“…In the latter case, the eye may have been distracted by gloss, translucency, milky opacities, surface irregularities, and shape. 39,42 Furthermore, due to its functional principle, which measures the reflection of a flash of light transmitted to the heart of the tooth, the Vita Easyshade spectrophotometer is more sensitive to dentine chroma and L tones, unlike the conventional visual assessment.…”

“…3 TP is a reliable method for evaluating translucency, and several studies have investigated the TP values of resin composites and dental porcelain. [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] Light transmittance (%T) is defined as the mean percentage of the light spectrum passed through the specimen relative to direct transmittance. 20 Several researchers have measured the light transmission of dental materials and used it as an index of translucency.…”

Composite translucency varies by manufacturer. This information should be considered when selecting materials and clinical techniques to improve clinical performance. SUMMARYThe purpose of this study was 1) to compare the translucency of seven different types of composite materials and three different shade categories (dentin, enamel, and translucent) by determining the translucency parameter (TP) and light transmittance (%T) and 2) to evaluate the correlation between the results of the two evaluation methods. ) from different manufacturers were screened in this study. Ten disk-shaped specimens (10 mm in diameter and 1 mm in thickness) were prepared for each material. For the TP measurements, the colors of each specimen were recorded according to the CIELAB color scale against white and black backgrounds with a colorimeter and used to calculate the TP value. For the %T measurements, the mean direct transmittance through the specimen in the range between 380 and 780 nm was recorded using a spectrometer and computer software. Two-way analysis of variance (ANOVA) tests were performed to compare the TP and %T for the composite materials and shade categories. One-way ANOVA and Tukey tests were used for the seven composite materials per shade category and the three shade categories per composite material. The correlation between the two evaluation methods was determined using the Pearson correlation coefficient. All statistical procedures were performed within a 95% confidence level. TP differed significantly by composite material within each shade category (p,0.05) and by shade category within each composite material (p,0.05). %T differed significantly by composite material within each shade category (p,0.05) and by shade categories within each composite material (p,0.05), except for BF and ES. For the two evaluation methods, TP and %T, were positively correlated (r=0.626, p,0.05). These methods showed strong correlation for each composite

“…[2][3][4] Recently, some authors evaluated the influence of tooth bleaching on the translucency of enamel and reported the decrease of this attribute after bleaching. 5,6 In despite of color and translucency are considered the main factors in the appearance of teeth, 7 other factors are also important, such as the opalescence of the enamel. The opalescence is an optical property produced by scattering of the shortest wavelengths of the visible spectrum, making opalescent objects more blue when observed under reflected light and more orange under transmitted light.…”
