Enamel demineralization during orthodontic treatment can be reversed with the proper remineralizing agent and protocol. NaF solution and N technology have different compositions and produce varying degrees of remineralization. Aim: Comparative Evaluation of remineralization potential of NaF solution and N technology on enamel remineralization. Material and methods: This in vitro study involved 106 freshly extracted premolar teeth, which were equally divided into two groups, group A treated with N technology paste and group B treated with NaF solution. The selected teeth were abraded, exposed to a carbonated drink (Thumbs Up) for 14 minutes daily for two weeks, and then air dried with deionized water for seven days. Teeth with poor demineralization or uneven lesions were excluded. Micro hardness was measured using Vicker's hardness scale, and surface topography was evaluated with a scanning electron microscope (SEM). Results: Intact enamel (normal enamel) and remineralized enamel was significantly harder than demineralized enamel, (p value is less than 0.00). There was no statistical difference in hardness between enamel remineralized with NaF solution and N technology (p value = 0.368). Both agents had conflicting effects on enamel surface topography. Conclusion: Both remineralization techniques effectively remineralized enamel. The type of agent used did not affect the hardness of the remineralized enamel. N technology produced a smoother enamel surface compared to NaF. However, caution is advised in interpreting these findings
