Background: This study aimed to verify the effects of bleaching toothpaste on colour stability, elastic properties, surface topography between aesthetic polyurethane and silicone elastomeric ligatures from different brands.
Methods: Elastomeric ligatures tested were: 1-Mini Single Case Ligature Stick (RMO-polyurethane); 2-Ligature "S" Shaped Dispenser (RMO-Silicone); 3-Sany-tie (GAC-translucent polyurethane); and 4-Sili-tie (GAC-translucent silicone). The ligatures were randomly assigned from the brackets of canines and lower incisors of 40 patients.
