Objective: This study was done to investigate the effects of application of two different bleaching techniques and agents on enamel hardness and surface morphology. Material and methods: twenty six intact human first premolars extracted for orthodontic reasons were used in this split-tooth in vitro study. The specimens were randomly divided into two equal groups and sectioned buccolingually. Half of each crown was treated and the other half served as its control. For Group 1 (G1), an in-office… Expand
