Microabrasion and composite resin for re-establishing smile esthetics: a case report

Dental hypomineralization such as dental fluorosis has increased in recent times leading to unaesthetic appearance of teeth. There are different treatment possibilities to improve the aesthetic appearance of hypomineralized enamel described in dental literature. The enamel microabrasion has been a feasible alternative, since it is a fast, safe, conservative, and easy to perform, which promotes good esthetic results. Moreover, this technique is a conservative method that improves the appearance of the teeth by restoring bright and superficial smoothness, without causing significant structural loss. The association of different techniques, such as direct composite resin, can provide good esthetic outcomes, but the etiology, intensity, and depth of stain should be considered to minimize dental structure loss. Objective: To describe an easy technique for managing dental fluorosis using enamel microabrasion in association with direct composite resin. Case report: A mixture of hydrochloric acid and silicon carbide was applied according the manufacturer’s instructions. Subsequently, a direct composite resin was applied over the areas where the opacities were more evident. This conservative approach may be considered an interesting alternative treatment to remove fluorosis staining and to improve aesthetic appearance. Conclusion: enamel microabrasion combined with direct composite resin is a conservative and safe alternative method to treat enamel opacities from dental fluorosis. Therefore, this management provides satisfactory aesthetic results for the patient’s smile.
