Minimally invasive management of hypomineralization with infiltrant resin

Abstract

Introduction: Vestibular hypomineralization on central incisors is a common clinical challenge for pediatric dentists. It is characterized by porous enamel with white or yellow-brown opacities, resulting from disturbances during the enamel mineralization phase. Hypomineralized enamel is more fragile, has lower resistance, increased sensitivity, and a higher risk of caries. In recent years, infiltrant resins such as ICON have been proposed as a minimally invasive option to mask these lesions and mechanically reinforce the enamel, thereby improving esthetics without the need for tissue removal. Case Reports: This report presents two pediatric patients with vestibular hypomineralization. In both cases, ICON was applied following the clinical protocol: etching with hydrochloric acid, dehydration with ethanol, and application of the infiltrant resin. The first patient showed partial esthetic improvement and reduced sensitivity. The second patient achieved a remarkable esthetic improvement in a single session, which had a positive impact on self-esteem. Conclusion: ICON resin infiltration proved to be an effective and safe method for managing vestibular hypomineralization, offering esthetic results in a single session. Accurate diagnosis and assessment of lesion depth are essential prior to treatment. Clinical follow-up and further studies are recommended to establish robust treatment protocols.
