🛑Bleaching Materials 🌸Hydrogen peroxide: Superoxol (30-35%) is the most common bleaching agent 🌟Sodium perborate: Sodium perborate: It is a material that when dry is stable but in the presence of water it decomposes to form sodium metaborate, hydrogen peroxide and oxygen. It is safe and easily controlled so it is used in intracoronal bleaching. 💫Carbamide peroxide: hydrogen peroxide (3-45%). It is mostly used in 10% and when it breaks down it forms about 3.5% hydrogen peroxide and many by-products as urea, ammonia carbon dioxide. مهم مهم المتيرل
