Abstract

Objective: Identification of selected characteristics before and after 6-month treatment with resin infiltration for clinical molar–incisor hypomineralization lesions in 8-11-year-old children in Hanoi, 2025. Subject and methods: A cross-sectional description of 59 children aged 8-11 with 123 MIH-affected teeth, including treatment of 48 anterior teeth with mild MIH using ICON resin infiltration (DMG, Germany), followed up for 6 months. Results: White or cream opacities were the most frequent lesions (56,10%), higher in incisors (77,42%) than molars (34,43%). Most were grade 1 (<1/3 crown surface with 89,43%). Discoloration occurred in 38,21% with caries before treatment at 6,25%. Anterior discoloration was 14,58% before treatment; 0,00% immediately after, and 39,58% at 6 months. All differences were statistically significant (p<0,001). Conclusions: In children aged 8-11 years, MIH lesions were predominantly white or cream opacities with limited extension (<1/3 of the crown surface) and low surrounding discoloration. Posterior teeth were more severely affected than anterior teeth. Resin infiltration was highly effective for mild lesions, although relapse of discoloration was observed at 6 months.
