The aim of this study was to evaluate the changes in opacities by applying resin infiltrate to developmental enamel opacities and applying resin infiltrate or fluoride varnish to white spot lesions (WSLs).

Materials and Methods:

A total of 132 teeth with WSLs and developmental enamel opacities were included in the study. WSLs were treated with resin infiltrate (Group 1) and fluoride varnish (Group 2), and developmental enamel opacities were treated with only resin infiltrate (Group 3). Lesions were evaluated in accordance with International Caries Detection and Assessment System (ICDAS II) criteria and DIAGNOdent Pen scores before applying the material (T0), just after the application (T1), and after 1 month (T2) and 3 months (T3).


A significant decrease in DIAGNOdent Pen scores was observed in all the groups and the most important decrease was seen in Group 2 (P < 0.05). A significant decrease in ICDAS II scores was observed in Groups 2 and 3 (T0-T1) and Group 1 (T1-T2) (P < 0.05).


DIAGNOdent pen scores decreased and the lesion was partially masked after resin infiltrate was applied to treat developmental enamel opacities; the resin infiltrate application, however, was more successful than fluoride varnish on WSLs. Treating WSLs with resin infiltrate was a good option due to shorter term esthetic recovery and high patient satisfaction.
