Fluoride-releasing restorative materials are often combined with topical fluoride application products in order to enhance fluoride effects. The purpose of this study was to determine the colour stability of 3 aesthetic fluoride-releasing restorative materials after application of 2 topical fluoride products. 15 disc shaped specimens were prepared for each restorative material and were divided into 3 groups. Topical fluorides were applied onto the specimens according to the manufacturer’s instructions. The procedure of fluoride application was repeated twice. Colour properties of all specimens were evaluated at baseline and 48 hours after topical fluoride application. Colour analysis was performed using the spectrophotometer and CIE L*a*b* method. 3 consecutive readings were recorded for each specimen and L*, a*, b* parameters and a mean number of readings were calculated.
