INFILTRATE
The affected teeth were isolated using a rubber dam (Royal Shield Powder Free Latex Dental Dams, Malaysia) and a clamp (YDM, Tokyo, Japan) before the application of Icon®. A sufficient amount of %15 hydrochloric acid was applied to the lesion using the Icon® etch syringe included in the set and was allowed to sit for 2 min. After washing it with water for 30 s, the tooth was dried using an air spray. Once the enamel surface appeared chalky, Icon® dry application was initiated.Ethanol was applied to the lesion using the Icon® dry syringe included in the set, and after 30 s, it was dried using an air spray. A sufficient amount of resin infiltrant was applied to the lesion using the Icon® infiltrant syringe. The resin infiltrant was applied to the lesion surface by massaging the tip of the syringe on the lesion in circular movements for 3 min, such that it penetrated the surface thoroughly. The resin infiltrant was polymerized for 40 s with a light-cure device (3 M ESPE Elipar S10, U.S.A.). Subsequently, the material was applied for the second time. One minute was provided for the material to infiltrate the pores, after which it was polymerized for 40 s. When the procedure was complete, the rubber dam and clamps were removed, and surface finishing was performed using fine-grained polishing burs and rubbers (Fig. Steps in Icon® application (
