Abstract
Background/purpose: During pandemic (Covid19) Adults frequently increase vitamin C syrups and effervescent tablets intake for dietary support, The purpose of this study was to see how the different forms of Vitamin C syrup and effervescent tablets affected the color stability of two newly marketing esthetic restorative materials (Filtek bulk fill) resin composite and Resin Modified glass ionomer (Medifil IX forte LC). Materials and methods: A total of 90 disc-shaped specimens, 45 from each restorative material. The specimens were papered and randomly divided into six subgroups according to the immersion media of vitamin C either syrup (HIC Stars (FUTURE HERBALS, Nutra-C, USA),or effervescent tablet (Sanotact, Germany) and distilled water (control group), each contains 15 samples. The samples were immersed in 2 vitamins C for 2 min once a day for 28 days. Color stabilities measurements were recorded at baseline before immersion and on the 28th days after immersion. Color stability was measured using a spectrophotometer. Using CIELAB. ΔE Data was processed using statistical of Kruskal Wallis test and Mann Whitney U test. Results: There was a significant difference in the change of composite color when immersed in the three different solutions (p=0.010). Composite showed significantly less change in color when immersed in effervescent (4.8 ± 1.5) compared to water (6.7 ± 1.5). There was also a significant difference of color change of RMGI when immersed in the different solutions (p<0.001). RMGI immersed in effervescent showed significantly higher mean change in color (4.0 ± 2.6) compared to the mean change in color of RMGI when immersed in syrup (1.1 ± 2.5) or water (0.9 ± 1.1). Conclusion: The usage of different forms of vitamin C syrups and effervescent tablets for 28 days have a negative impact on the color stability of (Filtek bulk fill) resin composite and Resin Modified glass ionomer (Medifil IX forte LC).
