This systematic review investigated the influence of light-cured luting agents and colour-associated factors. A search of in vitro studies that quantitatively investigated the influence of light-cured luting agents on the colour of ceramic laminate veneers was conducted. A meta-analysis was not possible due to heterogeneity. In all 3,630 studies were identified, 48 were selected for full-text analysis and 21 remaining papers met the inclusion criteria. Considering the shade aspects of luting agents, translucency and value showed the greatest visible colour differences for CLVs. It was found that the effect of luting agent shade on the colour of veneers was affected by ceramic thickness and opacity.
