The specimens were then randomly distributed into seven groups (n = 10), based on mouthwash used: five charcoal-based mouthwashes (Hello Activated Charcoal Extra Freshening Mouthwash, My Magic Mud Activated Charcoal Alcohol-Free Oral Rinse, Dr. Jones\u2019 Naturals Activated Charcoal Mouthwash, The Humble Co. Natural Mouthwash Charcoal, and Colgate Plax White + Charcoal), one hydrogen peroxide-based mouthwash (Crest 3D White), and artificial saliva. Each specimen was immersed in the relevant mouthwash for 60 seconds, rinsed with water for 30 seconds, and then immersed again in a fresh mouthwash solution for 60 seconds to simulate daily mouthwash use. This cycle was repeated to represent 1, 2, 3, 4, and 12 weeks of use. Color measurements were performed at baseline, after staining, and after 1, 2, 3, 4, and 12 weeks. Surface roughness was evaluated after staining and after 1, 2, 3, 4, and 12 weeks of immersion. The surface morphology of the specimens was examined using a scanning electron microscope.
