Efeito do açaí sobre a estabilidade de cor e rugosidade de um ionômero: estudo in vitro
Açaí can change the properties of glass ionomer cement with consequent early change of material. Aim: To evaluate the effect of açaí on the color variation and roughness of a resin-modified glass ionomer cement (CIVmr). Design: Seventy-five Vitremer discs (2 mm high, 8 mm in diameter) were divided i...

| Sumario: | Açaí can change the properties of glass ionomer cement with consequent early change of material. Aim: To evaluate the effect of açaí on the color variation and roughness of a resin-modified glass ionomer cement (CIVmr). Design: Seventy-five Vitremer discs (2 mm high, 8 mm in diameter) were divided into 3 experimental groups (n = 25): artificial saliva, sorbet and açaí juice. They were immersed in 6 mL of the solution for 15 min, 3x / day (30 min interval) for 14 days. The roughness variation (ΔR) and the color change (ΔE) (CIELAB) analyzed before and after immersion. Statistical analysis: ΔR was submitted to ANOVA 1 criterion on ranks, followed by the Bonferroni post-test. For ΔE the ANOVA 1 criterion was applied, followed by the Tukey post-test. Results: Absence of statistical difference between all groups (p = 0.666) for the variable ΔR. There was a statistically significant difference for ΔE between the artificial saliva and juice groups (p = 0.002) and between juice and sorbet (p = 0.019). Conclusions: The sorbet and açaí juice did not change the roughness of the CIVmr. All means caused clinically unacceptable staining, greater for the juice. |
