Beverages effect on the fluorescence of different ceramic materials

Abstract

Aim: This study evaluated four beverages' impact on the intensity of fluorescence using three different ceramic materials. Methods: Three ceramic material brands were used; Lava Ultimate, Vita Enamic and Vita Block Mark II. These materials were cut in slices simulating veneers thickness using the isomet machine then were finished using a special kit. Twenty slices of each material were assigned into 4 groups according to the type of staining solution. The immersing solutions were coffee, tea, pepsi and distilled water as a control group. Fluorescence intensity was measured using a spectrofluorometer. All groups were held in an incubator for 30 days and were re-measured after immersion for fluorescence intensity. Results: Data were explored using Kolmogorov Smirnov and Shapiro-Wilk tests. Two-way ANOVA followed by Tukey's post-hoc test was used to compare different groups (P 0.05). The results revealed that there was a significant effect of coffee on all groups, followed by Pepsi, while tea had the least effect. As for the materials, Vita block mark II has shown the least change in fluorescence. Conclusion: The ceramic materials and beverages consumed have an impact on the ceramic veneer's final fluorescence intensity.
