Percepção de leigos e cirurgiões-dentistas em fatores que influenciam na restauração com laminados cerâmicos: efeito da espessura da lâmina e cor do cimento

Abstract

Introduction: The use of ceramic veneers is becoming increasingly common, which implies the importance of knowing the factors that influence the final restoration. Studies have shown that factors such as ceramic blade thickness and cement color may influence the final color of the restoration. In addition, because it is generally an esthetic treatment in anterior teeth, laminates veneers are easily observed by clinicians and lay people. Purpose: The aim of this study is to evaluate if the color differences in ceramic veneers are seen in the same way by dentists and layman, and also to evaluate if the thickness of the ceramic and the color of the cement influence the final color of the restoration. Material and methods: Nine samples simulating a restoration with ceramic laminates were prepared. Three different thicknesses of ceramic (0.5 mm, 1.0 mm and 1.5 mm) and three different colors of cement (T, A1 and OW) were evaluated. After preparation, the samples were divided into subgroups and presented to laypeople and professionals in the area, so that they answered a questionnaire that was used for the research. Results: The highest perception of color change was in samples with 0.5 mm of thickness of the ceramic, and in samples cemented with OW cement. In these cases, laypeople and professionals in the area showed a significant difference in perception. Conclusion:The results confirmed that the thickness of the laminate and the color of the cement influenced the final color of the restoration and showed that both dentists and lay people can identify these differences in the color of the restoration.
