CONSERVATIVE ESTHETIC TREATMENT OF INCISORS AFFECTED BY MIH AND DENTAL FLUOROSIS THROUGH RESIN INFILTRATION: A CLINICAL CASE REPORT

Abstract

This study aimed to evaluate the clinical and esthetic effectiveness of the resin infiltration technique in the treatment of enamel stains associated with molar-incisor hypomineralization (MIH) and dental fluorosis. This is a clinical case report with a descriptive and qualitative approach, conducted on an 11-year-old patient presenting whitish opacities on the permanent maxillary incisors. The clinical protocol included prophylaxis, infiltrative anesthesia, absolute isolation, superficial microabrasion, conditioning with 15% hydrochloric acid (Icon Etch), application of a drying agent (Icon Dry), and infiltration of low-viscosity resin (ICON®), followed by light curing. Three conditioning cycles were performed to optimize material penetration. The evaluation of results was carried out through standardized photographic records and the application of a Likert-type satisfaction scale before and after the procedure. A significant esthetic improvement was observed, with reduction in lesion opacity and greater enamel uniformity, in addition to a marked increase in patient satisfaction, which changed from “very dissatisfied” to “very satisfied.” It is concluded that resin infiltration constitutes an effective, safe, and minimally invasive therapeutic alternative for the esthetic treatment of enamel alterations.
