Análise espectrofotométrica e visual do clareamento dental: relato de caso clínico / Spectrophotometric and visual analysis of dental bleaching: clinical case report

RESUMO

O trabalho apresenta descrição de um caso clínico de clareamento dental onde as alterações de cor foram avaliadas através de dois métodos: visual (utilizando escala Vita Clássica) e instrumental (utilizando espectrofotômetro Easyshade). Foi realizado clareamento dental de consultório com peróxido de hidrogênio a 35% Mix One Supreme (Villievie). A cor foi mensurada antes e após a realização do tratamento clareador com os dois métodos. O paciente relatou satisfação com a alteração de cor e esse resultado pôde ser comprovado tanto pela escala de cor quanto pelo espectrofotômetro. A técnica clareadora utilizada mostrou-se eficiente, porém, para resolver completamente o problema estético do paciente foi realizado também fechamento de diastema com resinas compostas fotopolimerizáveis.

ABSTRACT

Tooth color is considered a complexity phenomenon, influenced by coefficients such as environment illumination conditions, translucence, opacity, light spread, brightness, and structures and morphophysiological processes of sight. The aim of this study was to describe a clinical case of dental bleaching, in which the modifications of color were evaluated by two methods: visual (using Vita Classic scale) and instrumental (using Easyshade spectrophometer). A clinical dental bleaching was performed with hydrogen peroxide at 35% Mix One Supreme (Villievie). The color was measured before and after the bleaching with both methods. The patient reported satisfaction with the color alteration, and that result can be testified both by color scale and spectrophometer. The bleaching technique was very effective, however, in order to solve the esthetic problem completely, diastema was also closed with compound photopolymerizable resin.
