Application of Icon® infiltrant for masking hypomineralization in the maxillary central incisor: a case report

ABSTRACT Materials that enhance aesthetics and function in dentistry have become increasingly common. The Icon® resin infiltrant (DMG Chemisch-Pharmazeutische Fabrik GmbH, Hamburg, Germany) was specifically developed for masking white spots on the enamel surface. Studies have shown that the aesthetic effect of Icon® remains intact for up to 6 months and undergoes minimal changes over 12 to 24 months. In molar-incisor hypomineralization, the spots may exhibit more pronounced chromatic alterations and compromise dental structure. Icon® emerges as an effective conservative alternative for masking these spots due to its high penetration capacity in the dental structure. This case report presents the application of this conservative approach to the maxillary right central incisor of a 24-year-old patient with moderate molar-incisor hypomineralization, dissatisfied with the appearance of hypomineralization in tooth 11. The procedure was performed following the protocol established by the manufacturer. The use of Icon® resin infiltrant provided satisfactory masking of the MIH spot, restoring the tooth’s aesthetics and meeting the patient’s preference for a minimally invasive procedure, without the need for tooth reduction for direct or indirect restorations.
