Listerine Whitening and Colgate Plax Whitening are mouthwashes, Whiteness Perfect 10% is a CP gel, and Bromelain + papain is an experimental mouth rinse formulated as a control. Whiteness perfect gel was applied over the enamel surfaces, and left on the surface of the teeth for a total of eight hours. Next the gel was removed and the specimens were submitted into the dye-rinse cycle. For the dye- rinse cycles the incisors were immersed for five minutes in the staining broth. Next the specimens were immersed for the two minutes in the mouth rinses and finally placed in a sample of artificial saliva. This cycle was repeated for a total of 12 weeks, and the color reading was obtained after ever few weeks. The purpose of allowing the specimens to remain in the broth for five minutes was to imitate the extreme situations of the daily consumptions of food dyes. The result from this study showed that Listerine Whitening and Plax Whitening were able to maintain the results obtained initially with 10% CP, for a stimulated three-month period of the dye rinse challenge (Oliveira et al., 2017). Additionally, out of the specimens solely submitted to the mouth rinse treatment Listerine Whitening and Plax Whitening had shown the best whitening result.

If the mouthwash is to acidic it can cause the shade of the teeth to become darker over time. Another factor that researchers has stated that can affect the whitening effect of whitening mouthwashes is the exposure time. The use of Whitening mouth rinses is recent and few studies on this topic are available (Oliveira et al., 2017). Additionally, manufactures conduct their own evaluations or fund researchers to test their product. Thus, there is no need to conduct independent studies using commercially available products to learn the action and possible side effects of mouth rinses and other over the counter bleaching products (Lima et al., 2012). More clinical trials are needed so that researchers can ensure the effectiveness of whitening mouth rinses, and determine the best protocol to use
