MICROABRASÃO DO ESMALTE

Abstract

Enamel defects are described as changes in its structure characterized by local decrease or loss of its translucency from fluorosis, hypocalcifications, hypoplasias and inactive carious lesions with superficial and medium depth. The microabrasion of enamel selectively promotes the removal of its surface layer that presents color or structure modification through a mixture of abrasive and erosive agents mechanically. The association of these agents exposes a sub-layer of enamel with normal characteristics. This procedure can be used alone or associated with one or more aesthetic treatments, such as tooth whitening and composite resin restorations. Objective: to approach the microabrasion technique applied in dental enamel with changes in color and structure. Methodology: a non-systematic review of the scientific literature, published from 2009 to 2019, was carried out in the Virtual Health Library and in the academic Google. The inclusion criteria were articles in Portuguese and English, published in the last 10 years, that addressed the proposed theme. Conclusion: Dental microabrasion is a good alternative for aesthetic treatment for changes in the superficial structure of dental enamel, fluorosis and hypoplasia, because it wears little dental structure, restores aesthetics, does not cause damage to the pulp or periodontal tissues, requires little treatment time, does not require cavitary preparation, nor restorative material and is low cost. Aesthetic dissatisfaction is a concern of patients of all ages and the diagnosis of dental fluorosis should be the result of careful anamnesis and it should be taken into account that the etiology may be of various origins.
