Using resin infiltration to treat developmental defects of enamel: Three case reports

White spots or patches on permanent incisors are common among young adolescents; this may cause aesthetic concerns for both the patient and the parents equally. Management of developmental defects of enamel (DDE) is challenging and highly dependent on the type, severity, and appearance of the defect. Resin infiltration procedure is simple and conservative, and the procedure is generally well tolerated by patients. The material was introduced in the market to treat initial interproximal carious lesions and for post-orthodontic decalcifications. It was noticed that enamel lesions treated with resin infiltration would lose their whitish appearance as the microporosities are filled with the resin. In this case report, we have demonstrated the successful use of resin infiltration (ICON^® ) for masking the white color resulting from mild DDE. The pleasing aesthetic results and the conservative nature of this approach make it a good alternative to microabrasion and conventional resin restorations.
