The objective was to determine if the resin infiltration approach could protect demineralized enamel surface from acidic pH. Materials and methods: For the investigation, 30 healthy upper and lower premolars were chosen, and each was cut vertically into two halves, yielding 60 specimens. The specimens were subsequently split into three groups, with group A serving as the control group, groups B underwent decalcification alone and group C underwent decalcification followed by Icon resin infiltration. According on the kind of storage media, each group was further separated into three subgroups (water, pepsi or sprite ). Surface topography, surface roughness, and colour difference were among the evaluation criteria. One-way ANOVA test was used for statistical analysis. Results: Even though Pepsi generated the most surface roughness and colour change among the specimens under study, enamel that had resin treated had higher resistance to surface alterations than enamel that were not resin treated. Conclusion: Even on acidic challenge, resin infiltration has the capacity to offer and maintain protection against demineralized enamel.
