Aim: Analysis of masking potential of the resin infiltration technique with dental milestones guaranteed caries infiltration concept (DMG ICON) on nonpitted white spot lesions due to fluorosis in newly erupted permanent maxillary incisors for better esthetics and psychological wellbeing in children. Materials and methods: This prospective interventional study was conducted on 60 newly erupted maxillary central incisors with mild, nonpitted white spot lesions of fluorosis till grade IV of the Thylstrup and Fejerskov (TF) index. The resin infiltration technique with DMG ICON (DMG, Hamburg, Germany) was used to mask lesions along with the analysis for color change using Euclidean distance, i.e., the ΔE (Delta E) unit of the CIE L*a*b* color space formula where ΔE = (ΔL2 + Δa2+ Δb2)½ using the image-analyzing software. Data were analyzed statistically by the SPSS software. Results: Fifty-one tooth samples (85%) showed complete masking of white spot lesions of fluorosis postoperatively to resin infiltration with net ΔE values less than or equal to 3.7 whereas lesions in nine tooth samples (15%) were not masked completely with net ΔE > 3.7. Statistically highly significant results were obtained with the Wilcoxon signed-ranks test (p value < 0.001). Conclusion: The minimally invasive resin infiltration technique using DMG ICON is highly efficient and satisfactory for masking of nonpitted white spot lesions of dental fluorosis in newly erupted permanent central incisors as per the analysis for color change using the image-analyzing software. Clinical significance: The outcome of masked and blended white spot lesions of fluorosis with the sound enamel in the smile zone with the resin infiltration technique was found to be a child-friendly, noninvasive, single-sitting approach with stabilized results in follow-up visits.
