Comparison of different treatment modalities in hypomineralized primary teeth

Abstract

Aim: The purpose of the present research was to evaluate various modalities for treating hypomineralized primary teeth. Methodology: Survival data retrospectively collected from 52 children with MIH, monitored. We evaluated one hundred and twenty unknown, high-quality photographs from occlusal and smooth surfaces, respectively, for the detection of cavitated carious lesions and caries-associated restorations (DMF index) and MIH. Descriptive and explorative analyses were performed, including Kaplan-Meier estimators. Results: The mean patient observation time was 42.9 months (SD = 35.1). The cumulative survival probabilities after 36 months—7.0% (GIC, N = 28), 29.9% (non-invasive composite restoration, N = 126), 76.2% (conventional composite restoration, N = 27) and 100.0% (ceramic restoration, N = 23)—differed significantly in the regression analysis. Conclusion: Conventional restorations were associated with moderate-to-high survival rates in MIH teeth.
