Abstract

Sixty non carious maxillary premolar teeth were used in this in vitro study. The teeth samples were randomly divided into six groups of ten each according to the luting cements used for luting the porcelain laminate veneers. Sixty porcelain laminate veneers were fabricated from lithium disilicate glass ceramic ingots IPS Empress Esthetic. The corresponding veneer’s surfaces were conditioned with six different luting cement following the manufacturer’s instructions. The color determination of each sample was accomplished by the color spectrophotometer VITA Easyshade. Following the color determination of each sample, the porcelain laminate veneers samples were placed in sodium chloride 0.9% in aqueous solution between -10°C and +50°C. Following the exposition in sodium chloride 0.9%, follow up color measurements were performed following a similar procedure at the identical areas for each sample. The luting cements used in the study had various ranges of color change after the accelerated ageing process. The mean color changes observed in the group I (dual cure) was highest - 2,497. The group II (light cure) had mean value at 1,116. The group III and group IV (self-etch) had mean values at 2,363 and 2,284. The group V and group VI (self-adhesive) presented the lowest color change values at 0,620 and 0,613 respectively.

Key words:

porcelain laminate veneers, color change, luting cements
