Enamel Damages Following De-bracketing From Infiltrated Surfaces

Demineralisation and white-spot caries often occures during MB treatment. While resin infiltration has been proved to stop progression of enamel demineralisation, there is still a paucity of information in the literature concerning the best time point of infiltration: During or following MB treatment. Infiltration during treatment requires debonding respective brackets prior to infiltration, with subsequent re-bonding. In terms of preventing enamel damages by progression of demineralisation and enamel damages by de-bonding, it is unclear whether it was better to infiltrate enamel immediately, or to better postpone until completion of MB treatment. This study thus aimes to evaluate if resin infiltration can prevent enamel damage due to bracket de-bonding.
