzed using multiple repeated measured (ANOVA), variance and multiple comparisons of the mean values were done with Bonferroni test, with p < 0.05 as significance level. Results The surface roughness degradation change ?Ra and Ra value before and after occurred by Red Bull, Bison and Power Horse energy drinks was significantly different for all tested materials at all three times p < 0.05. All specimens showed increase in surface roughness changes after aging periods of 1, 3 and 6 months. The highest total surface roughness difference ΔRa and Ra was found in the Red Bull group after 6 months. Conclusion Energy drinks used in this study had surface degradation effect on the tested composite resin materials. The surface roughness increased with aging time however, it was clinically acceptable in all test groups after 6 months. The effect of energy drinks solutions on the surface roughness parameter of resin composites depends on type of solution and its acidity contents. How to cite this article Al-Samadani KH.

ABSTRACT Introduction To evaluate the effects of energy drinks on glass ionomers (GI) restorative materials color stability after different periods of aging time. Materials and methods Glass ionomers disks, 8 mm diameter, 3 mm thickness within Teflon beverages are Code Red, Red Bull, and Power Horse. Specimens were tested for aging in beverages (Code Red, Red Bull, and Power Horse). The distilled water was used as a control. The variations in color were evaluated in the CIELAB [CIE L*a*b* (CIELAB) is a color space specified by Commission International de Eclairage (CIE)] using a colorimeter pre- and post-storage period. Color differences (ÄE*ab, Äb*) in each specimen were recorded. The t-test analysis was performed (p < 0.05 was considered as significant). Results The color changes by Code Red, Red Bull, and Power Horse energy drinks were significantly different for all tested materials (p < 0.05). Each specimen exhibited total color changes toward yellowness, after a period of 1, 7, and 30 days. The greatest color difference (ÄE*ab) was observed in the case of Red Bull group following 1 week. Conclusion The energy beverages affected the color stability of tested GI restorative materials with the increase of aging time. The effect on the color stability of GI was influenced by factors, such as the type of solution and the presence of the acids causing erosion. Clinical significance Glass ionomer is used as cosmetic filling material. Energy beverages have erosive effect on glass ionomer which influences clinical importance by influencing on mastication and TMJ problem. How to cite this article Al-Samadani KH.

Abstract Objective The aim of study was to evaluate in vitro the surface hardness, sorption, solubility, and color stability of three light-cured resin cements, namely RelyX Veneer (RLX), Variolink Veneer (VLK), and All Cem Veneer (ACV). Materials and Methods Cylindrical samples (15 × 1 mm) were made for each group using a metallic mold (n = 10). Vickers microhardness test was performed, and average hardness was calculated from three indentations (300 gf/15s) per sample. The sorption and solubility of the materials were evaluated according to ISO 4049:2009 based on three samples weighing: initial (m 1), after immersion in distilled water for 7 days (m 2), and final (after removal of all moisture [m 3]). The color change was observed using a digital spectrophotometer, at three different time points, baseline, 1 day, and 1 week of immersion in coffee and distilled water (control). Statistical Analysis Shapiro–Wilk test was used to analyze the normality of the data, and groups were compared using Kruskal–Wallis and Mann–Whitney tests. A significance level of 5% was used. Results RLX showed the highest microhardness mean values (36.96 VHN), but higher sorption (23.2 µg/mm3) and solubility (2.40 µg/mm3), with statistically significant differences with the other groups. For color stability, higher ∆E was observed for the samples immersed in coffee (p = 0.009). The VLK resin cement presented statistically significant differences from the other groups, with higher color changes in coffee at 1 day (15.14) and after 1 week (23.65). Conclusion RLX resin cement showed better hardness results. All materials tested performed satisfactorily for sorption and solubility according to ISO 4049:2009. All materials showed high-staining values after 1 week of immersion in coffee.

The purpose of this study was to evaluate, in vitro, the color stability of three composite resins of two different shades (A3 and C3) cured with either a quartz tungsten halogen (QTH) or a light emitting diode (LED) source. Forty specimens (20 x 2 mm) were prepared for each composite (Tetric Ceram®, Heliomolar® and Esthet-X®), being 20 for each shade. In each group, 10 specimens were light-cured using the QTH unit and 10 with the LED source. The shade of the materials was evaluated before and after submitting the specimens to artificial accelerated aging (4 h UV-B/4 h condensing vapor), using a reflection spectrophotometer. deltaE means were calculated and analyzed statistically by 2-way ANOVA and Tukey's test at 5% significance level. Both A3 and C3 shades of Esthet-X composite resin showed the lowest color change when cured with the QTH light, while Tetric C3 cured with the QTH light showed the highest color change.

We aimed to evaluate the color stability of bulk-fill and conventional composite resin with respect to thickness and storage media. Twenty specimens of a conventional composite resin (6 mm diameter and 2 mm thick) and 40 specimens of the bulk-fill Tetric EvoCeram composite resin at two different thicknesses (6 mm diameter and 2 mm thick or 4 mm thick,n=20) were prepared. The specimens were stored in distilled water during the study period (28 d). Half of the specimens were remained in distilled water and the other half were immersed in coffee solution 20 min/d and kept in distilled water between the cycles. Color changes (ΔE) were measured using the CIEL⁎a⁎b⁎color space and a digital imaging system at 1, 7, 14, and 28 days of storage. Data were analyzed using Two-way ANOVA and Tukey’s HSD post hoc test (P<0.05). Composite resins showed significant increase in color changes by time (bulk-fill > conventional;P<0.001). Coffee exhibited significantly more staining susceptibility than that of distilled water (P<0.001). There was greater color changes with increasing the increment thickness, which was significant at 14 (P<0.001) and 28 d (P<0.01). Color change of bulk-fill composite resin was greater than that of the conventional one after coffee staining and is also a function of increment thicknesses.

AbstractDespite composite resins capacity to mimic dental tissues, they can discolor over time. However, there is no information on the effect of prebrushing mouthwashes on the composite resin staining. This study aimed to evaluate the effect of prebrushing mouthwashes on the color stability of three composite resins. Twenty specimens of each resin were prepared: Filtek Z250 (3M ESPE –S Paul, MN, USA), Charisma (Heraeus Kulzer GmbH - Hanau - Germany) e EvoluX (Dentsply- Petrópolis - Brazil). Groups were randomly divided accord to the treatment: immersion in prebrushing mouthwash (test group) or immersion in deionized water (control group). Test groups were immersed in 10 ml of prebrushing mouthwash Plax Magic (Colgate-Palmolive, São Bernardo do Campo, SP, Brazil) for 60 s three times a day during 35 days following the manufacturer’s instructions. Color measurements were performed after 24 h of specimen’s preparation and after 7, 14, 21, and 35 days of immersion time. Results showed that prebrushing mouthwash Plax Magic promoted a color change in all the tested materials and evaluation time. The color change was greater in composite resin Charisma, followed by Z250 and EvoluX. Therefore, prebrushing mouthwash promoted a color change in all the materials used. Composite resin Charisma demonstrated less color stability than Filtek Z250 resin and EvoluX resin, which was the most stable.Keywords: Composite Resins. Oral Hygiene. Color.ResumoApesar da capacidade das resinas compostas de mimetizar os tecidos dentais, esses materiais podem ter sua cor alterada com o tempo. No entanto, não há informação na literatura sobre o efeito de evidenciadores de placa na estabilidade de cor desses materiais. Este estudo teve por objetivo avaliar o efeito de um evidenciador de placa na estabilidade de cor e três resinas compostas. Para isso, 20 espécimes de cada resina foram preparados: Filtek Z250 (3M ESPE –S Paul, MN, EUA), Charisma (Heraeus Kulzer GmbH - Hanau - Alemanha) e EvoluX (Dentsply- Petrópolis - Brasil). Os grupos foram aleatoriamente divididos de acordo com o tratamento a ser submetido: imersão no evidenciador de placa (grupo teste) ou imersão em água deionizada (grupo controle). Os grupos teste foram imersos em 10 ml do evidenciador de placa Plax Magic (Colgate-Palmolive, São Bernardo do Campo, SP, Brasil) por 60 s três vezes por dia durante 35 dias, de acordo com a orientações de uso do fabricante. As leituras de cor foram feitas após 24 h da preparação dos espécimes e após 7, 14, 21 e 35 dias de imersão. Os resultados mostraram que o evidenciador de placa Plax Magic promoveu alteração de cor em todos os materiais usados e em todos os tempos de leitura. A alteração de cor foi maior na resina Charisma, seguida da Z250 e EvoluX. Portanto, o evidenciador de placa promove alteração de cor em todos os materiais testados. A resina composta Charisma demonstrou menor estabilidade de cor que as resinas Z250 e EvoluX, que, por sua vez, foi a mais estável. Palavras-chave: Resinas Compostas. Higiene Oral. Cor.

Objective: To evaluate the color stability of Tetric® N-Ceram Bulk Fill composite restorative material after immersion in three different (energy drink, protein supplement solution, and combination of energy drink and protein supplement solution) drinks. Materials and Methods: Composite resin disks, 2 mm in depth and 5 mm in diameter, were prepared from the Tetric® N-Ceram Bulk Fill composite restorative material. Specimens were tested after immersion and aging in energy drink (Red Bull) alone, protein supplement solution alone, and in combination with energy drink and protein supplement. Deionized water was used as a control group. Specimens were stored at room temperature of ±23°C for a period of one week in each drink. Color was assessed in the CIELAB using Color Eye 7000A Spectrophotometer. Color differences in different group specimens were measured. Mean values were statistically analyzed using one-way analysis of variance (ANOVA). Further Tukey’s multiple comparison tests were applied to know the differences between the group of specimens. A p value of p < 0.05 was set as significance level. Results: N-Ceram Bulk Fill composite showed Δ L, Δ a, Δ b, and Δ E mean and standard deviation values when immersed in deionized water (–2.6 ± 3.24, 0.16 ± 0.19, 0.32 ± 1.26, and 3.51 ± 2.47), energy drink (–4.19 ± 4.24, 0.21 ± 0.21, 1.57 ± 1.32, and 5.40 ± 3.11), protein supplement (62.71 ± 12.48, –2.63 ± 0.7, 7.7 ± 5.67, and 63.45 ± 12.56), combined energy drink and protein supplement (68.52 ± 13.43, –4.06 ± 1.73, 10.94 ± 5.31, and 69.71 ± 13.42), respectively. All the color coordinates (Δ L, Δ a, and Δ b) showed statistically significant difference, p < 0.001. The color change of N-Ceram Bulk Fill composite specimens Δ E occurred by immersion in energy drink, protein supplement solution, and combined solution of energy drink and protein supplement after seven days was found to be statistically significant p < 0.001. Conclusion: The study’s finding suggests that the energy drink (Red Bull), protein supplement (ISOPURE), and combined immersion in energy drink and protein supplements caused perceptible and clinically unacceptable color change in the Tetric® N-Ceram Bulk Fill composite material. This color change was remarkably high with a combined immersion in energy drink and protein supplement solution.

<p><strong>Objective: </strong>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. <strong>Material and Methods: </strong>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. <strong>Results: </strong>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 &lt; 0.01) and in red wine (p &lt; 0.01), but not in vodka (p &gt; 0.05). The soaking medium that most caused staining was red wine. <strong>Conclusion: </strong>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 color change and the composite resin Grandio®So presented greater color stability when exposed to red wine.</p><p> </p><p><strong>Keywords</strong></p><p>Alcoholic beverage; Color; Composite resin.</p><p> </p><p>KEY WORDS: Alcoholic beverage, color, composite resin.</p>
