Light cure resin-based composites can be polymerized using dental curing light. Developed in the early 1960s, the dental curing light has gone through major developments, one of them being the use of light-emitting diodes (LED). These Dental LED Curing Lights cure the dental material by emitting a blue light through the use of one or more LEDs. First suggested for use in 1993, these curing lights are the best choice to treat restoration materials like composites. This light uses a gallium nitride-based semiconductor for blue light emission.
The most recent progression in innovation is LED curing light and they are generally utilized in the dentistry. LED curing light have their various wavelengths and infiltration time and some have intensity meter as well. They are progressively lightweight and consume less power. The heat generated from LED curing light is substantially less which means it doesn't require a fan to cool it. They are accompanied with rechargeable batteries, making it a lot simpler and comfortable to use.
Comparison to Halogen Lights
If we compare LED curing lights to halogen lights, we find that LED lights are much more lightweight, portable and have more effect. Also, the material is cured much faster by using LED lights than while using Halogen lights.
By use of dental endodontic treatment the life of these lights can be substantially increased and the efficiency can be maintained. These lights have emerged as the most preferred choice of dentists to polymerize composites.
