Abstract
Objectives: Resin infiltration is an innovative approach for enhancing the esthetic appearanceof 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 youngadults with at least two non-cavitated white spot lesions in esthetic zones. They were randomlyassigned to two treatment groups: resin infiltrant (Icon, pre-product: DMG) or AdperTM singlebond 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 usedto calculate difference in color (ΔE). Data were tabulated and statistically analyzed using computersoftware 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 inboth (ΔL) and (Δa) coordinates with non-significant change in (Δb). Also, there was a statisticallysignificant difference between ICON and adhesive resin regarding (ΔE).Conclusions: Color change of white spot lesion treated with ICON and adhesive resin wasclinically obvious after treatment with hydrochloric acid. However, ICON reported significantresults in esthetic improvement in all color parameters.
