Dental curing lights are used to harden and set dental materials such as composites and adhesives and promote the curing of resin cement. They work by emitting intense light to activate the photoinitiator in the dental material, which starts polymerization. The light is emitted in the form of either ultraviolet (UV) or visible light.
Light curing of dental materials is more comfortable for patients than traditional methods such as air or moisture-curing. There is no unpleasant smell, and the procedure is quick and straightforward.
Curing light technology is an integral part of the dental restoration process, as it hardens the resin material that has been applied to the tooth. The light is emitted by a handpiece, which then cures or hardens the resin material. The light can come in different wavelengths, depending on the resin being used.
Modern dental curing lights are cordless and battery-operated. This allows for greater mobility during use and reduces any potential fire hazard caused by having a power cord within proximity to dental materials. Curing lights are available in various sizes and are made with varying power output capacities for differing needs.
Curing lights are used in various dental procedures, such as:
- Dental composite crowns and bridges
- Dental fillings and inlays
- Dental veneers and laminates
- Direct composite restorations of natural teeth
Gum disease laser therapy is a procedure used by dentists to treat gum disease. Dental teams use this procedure to remove the bacteria and other materials that can cause gum disease and help reduce gums’ pain and swelling.
The procedure involves using microscopic laser beams to remove the bacteria. Additionally, the laser removes the bacteria without causing any damage to the surrounding tissue or requiring cutting or stitches after the procedure. The use of lasers is more effective in removing gum disease than traditional methods of treatment.
After the laser therapy, it is recommended that patients follow up with dental professionals to prevent any future problems with gum disease. Dental professionals can also help you prevent future problems from developing and remind you of the importance of brushing and flossing your teeth daily.
Picking the right dental curing lights is an important decision, as many factors are considered. Some lights are designed for more than one type of material, but some curing lights are explicitly made for one type of material. Procedures, such as laser teeth whitening, rely on a specific curing light.
It depends on the type of material that is used. For example, if a composite resin is used, then an LED light is the best option.
Dental curing lights emit large amounts of ultraviolet radiation, and dental professionals use them only when wearing protective eyewear. If the light is used when it is not necessary, when an appropriate shield is not used, when it is too close to the skin, or when the light is not working correctly, it can lead to skin burns or eye damage. To avoid these risks, dental professionals take the following precautions:
- Turn off the light before leaving the room
- Use a timer on the light to ensure that it is turned off for an appropriate amount of time
- Keep the light as far away from any living tissue as possible
- Use protective eyewear at all times while using a dental curing light
- Only use the light in an area that has been tested for reaction
- Make sure the lamp is not damaged in any way before using it
- Make sure that no liquids have been spilled on or around the lamp before using it
- Always supervise children and those with sensitive skin
- Avoid looking directly at the light after it has been turned off
- Use a UV filter on the light that will block 99% of UV rays
