AMELOGENESIS IMPERFECTA: REPORT OF A CONSERVATIVE AESTHETIC REHABILITATION

Abstract

Objective: The aim of this study was to report a case of an aesthetic rehabilitation in a patient with amelogenesis imperfecta, who was treated with the use of the enamel microabrasion technique associated with composite resin. Case Report: An 18-year-old female patient was admitted to the Dental Clinic of the Federal University of Paraíba in need of aesthetic treatment in her maxillary anterior teeth. After anamnesis and detailed clinical examination, the patient was diagnosed with amelogenesis imperfecta. The enamel microabrasion technique in association with composite resin was proposed to restore the dental areas showing loss of substance. The stains were minimized by the enamel microabrasion technique using a mixture of 37% phosphoric acid and pumice stone, followed by fluoride topical application. In order to achieve a better aesthetic result, increments of composite resin were used in the areas that showed enamel slope. The enamel was etched with 37% phosphoric acid for 30 seconds, rinsed for 15 seconds, and dried with tissue paper. Then conventional adhesive was applied and light-cured for 20 seconds, followed by incremental application of composite resin (nanofilled composite resin, EA3). Conclusion: Enamel microabrasion was an effective technique to minimize stains. When associated with the use of composite resin, aesthetic recovery of the affected teeth was observed.
