Manejo clínico odontológico da hipomineralização molarincisivo – relato de caso

Abstract

INTRODUCTION: Molar-incisor hypomineralization (MIH) corresponds to an enamel development defect that affects between one and four first permanent molars, with or without changes in permanent incisors. Teeth affected by MIH may present aesthetic alterations, loss of tooth structure, caries lesions and dentin hypersensitivity and may represent a challenge for professionals, due to the higher percentage of failures in restorative procedures. Thus, early diagnosis of teeth affected by MIH will promote the institution of adequate treatment, minimizing the resulting damage. OBJECTIVE: To present the report of a clinical case of a child diagnosed with MIH and to present aspects of the dental treatment of this condition. CASE REPORT: Male pediatric patient, female, 11 years old, with chief complaint of “decayed tooth and stain on the front tooth”. There were no reports of intercurrences or health problems during the child's pregnancy, as well as in the first three years of life. On intraoral clinical examination, demarcated opacities ranging in color from white to brownish were observed on teeth 26, 36 and 41. The patient was diagnosed with moderate MIH. Dental treatment consisted of implementing measures to control caries risk factors, with motivation and guidance on oral hygiene, dietary guidelines, topical fluoride applications and periodic professional monitoring and follow-up. Indirect pulp capping and restoration with glass ionomer was performed on tooth 26, resin sealant on tooth 36 and aesthetic protocol on tooth 41 (microabrasion, infiltration and sealing with flow resin). FINAL CONSIDERATIONS: Studies with case reports can contribute to better knowledge about the diagnosis and dental management of MIH. Early diagnosis of individuals with MIH should be carried out for the adoption of preventive and interceptive measures in order to control, minimize and treat possible sequelae.
