Objective: To analyse the staining properties of clear orthodontic brackets using a digital analysis.
Design: In vitro, laboratory study
Material And Methods: A total of 500 tooth-coloured brackets from 10 brands (five ceramic and five plastic) were investigated. The cumulative discolouring effect of staining agents (tea, coffee, curry and red wine) were analysed at two consumption levels: light and heavy, based on a 6-month period of exposure.
