Infiltrante resinoso para tratamento das opacidades em esmalte: uma revisão de literatura

Abstract

INTRODUCTION: Dental caries is one of the most prevalent oral pathologies and manifests early as White Spot Lesions (WSLs). These opacities are a major esthetic problem, associated both with incipient carious lesions and developmental defects, such asdental fluorosis. These lesions compromise smile harmony and are difficult to resolve through remineralization alone. Resin Infiltration (RI) has emerged as an excellent minimally invasive alternative. Its effectiveness is supported by the infiltration of low-viscosity resin into porous enamel and, due to its refractive index being similar to that of healthy enamel, it is able to camouflage the white spot lesion. As it is an innovative material, modern science debates the durability of the technique. OBJECTIVES: To analyze the available scientific evidence regarding the effectiveness of resin infiltrant in the treatment of enamel opacities, focusing on the mechanism of action, esthetic success (objective and subjective evaluation), and the perspectives for the evolution of the technique. METHODOLOGY: This study is a literature review. The search will be conducted in electronic databases such as PubMed, Scielo, and Google Scholar. Articles published in English between 2009 and 2024 addressing clinical studies, laboratory trials, and reviews will be selected. After selection and reading, descriptive information from the articles will be collected and organized for analysis and discussion. EXPECTED RESULTS: It is expected that the results will confirm the effectiveness and durability of resin infiltrant as a superior and minimally invasive alternative for the esthetic treatment of enamel opacities. It is also expected that the consolidation of this scientific evidence will provide a safe and efficient treatment protocol capable of restoring patients’ self-esteem and comfort.
