Fluorescence properties and color space of modifying porcelains / 实用口腔医学杂志

ABSTRACT

Objective:To investigate the correlation between fluorescence emission and color difference (CIE△Eab). Methods:Color and spectral distribution in three kinds of modifying porcelains (Vita Interno, Shofu Vintage & Unibond, Noritake Super Porcelain EX-3) were measured on CIELAB color scale on Color-Eye 7000A spectrophotometer under four measuring modes. CIE△Eab were analyzed by two-way ANVOA and SNK-q test (?=0.05). Correlation analyses were also performed between CIE△Eab and the color parameters difference(?= 0.05). In addition, CIELAB color coordinate was established. Results:Fluorescence emission of Vita and Shofu, Vita and Noritake were significantly different(P
