Developmental hypomineralization of the enamel of the first permanent and the second deciduous molars - report of two cases

Introduction. Molar-incisor hypomineralization (MIH) is a developmental defect of dental enamel that affects one to all four first permanent molars (FPM) and frequently incisors. Enamel aberrations are observed as demarcated opacities different colors (from white brown) posteruptive breakdown. Clinically similar pathological signs can also be present in deciduous molars. Case outline. Histology an FPM second molar was performed after extraction from two unrelated patients with MIH due inflammatory complications. Tooth samples were analyzed using stereomicroscope (SM), light microscope (LM), scanning electron (SEM). thickness both affected teeth normal. An obvious distinction microstructure between the normally developed molar-incisor hypomineralized SM, LM, SEM. Conclusion. In patients, regular visits enable early diagnosis disease appropriate treatment patient soon possible, included preventive measures.
