They are the tooth coloured materials composed of resin base and other fillings. These types of fillings come in a variety of shades to match the colour of the tooth. The fillings are hardened by shinning to the surface for 30-40 seconds with an intense blue light (400-450 nm) from special light source such as LED (light-emitting diode). The main advantage of the composite is aesthetics especially in anterior or buccal posterior teeth as well as non stress occlusal surface on posterior teeth. At the same time, they are technique-sensitive and need more steps to follow precisely by the dentist. Advantages and limitations are presented in the article in order to assist the patients in making a decision consultation with the dentist. Keywords: dental restorative filling, light-cured composite resin, resin base, light source, LED (light-emitting diode) ใจนุช จงรักษ์
