Abstract:

White spot lesions （WSLs） are defined as “subsurface enamel porosity from carious demineralization” which present as “a milky white opacity located on smooth surfaces”. Since bracket were bonded and introduced， WSLs have become a particular clinical problem that can be attributed to etching of the tooth and prolonged plaque accumulation on surfaces. Plaque control is the most effective preventive measure， while the use of infiltrantresin is currently the most popular treatment for WSLs due to the fixed orthodontic treatment with multi-brackets. This review was about white spots lesions on teeth in orthodontically treated patients.

Key words: fixed orthodontic treatment, multi-brackets, white spots lesion
