CLINICAL MANAGEMENT OF MOLAR-INCISOR HYPOMINERALIZATION: TREATMENT OUTCOMES AND CHILDREN’S QUALITY OF LIFE IN A CRITICAL NARRATIVE REVIEW

Abstract

Objective: To critically analyze contemporary evidence on the management of molar-incisor hypomineralization (MIH) in children and adolescents, distinguishing hypersensitivity relief, restoration success, tooth preservation, and oral health-related quality of life (OHRQoL). Methods: A critical narrative review with structured thematic searching and selection of clinically relevant guidelines, reviews, and original studies published primarily between 2021 and October 2026, identified through PubMed records and supporting academic search tools. Evidence was synthesized qualitatively, without claiming exhaustive retrieval or conducting a meta-analysis. Results and discussion: Preventive and desensitizing interventions show promising outcomes, although available studies are heterogeneous and often have short follow-up periods. A trial involving 72 restorations found no statistically significant difference in 12-month survival between glass ionomer cement and composite resin (91.7% versus 88.9%) and highlighted fractures in residual enamel. A six-year cohort documented declining restoration survival, particularly in severe cases. Reviews suggest improvements in OHRQoL following treatment but indicate low certainty of evidence and potential overlap among studies. Final considerations: Treatment decisions should be individualized and monitored longitudinally. Restoration retention does not necessarily indicate whole-tooth preservation or psychosocial improvement. Child-reported outcomes should complement clinical endpoints.
