Resin Infiltration Versus Acid Micro-Abrasion In The Treatment Of Resin Infiltration Versus Acid Micro-Abrasion In The Treatment Of White Spot Lesions In Fixed Orthodontic Patients

Background: White spot lesions (WSls) are frequently occurring side effects of fixed orthodontic treatment. The lesions may progress to cavities. Their treatment is costly and time-consuming. Icon infiltrant and Opalustre are painless micro-invasive procedures that improve the color of the WSLs. Aim: The aim of this randomized clinical trial was to compare resin infiltration and acid micro-abrasion. Materials and Methods: Twelve patients, with ninety post-orthodontic white spot lesions, were randomly divided into two groups. Icon resin infiltrant was applied in one group and Opalustre acid micro-abrasion in the other. The caries score was measured with ICDAS-II. The patients recorded their satisfaction on a VAS scale. Wilcoxon signed-rank test compared the two groups and the Friedman test compared the outcomes over time. Results: Compared to the pre-treatment, the ICDAS-II scores statistically decreased immediately after treatment, after 3 months, and after 6 months, in both groups. Compared to pre-treatment, the patient satisfaction increased immediately after treatment, after 3 months, and after 6 months, in both groups. Conclusion: Icon and Opalustre improve the color of WSLs. Color is stable over time. Patients are satisfied with the treatment results
