Avaliação da eficácia clareadora utilizando-se de barreira gengival fotopolimerizável para proteção de manchas de fluorose um relato de caso clínico

Abstract

Introduction: Dental fluorosis occurs due to excessive exposure to fluoride during tooth formation, resulting in opaque or pigmented stains on the enamel. This can affect both aesthetics and dental function. Objective: This clinical case report aims to present a whitening technique with high-concentration hydrogen peroxide, combined with the application of a light-curing gingival barrier, to treat teeth with dental fluorosis. Case Description: A 27-year old patient sought treatment because of white spots and yellowish coloration on her teeth. The diagnosis was grade 2 fluorosis. Treatment included two sessions: the first with application of 35% hydrogen peroxide, and the second with protection of the white spots using a light curing gingival barrier and whitening with hydrogen peroxide. Conclusion: After treatment, there was a significant improvement in tooth shade and a reduction in fluorosis stains. The patient reported no pain and was satisfied with the aesthetic result. The approach was effective and minimally invasive, preserving tooth structure and offering satisfactory aesthetic results.
