Effects Of Dentifrices On Discolouration Of Cad Cam Manufactured Temporary Restorative Materials

Aim: To assess the effects of dentifrices on discolouration of CAD/CAM manufactured temporary restorative materials. Introduction: Color match is one of the most important characteristics of aesthetic restorative materials. Maintenance of color throughout the functional lifetime of restorations is important for the durability of treatment. This characteristic is not constant among dental materials. Restorative materials must maintain long-term color stability in order to avoid replacement of restorations. Color differences (ΔE) more than 3.3 units reflect clinically significant visual discoloration. The degree of discoloration of resins can be influenced by a number of factors such as incomplete polymerization, water sorption, chemical reactivity, diet, oral hygiene or surface roughness of the restoration. Discoloration can be due to extrinsic or intrinsic cause. The null hypothesis was that colour stability of tested materials were not affected by the dentifrices or toothbrushing simulation.
