Abstract

Objectives: Resin infiltration is an innovative approach for enhancing the esthetic appearance
of white spot lesions (WSLs). The aim of this study was to compare the effect of both resin infiltrant
(ICON) and adhesive resin with respect to esthetic improvement.
Methods: A randomized controlled split- mouth clinical trial was conducted on 10 young
adults with at least two non-cavitated white spot lesions in esthetic zones. They were randomly
assigned to two treatment groups: resin infiltrant (Icon, pre-product: DMG) or AdperTM single
bond 2 adhesive system (3M ESPG dental product, USA) application after 15% hydrochloric acid
(HCL) etching and dehydration with ethanol. Vita Easyshade V (Vita Zahnfabrik, Bad Sackingen,
Germany) spectrophotometer was used to measure the CIELAB coordinates and values were used
to calculate difference in color (ΔE). Data were tabulated and statistically analyzed using computer
software SPSS.
Results: There was a statistically significant decrease in both (ΔL) and (Δa) with increase in
(Δb) with ICON application (p<0.05). Regarding adhesive resin, there was a significant decrease in
both (ΔL) and (Δa) coordinates with non-significant change in (Δb). Also, there was a statistically
significant difference between ICON and adhesive resin regarding (ΔE).
Conclusions: Color change of white spot lesion treated with ICON and adhesive resin was
clinically obvious after treatment with hydrochloric acid. However, ICON reported significant
results in esthetic improvement in all color parameters.
