Introdução: Atualmente presencia-se uma enorme demanda pela estética dentária, prevendo-se futuramente um aumento exponencial. A seleção da cor constitui assim um tema inerente a este fenómeno, tratando-se de um processo minucioso e influenciável não só pelas características pessoais de quem o realiza, como também por fatores como a luz, idade, formação, protocolo e biomateriais utilizados. Por forma a mimetizar a reprodução da cor é importante testar e compreender as novas metodologias disponíveis.
O presente estudo pretende avaliar a concordância na determinação de cor, quando é usado um filtro polarizador e na ausência deste.
Materiais e métodos: Foram realizadas 306 avaliações em 70 pacientes, utilizando a escala VITA Clássica e VITA 3D-Master, com e sem o uso do Smile Lite.
Resultados: Relativamente às escalas de cor utilizadas, a escala VITA Clássica obteve uma proporção de resultados concordantes significativamente superior. Verificaram-se diferenças significativas entre os terços quanto à concordância apenas com a escala VITA 3D-Master. O terço incisal do incisivo central superior foi o mais concordante, enquanto que no canino superior o terço mais concordante foi o médio. Relativamente à concordância entre género de avaliadores não se encontraram diferenças estatisticamente significativas. Verificou-se ainda uma maior concordância na faixa etária de pacientes superior a 50 anos para a escala VITA 3D-Master no incisivo central superior.
Conclusão: Segundo os resultados obtidos, a influência do Smile Lite pode ser verificada em determinadas situações, nomeadamente na divisão dentária por terços, constituindo assim um elemento válido e influente na seleção da cor dentária. Tendo em conta as conclusões apresentadas é relevante que no futuro se realizem mais estudos, devido à escassa literatura existente sobre o tema.
Introduction: Nowadays there is a huge demand for dental aesthetics, with an exponential increase expected in the future. Therefore, shade matching is an inherent thematic of this phenomenon, being a complex process and influenced not only by the personal characteristics of the person who performs it, but also by factors such as light, age, training, protocol and biomaterials used. In order to mimic shade reproduction, it is important to test and understand the new methodologies available. The present study intends to evaluate the agreement in color determination, when a polarizing filter is used and in the absence of it. Materials and methods: A total of 306 evaluations were performed in 70 patients using the VITA Classical and VITA 3D-Master guide, with and without the use of Smile Lite. Results: Regarding the color guides used, the VITA Classical guide obtained a significantly higher proportion of concordant results. There were significant differences between the thirds regarding the VITA 3D-Master guide. The incisal third of the upper central incisor was the most concordant. While in the upper canine the middle third was the most concordant. Regarding the agreement between gender of evaluators, no statistically significant differences were found. There was a greater concordance in the age group of patients over 50 years for the VITA 3D-Master guide in the upper central incisor. Conclusion: According to the results obtained, the influence of Smile Lite can be verified in certain situations, namely in the dental division by thirds. Thus, it is a valid and influential element in shade matching. Taking into account the conclusions presented, it is important that further studies are carried out in the future due to the scarce literature on the subject.
