Aesthetic impact of resin infiltration and its mechanical effect on ceramic bonding for white spot lesions.

Background: Treating white spot lesions (WSLs) with resin infiltration alone may not be sufficient, raising questions about its compatibility with other treatments amid controversial or incomplete data. Therefore, this study aimed to assess the aesthetic feasibility of resin infiltration combined with bleaching, as well as its potential mechanical effect on ceramic bonding to WSLs.

Methods: One hundred and fifty flat enamel surfaces of bovine incisors were prepared.
