Design and Manufacture of Dental Light Cure: Review on Biomaterial and the Effect of Wavelength on Composites Materials

Abstract

By replacing the use of various composites instead of amalgam, dental light cure is an integral part of restorative treatments. In the case of dental caries, it is very common to fill the space of the teeth with composite. Today, the clinical use of composite resin has increased. Due to the increasing use of optical composites, the importance of sufficient polymerization increases because their success depends on the degree of polymerization. Incomplete polymerization causes adverse biological effects, increasing water absorption, composite solubility and decreasing hardness. This is where the use of light cure devices in dental restorations is proposed. In the research conducted, light cure is designed with normal electronic elements and a very simple user interface by emitting blue light (cold visible) by high power and wavelength LEDs. Specific (400 to 520nm) performs the composite cure well in three different working modes.
