Light Cure Devices

Abstract

With the invention of light‑cured resin materials used in bonding and restorations, the use of light cure units has become an integral part of dentistry. There is a vast change in the curing devices over the last 30 years. At present, the following types of light‑curing devices are available – Quartz‑tungsten‑halogen, light‑emitting diode, plasma arc curing, and Argon laser. This review is primarily focused on discussing the types and limitation of each type of light cure units and also maintenance of light cure units to optimize their use.
