The effectiveness of medical treatments depends on thorough knowledge of materials and techniques used. This is especially important in dentistry due to rich blood supply and the importance of the area in the patient’s psyche. Corrosion resistance is an important feature of all metal appliances used in dental care. We tested the corrosion resistance of metal brackets using a galvanostat and three artificial saliva solutions, formulated to have different pH levels. The results show that the maximum strength is obtained at pH values close to neutral.
