Objectives: This study was carried out to evaluate the effect of a resin infiltrant in changing
the color of white spot lesion clinically, in addition to the color stability of the treated lesion over
one year period.
Methods: Fifteen post-orthodontic treated patients. For each patient the white spot lesion
was treated with resin infiltrant system (Icon). Assessment of color was done using digital clinical
photography before, immediately after the treatment, after 6 months and after 12 months.
Results: Icon resin infiltrant showed statistically significant change in mean (ΔE) immediately
after treatment, after 6 months, and after 12 months.
Conclusions: Icon resin infiltrant is effective in changing the color of white spot lesion.
