Aim: To compare the efficacy of Icon resin infiltration and Clinpro XT varnish on microhardness, surface roughness, and penetration depth of methylene blue dye of artificially induced white spot lesions (WSL). Materials and methods: Artificial WSLs were created on a sample of 45 extracted human premolar teeth by immersing in a demineralizing solution. All samples were randomly allocated to three divisions of 15 each for evaluation of microhardness, surface roughness, and penetration depth, where group I being the control, group II is Icon resin infiltration, and group III is Clinpro XT varnish. Assessment of microhardness, surface roughness, and penetration depth of dye were done with Vickers hardness tester, atomic force microscope, and stereomicroscope, respectively. The data obtained were analyzed using Statistical Package for the Social Sciences (SPSS) software. One-way analysis of variance (ANOVA) followed by the Bonferroni multiple comparison test was applied for comparing the mean microhardness and surface roughness among three groups. The Kruskal–Wallis test followed by Bonferroni–Dunn test was applied for comparing the median penetration depth. Results: The mean microhardness and standard deviation (SD) of groups I, II, and III showed 109 ± 16.21, 203.80 ± 22.19, and 129.80 ± 27.73, respectively. Mean surface roughness (Ra) and SD of groups I, II, and III showed 217.5 ± 8.78, 28.3 ± 9.7, and 165.8 ± 13.9, respectively. The median penetration depth of dye of groups I, II, and III showed 547, 63, and 71.0, respectively. These groups demonstrated a statistically significant difference with a p-value < 0.05. Conclusion: Icon resin infiltration has shown superior microhardness, lowest surface roughness, and lower depth of penetration of dye, followed by Clinpro XT varnish group. Clinical significance: Resin infiltration may be considered a promising solution not only to restore esthetics of WSL but also to stop the progress of dental caries by occluding the pores.
