INTRODUCTION: Molar-incisor hypomineralization (MIH) corresponds to a qualitative defect of dental enamel of unknown etiology, but with a multifactorial characteristic, since both genetic, systemic and environmental factors may be involved. Clinically, demarcated and asymmetrical opacities with color ranging from white to brown are observed in first permanent molars, which may or may not affect the permanent incisors. Teeth affected by MIH can present aesthetic alterations, loss of tooth structure, caries lesions and dentin hypersensitivity and can have a negative impact on quality of life. OBJECTIVE: To report the case of a child diagnosed with mild MIH and to present aspects of the dental management of this condition. CASE REPORT: Male patient, melanoderm, 10 years old, with an aesthetic complaint in maxillary anterior teeth and without reports of complications or health problems during the pre-, peri- and postnatal periods, as well as in the first three years of life. In the intraoral clinical examination, demarcated opacities were observed on teeth 11 and 21, with a larger defect on tooth 21, which bothered the patient when smiling. In addition, demarcated opacity was also observed in the upper right first molar, tooth 16. The patient was diagnosed with mild MIH. For the proposed treatment, a sealant was applied with glass ionomer cement to the occlusal surface of tooth 16 and a minimally invasive approach was performed to mimic enamel changes in the maxillary permanent central incisors (microabrasion + application of resin infiltrant + application of flow resin bulkfill). FINAL CONSIDERATIONS: It is important that MIH is diagnosed as early as possible, ensuring that an appropriate treatment can be carried out and in an ideal period of time. This enables adequate preventive measures to be taken and a greater amount of tooth tissue to be preserved.
