摘要

Purpose

This study aimed to assess whether children with anterior molar–incisor hypomineralisation (MIH) experience bullying related to dental appearance and to evaluate whether a minimally invasive resin infiltration treatment of MIH-affected anterior teeth could reduce self-reported bullying and improve Oral Health–Related Quality of Life (OHRQoL).

Methods

Twenty-one children aged 8–14 years with MIH involving anterior teeth and self-reported bullying were enrolled in a single-arm clinical trial. Eligibility required affirmative responses to two items of the Child Perceptions Questionnaire (CPQ) specifically addressing bullying related to oral conditions, ensuring that all participants presented both anterior MIH and concomitant bullying experiences. Icon resin infiltrant (DMG, Germany) was applied to visible opacities. The CPQ was then administered at baseline and one month after treatment to assess changes in OHRQoL, whilst bullying experiences were reassessed at baseline and three months post-treatment. Data were analysed using Jamovi 2.3.28 with the McNemar test, Wilcoxon signed-rank test, Friedman test, and Durbin–Conover post hoc comparisons.

Results

All participants reported bullying at baseline, whereas none did so at the three-month follow-up (p < 0.001). Significant improvements were observed in the emotional and social domains of OHRQoL 1 month after treatment (p < 0.001), and these benefits were sustained over time.

Conclusion

Minimally invasive resin infiltration of anterior MIH lesions effectively eliminated self-reported bullying and significantly improved OHRQoL, highlighting the clinical and psychosocial benefits of early aesthetic intervention in affected children.
