Staining is not unique to natural enamel and may also occur on the restorative material, such as conventional glass ionomer cement (GIC). This study identified the effect of whitening toothpaste on the discoloration level of conventional GIC. In total, 24 GIC specimens were immersed in coffee and then brushed with one of the four commercially available. The specimens were brushed for various durations (1, 2, and 4 weeks), and changes in discoloration were assessed using a digital colorimeter (VITA Easy Shade). Significant changes (p<0.05) in brightness were observed after the first and fourth week of brushing. However, not all toothpaste caused significant color changes. This study provides evidence that some whitening toothpaste can decrease the discoloration level of stained conventional GIC.
