A curing light is a light which is designed to rapidly cure a resin
A curing light is a light which is designed to rapidly cure a resin. Curing lights are used primarily in the dental industry, where they are used in fillings, sealants, and adhesives for various dental procedures. Other versions of the curing light can be seen in use in manufacturing, where rapid and even curing can be an important part of the manufacturing process. A number of companies produce curing lights which have been custom designed for particular applications, ranging from electronics to dentistry.
In the dental handpieces, a curing light can use ultraviolet or visible light, depending on what it is designed for. Both dentist and patient need to wear eye protection to limit damage to the retina for even the 20 seconds to a minute that the light is in use during rapid curing, and the light needs to be well maintained so that it will work properly and effectively. It's also important to use the right curing light for the right resin product; many lights are designed to handle a range of resins safety.
Using a curing light accomplishes two things. In the first place, it makes sure that the resin cures properly and adheres evenly. When applying fillings, this is critical to keep the filling in place in the mouth. For sealants, the curing light limits the risk of cracks and other problems with the sealant. With adhesives for implants and braces, the rapid, even cure is also designed to limit problems in the future.
