Different approaches for aesthetic management of molar-incisor hypo-mineralization: two case reports

Abstract

Background: Molar-incisor hypo-mineralization (MIH) is a developmental enamel defect that affect one or more permanent first molars, with or without incisor teeth involvement. When incisors are affected, that might lead to aesthetic concerns and consequently, negative impact on the child's quality of life. Hence, this study presented and discussed the conservative treatment modalities for maxillary incisors with discolored enamel defects. Case Presentation: Two 12-year-old female patients was referred from pediatric clinics to treat anterior teeth discolorations after management of affected first molars. In the first case, the defect was more heterogenous with yellow-brownish discoloration. To remove yellow-brownish discoloration, in-office bleaching with 37% hydrogen peroxide was performed, followed by home bleaching with 10% carbamide peroxide for one week. Then, resin infiltration (RI) was performed to seal the porous enamel and to mask the white enamel defects. In the second case, the white opacities were more homogenous, therefore, only RI treatment was applied. Conclusion: Aesthetic management of MIH patients should follow more conservative approaches like dental bleach systems and resin infiltration.
