Abstract
Objective: To evaluate a two-year clinical performance of resin infiltration in anterior teeth affected by Molar Incisor Hypomineralisation (MIH), focusing on esthetic outcomes, hypersensitivity control, and patient-reported satisfaction. Materials and Methods: This retrospective observational study included 106 MIH-affected permanent incisors from children aged 7–10 years, treated at a universitybased pediatric dental clinic. The primary outcome was esthetic improvement (colour match, FDI criteria). Secondary outcomes included patient-reported hypersensitivity (VAS), additional esthetic and
biological properties from the FDI index, and patient and guardian satisfaction. Esthetic and biological properties, hypersensitivity, and satisfaction were recorded at 1, 12, and 24 months following resin infiltration of demarcated opacities. Data were analysed using descriptive and comparative statistics. Results: A two-year clinical success rate of resin infiltration was 96.2% based on colour match. Hypersensitivity scores (VAS 0–10) decreased from 8 at baseline to 0 at 24 months. Success rates for esthetic and biological properties, as assessed with the FDI index, all exceeded 90%. Patient and guardian satisfaction was high at 1 and 12 months but declined at 24 months, particularly in cases with yellow-brown demarcated opacities. Conclusion: Resin infiltration showed high effectiveness for improving esthetic integration and colour match in anterior teeth affected by MIH, with high initial satisfaction reported by patients and guardians.
