Reabilitação estética de dentes com mancha por tetraciclina por meio de facetas diretas em resina composta

Abstract

Tetracycline is a broad-spectrum antibiotic used in the treatment of several bacterial infections. However, its administration during odontogenesis may result in the incorporation of the drug into mineralized tissues due to its ability to bind to calcium ions, causing intrinsic tooth discoloration. The severity of pigmentation is related to the administered dose, duration of treatment, and stage of dental mineralization, and may present color variations ranging from yellow, gray, and brown shades. These alterations may compromise smile aesthetics and negatively impact the patient’s quality of life, potentially indicating the need for restorative approaches. In this context, direct composite resin veneers represent a conservative and effective alternative for the aesthetic rehabilitation of tetracycline-discolored teeth. The present study aims to report a clinical case of a 23-year-old female patient with tetracycline-induced tooth discoloration, submitted to the association of in-office dental bleaching and aesthetic rehabilitation through direct composite resin veneers, as well as to perform a literature review on therapeutic approaches for tetracycline-pigmented teeth.
