Cheng YL, et al. - Authors estimated 48 specimens randomly divided into 2 groups (n = 24) viz, group B (bleaching with 40% hydrogen peroxide) and group C (control group without bleaching treatment) to ensure the outcome of surface removal after bleaching on the micro-shear bond strength (μSBS) of bleached enamel. They noted a range of the μSBS values of the different groups, 21.42 to 25.21 MPa. They found no significant impact of bleaching treatment and thermocycling on the μSBS values, following a surface reduction of 0.5 mm. They observed no significant interaction between bleaching treatment and thermocycling.
