Effectiveness and satisfaction of home-based external bleaching

Hydrogen peroxide is the main ingredient in bleaching products (BP), and based on settings of reaction, can produce (per-)hydroxyl anions, superoxide other radicals. The radical-related oxidative mechanism trigger breakage molecular bonds enameller dentinal stains, while exact process not entirely grasped. Products as a consequence look less colorful. amount active component, likelihood BP interaction with discolorations, contact duration all affect effectiveness treatment. Effectiveness also depends number variables, including individual's age, type staining, treatments. A significant local adverse effects have been recorded over-the-counter items due to poorly fitted tray, adjuvants such binders, preservatives, flavors well low pH, coexisting gingivitis, abrasion, erosion. In cases coupled utilization tobacco excessive alcohol intake because users demonstrate lower levels hypersensitivity may be heavily influenced by positive cosmetic effects, they must particularly counseled against getting done combination has found pose elevated oral carcinoma risk. Overall, current literature relation between procedure efficacy patient satisfaction.
