BACKGROUND: Resin infiltration proved to be effective
on enamel hypomineralized lesion of various etiologies, as
described by Paris et al. White spot post orthodontic lesions,
early enamel carious lesion, developmental defects of enamel
and mild fluorosis can be treated with good prognosis by
Iconâ. On the other hand, when a deeper configuration of
the lesion is found, as in severe fluorosis and post-traumatic
lesions, an experimental approach has been described by Attal
et al. The aim of this study was to present the clinical report

BACKGROUND: Iconâ proved to be effective on enamel
hypomineralized lesion with white demarcated and diffuse
clourimetric alteration, such as White Spot Lesion (WSL),
Developmental Defects of Enamel (DDE) and mild cases of
Fluorosis (1) (2) (3) (4)on the buccal side of aesthetic tooth.
Resin infiltration treatment increases the Refractive Index (RI)
of demineralized enamel. Paris et al. described the rising of
RI on infiltrated lesions, that took on the appearance of the
sound surrounding enamel (5). On the other hand, lesions with

Introduction: Severe Enamel Fluorosis is frequently found in young adolescents with aesthetic concerns. Colourimetric alterations could vary from diffuse opacities to demarcated brown and white areas. Material and methods: One young patient with a severe fluorosis was treated by a combined use of at-home bleaching and at-office resin infiltration. Results: In all the affected teeth, existing aesthetic enamel alterations, were successfully treated by the combined use of bleaching and Icon® resin application.

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
