Treatment of post-orthodontic white spot lesions by resin infiltration: a case series

Introduction: White spot lesions (WSLs) are the most common side effects found in orthodontically treated patients. Icon treatment has been reported to revert colorimetric alterations of WSLs and halt carious progression. Material and methods: Four young patients with post-orthodontic WSLs, who were treated with resin infiltration. Results: In all patients, existing WSLs were successfully treated by Icon resin application. Given the minimal substance loss due to the erosion infiltration procedure, all patients were extremely satisfied with the results, although some WSLs could still be seen. Conclusions: Our case series shows the capability of treating WSLs due to orthodontic treatment with Icon resin infiltration. Longer observation periods in studies with larger patient populations are needed to validate the clinical significance found in these case series.
