“…Therefore, Filtek Z250, Filtek Supreme, and Premise exhibited less surface hardness change with no significant differences among them than did Compoglass F at each immersion period. This was because the citric acid found in the sports and energy drinks affected the solubility of compomer Compoglass F more than the other resin composites 17,30) . Among the examined sports and energy drinks, Burn -with the lowest pH at 2.67-had the greatest surface hardness reduction effect on the restorative materials tested.…”

“…To be clinically successful, dental composites must be durable and have a high degree of wear resistance in the oral cavity 13,14) . They are exposed either intermittently or continuously to chemical agents found in saliva, food, and beverages [15][16][17] -and such exposure can soften the resin matrix of the composite resins and cause filler constituents to leach out 18) . Surface hardness is an important indicator of a restorative material's mechanical strength and resistance against intra-oral softening 4,19) .…”

The purpose of this study was to evaluate the effect of sports and energy drinks on the surface hardness of different restorative materials over a 6-month period. Forty-two disk-shaped specimens were prepared for each of the four restorative materials tested: Compoglass F, Filtek Z250, Filtek Supreme, and Premise. Specimens were immersed for 2 min daily, up to 6 months, in six storage solutions (n=7 per material for each solution): distilled water, Powerade, Gatorade, X-IR, Burn, and Red Bull. Surface hardness was measured at baseline, after 1 week, 1 month, and 6 months. Data were analyzed statistically using repeated measures ANOVA followed by the Bonferroni test for multiple comparisons (α=0.05). Surface hardness of the restorative materials was significantly affected by both immersion solution and immersion period (p<0.001). All tested solutions induced significant reduction in surface hardness of the restorative materials over a 6-month immersion period.

“…Thus, the surface characteristics of a resin composite contribute to the clinical longevity of a restoration 12 . Although a number of studies have addressed the effects of different solutions on the surface of resin composites [13][14][15] , few have performed longterm evaluations. Thus, the aim of the present study was to evaluate the surface roughness (Ra) of a resin composite submitted to immersion in different beverages one hour per day for three, six, nine and 12 months.…”

ObjectiveThe aim of the present study was to evaluate the surface roughness (Ra) of the Z-350 resin composite following immersion in different media (distilled water, coca-cola, coffee, black tea and red wine). Methods Fifty Results A significant increase in Ra was found in the specimens submitted to coffee, coca-cola ® and black tea between baseline and the three-month evaluation. Variance was also found among the remaining evaluation times (3 months to 12 months), but the differences did not achieve statistical significance. No statistically significant differences in Ra were found among evaluation times in the specimens submitted to red wine or distilled water. ConclusionBased on the present findings, coca-cola, coffee and black tea exert an influence on the surface roughness of resin composites. RESUMO ObjetivoAvaliar a rugosidade da superfície (Ra) do Z-350 resina composta após imersão em diferentes meios (água destilada, coca-cola, café, chá preto e vinho tinto). MétodosForam preparados cinquenta espécimes de resina composta medindo 10 mm x 2 mm. A polimerização foi realizada através do método convencional (40 s). Cada espécime foi imerso durante uma hora por dia. As avaliações foram realizadas na linha de base, bem como após três, seis, nove e 12 meses. Três leituras Ra foram levados em direções opostas em cada avaliação, utilizando um medidor de rugosidade. Os valores médios de Ra foram submetidos a análise de variância (ANOVA) seguido pelo teste de Tukey (p <0,05). ResultadosUm aumento significativo na Ra foi encontrada nas amostras submetidas ao café, coca-Cola ® e chá preto entre o início e a avaliação de três meses. Variância também foi encontrado entre as épocas de avaliação restantes (3 meses a 12 meses), mas as diferenças não atingiram significância estatística. Não houve diferenças estatisticamente significativas na Ra encontrados entre os momentos de avaliação nos casos submetidos ao vinho tinto ou água destilada. ConclusãoCom base nos achados, coca-cola, café e chá preto exercem uma influência sobre a rugosidade superficial de resinas compostas.Termos de indexação: Bebidas. Imersão. Resinas compostas.

Resin‐modified glass ionomer enriched with BIOGLASS: Ion‐release, bioactivity and antibacterial effect

et al. 2022

Developing dental materials for the prevention of remineralization or demineralization is important for high‐risk caries patients. This study aimed to evaluate the physicochemical and microbiological effects of adding 45S5 bioglass to resin‐modified glass ionomer cement (RMGIC). Samples belonged to the following groups: GIC: conventional glass ionomer cement (Vitro Fil), RMGIC: resin‐modified GIC (Vitro Fil LC), and RMGIC/45S5: RMGIC with 10% (wt %) of 45S5. Changes in pH and release of fluoride, calcium, and phosphorus ions under acidic (pH 4) and neutral (pH 7) pH conditions were evaluated. Antibacterial activity was verified based on colony‐forming units. Material sorption and solubility were analyzed after bacterial exposure. After 28 days, the bioactivity of the materials was evaluated using scanning electron microscopy/energy dispersive X‐ray spectroscopy (SEM/EDS). Analysis of variance, post hoc Scheffe, and Tukey (α = 0.05) tests were employed for statistical analysis. RMGIC/45S5 showed higher alkalization activity, calcium release at pH 4 and 7, and sorption than GIC and RMGIC (p < .05). Release of phosphorus and fluoride at pH 4 and 7 was higher for GIC than that for RMGIC and RMGIC/45S5 (p < .05). RMGIC/45S5 showed higher values than RMGIC (p < .05). However, antibacterial activity did not differ among the groups. Precipitates of calcium and phosphorus were visualized in RMGIC/45S5 samples via SEM/EDS. These results indicate that the RMGIC/45S5 promotes alkalization and increases the release of calcium, phosphorus, and fluoride ions, resulting in precipitate deposition rich in calcium and phosphorus, thereby being a promising option to improve the bioactivity of RMGIC.

Effects of Various Beverages on Hardness, Roughness, and Solubility of Esthetic Restorative Materials

Abstract: Low pH beverages were the most aggressive media for glass ionomers and compomer, by contrast, composite resin was relatively less affected. Water and natural milk appeared relatively benign towards the tested materials.
