Preventive effect of glass-ionomer versus laser in Molar-Incisor-Hypomineralization affected molars

Objectives: Several treatment modalities can be applied for the management of teeth affected by molar-incisor hypomineralization (MIH), depending on the defects’ severity. This preliminary analysis is part of a larger study, aiming to verify the preventive effect of two treatment modalities against progression of the defect and dental caries in MIH affected molars.
Methods: 71 children (6-10 years) with at least one MIH affected molar (opacities without or presenting a post-eruptive breakdown restricted to enamel) were randomized into two groups: a) laser diode and b)glass ionomer sealant. Clinical examinations were performed at baseline and after 6 months, and a failure was considered when a progression of the defect and caries lesions were observed. Logistic regression and chi-square test were performed to verify the association between outcomes vs. variables related to the patient and the treatment received (α <0.05).
Results: After 6 months (drop-out 15%), there was no association between the treatment performed and the outcomes progression of the defect and caries. Additionally, no association was found between the failures and other independent variables (p> 0.05). However, there was an association between partial loss of sealants and progression of the defects (p <0.01).
Conclusions: INo difference was found between the types of treatments performed and the outcomes progression of the defect and caries in MIH affected molars after 6 months of follow-up; however, the partial loss of sealants were associated with progression of the defects.
