Etch–Bleach–Seal Technique in Managing Enamel Hypomineralization: A Case Report With Narrative Literature Review

Background Molar incisor hypomineralization (MIH) opacities significantly affect pediatric patients′ esthetics and psychosocial well‐being. This case is unique as it demonstrates the clinical efficacy of a modified etch–bleach–seal protocol, utilizing a double application of sodium hypochlorite to address deep pigmentations where standard conservative approaches may be limited. Objective This study is aimed at evaluating the clinical efficacy and existing literature supporting the etch–bleach–seal technique, a minimally invasive approach developed by Wright for managing enamel hypomineralization–related opacities. Case Description A 10‐year‐old female presented with esthetic concerns regarding yellow‐brown discoloration on her upper central incisors. After clinical and radiographic evaluations, a diagnosis of MIH was established. The patient was treated using the etch–bleach–seal technique, including phosphoric acid etching, sodium hypochlorite bleaching, and ICON resin sealing. Outcomes Posttreatment, the patient showed significant improvement in enamel appearance. A follow‐up session at 3 months led to further enhancement of esthetic results. Conclusion The modified etch–bleach–seal protocol appears to be a promising conservative option for deep MIH opacities. However, as this represents a single clinical case, longitudinal studies are warranted to confirm its long‐term durability and impact on enamel integrity.
