Clinical and patient reported outcomes of bleaching effectiveness

Objective was to evaluate clinical and patient reported outcomes of different bleaching products. Thirty participants were randomly divided into 3 bleaching groups (n=10). Bleaching was performed with high concentrations of hydrogen peroxide (HP) – Boost (40%) and Dash (30%), and with prefabricated splints Bite&White (6% HP). Tooth color was measured before, immediately after, and one and six months after the bleaching by using classical shade guide and spectrophotometer. Tooth hypersensitivity was self-rated by patients on the Wong-Baker’s face scale. Patient satisfaction was evaluated on a 7-point Likert-type scales that measured perceived performance and importance of different characteristics of bleaching treatment. All products were effective in teeth color change (ΔE>3.3), which was significantly higher for Boost (p=0.016) and Dash (p=0.024) than Bite&White treatment. Perception of hypersensitivity was the highest in Boost group, followed by Dash and Bite&White treatment. Most of the patients were satisfied with final tooth color, length and comfort during treatment, but were dissatisfied with the stability of bleached tooth color. Materials with the higher concentrations of bleaching agent demonstrated greater bleaching effectiveness than at-home bleaching product, but also a greater hypersensitivity. Lengthening the treatment process, but achieving a more stable tooth color may improve the perceived value of a bleaching service.
