Resumo: A restauração de um dente mantendo sua naturalidade sob quaisquer circunstâncias é uma tarefa difícil, devido às complexas características ópticas que influenciam neste processo. Fenômenos ópticos como a cor do dente, sua translucidez, opacidade, opalescência, fluorescência, fonte luminosa ambiente e seus relativos efeitos de metamerismo, têm um papel importantíssimo na maneira como percebemos um dente e, consequentemente, o processo de mimetização realizado durante o tratamento restaurador. O sucesso nos resultados estéticos depende da integração de alguns fatores que se tornam críticos para tal: conhecimento de princípios básicos sobre a percepção das cores, percepção inerente a cada indivíduo, fonte de luz utilizada durante a avaliação da cor, características estruturais de superfície dos dentes e dos materiais restauradores utilizados, registro destas informações e a comunicação com o laboratório quando forem realizadas restaurações indiretas. Neste contexto, tendo como objetivo final o desenvolvimento de uma percepção mais apurada das características estéticas da dentição natural, este artigo buscou revisar a literatura com o intuito de auxiliar o clínico a adquirir o entendimento de princípios relacionados à cor, luz e as propriedades ópticas que são inerentes aos dentes,cerâmicas e resinas compostas.

Palavras-chave: cor; estética; fluorescência; óptica e fotônica.

 

Abstract: The restoration of a tooth keeping its naturalness under any circumstances is a difficult task due to the complex optical characteristics that influence this process. Optical phenomena such as tooth color, their translucency, opacity, opalescence, fluorescence and even the type of light source environment and its effect on metamerism, have a very important role in how we perceive a tooth and, consequently, the smile of a particular individual, thus affecting the process of mimicry performed throughout the restorative treatment. The success of the aesthetic results requires the integration of some factors that become critical for this: the knowledge of basic principles of color perception, the perception inherent to each individual, the light source used for the evaluation of color, the structural and surface characteristics of teeth and restorative materials used and, finally, the record of this information and its communication to the lab when indirect procedures are performed. In this context, having as ultimate goal the development of a more accurate perception of the aesthetic characteristics of natural dentition, this paper aims to review the literature in order to assist the clinician to acquire the understanding of principles related to color, light and optical properties inherent to the teeth, ceramics and composite resins.

Key words: color; esthetics; fluorescence; optics and photonics.
