Desensitization treatment in MIH-affected teeth: a systematic review

The present systematic review aims to summarize the current evidence regarding various treatment modalities and their results when dealing with hypersensitivity in teeth with Molar-Incisor Hypomineralization (MIH).

Systematic searches were conducted in PubMed and Scopus using the search terms "MIH AND Hypersensitivity AND treatment." Studies involving children aged 6–18 years diagnosed with MIH and exhibiting hypersensitivity were considered for inclusion. The outcomes examined included clinical, behavioral, and psychosocial treatment options for reducing hypersensitivity. A meta-analysis was performed for six of the included articles, and the I² value was calculated to determine heterogeneity.

A total of eight articles met the inclusion criteria for this review, with six eligible for the meta-analysis. Various treatment modalities, such as dental mousse, sealing, laser therapy, and crown therapy, demonstrated significant reductions in hypersensitivity individually (p < 0.05).

The treatment methods that offer the most effective reduction in hypersensitivity are sealing with resin composite or glass ionomer cement for mild cases of MIH, while crown therapy is more effective for severe cases of MIH. However, the small number of participants and short follow-up times limit the strength of these conclusions.
