Manejo clínico da hipomineralização molar incisivo: revisão de literatura

Abstract

Molar Incisor Hypomineralization (MIH) is an enamel defect characterized by decreased mineralization of the dental element, which affects between one to four permanent first molars; permanent incisors can also be affected. It has a systemic and multifactorial origin, related to disorders that occur between the prenatal period and the first three years of life. To describe the treatment possibilities to the Molar incisor hypomineralization condition, a bibliographic review of the national and international scientific literature was carried after a search for papers that presents results of restoration treatments of teeth affected by alteration. Papers that evaluated prevention treatments were selected and gray literature was also included. According to the literature, this condition can cause post-eruptive fractures, caries lesions associated with affected enamel, tooth hypersensitivity, among other aggravating factors that make the treatment of this pathology very challenging. The application of sealants, the use of desensitizers, restorations, steel crowns and even extractions are related to the treatment of the affected first molars, while the treatment of the incisors involves a microabrasion, infiltrates the resin, whitening and facets. It was concluded that it is not yet possible to define a single material or technique as the ideal treatment for this condition, however, it is known that a correct diagnosis of a certain disease, as well as its severity, will be a unique guide for choosing the treatment. . It should be noted that early diagnosis becomes a great ally for more conservative treatments, reducing painful symptoms and more favorable prognosis, as well as the periodic monitoring of this change allows for higher success rates in long-term treatments.
