ABSTRACT

Objective: To compare the staining intensity of turmeric and chewable tobacco with that of coffee and to investigate the impact of staining status on the bleaching efficacy of discolored restorative materials. Study Design: A total of 72 specimens from two types of dental composites (nanocomposite, and microhybrid composite) and two types of glass ionomer cements (conventional glass ionomers, and resin-modified glass ionomers) were immersed in different staining media including turmeric, coffee, and chewable tobacco (3 Hour/day). The color changes were measured at 15th, 30th, and 45th days of staining according to the CIELAB system. The discolored specimens were then bleached using a 10% carbamide peroxide solution (2×30 min daily) and the color changes were quantified after 7 and 14 days of bleaching. The obtained data were further analysed using ANOVA with complementary Tukey's test (p<0.05). Results and Conclusion: Chewable tobacco displayed the most overall staining effect on the selected materials, followed by coffee and turmeric. Nanocomposites showed the highest vulnerability to color change due to the exposure to coffee and turmeric, while the highest color change by chewable tobacco was observed in the resin-modified glass ionomers. In contrast, the conventional glass ionomers were least stained in all staining solutions. Carbamide peroxide also exhibited more bleaching effect on nanocomposites compared to other selected restorative materials. Clinical Significance: Conventional glass ionomers and microhybrid composites are more suitable compared to resin-modified glass ionomers and nanocomposites for utilization in places where esthetic longevity is the prime concern (anterior teeth and premolars in smile line) and patient has high intake of coffee, turmeric, or chewable tobacco.
