Staining ability of herbal tea preparations on a nano-filled composite restorative material

One hundred and twelve discs were prepared from FiltekTM Z350XT composite Samples were divided into Green Tea Moringa Tea, Hibiscus Tea, and Artificial Saliva (AS) groups and immersed in freshly prepared beverages for 15 minutes each day for 45 days. Digital Reflectance Spectrophotometer was utilized to record color change and reported as ∆E Baseline, ∆E at 30 days, and ∆E at 45 days. Mean difference was calculated at 30 days (Mean difference of ∆E at 30 days = ∆E at 30 days - ∆E at baseline) and 45 days (Mean difference of ∆E at 45 days = ∆E at 45 days - ∆E at baseline).
