Home › Guides › Top 5 Dental Light Curing Units for Composite Restorations
How to select a curing light that fits your practice Durable restoration relies on the right kind of curing light to be effective and long-lasting. But deciding what type of curing light to choose can be demanding, especially when you can only rely on the manufacturer’s claims. If you have a restorative practice, it’s an essential product because an effective light will achieve success, while an inefficient one will make efforts tedious and less consistent. Below, we’ll give you a basic outline of the basics and what experts, such as the Dental Advisor, say about choosing curing lights.
Types of Curing Lights
LED Lights – L.E.D., or Light Emitting Diode, restricts the current flow of light into one direct through its connection to a circuit. These curing lights are lightweight, small, have a long battery light, and by today’s standards, give off the most consistent curing by their design. L.E.D. can refer to either blue light or multi-wave light of both blue and violet. The blue light activates the photoinitiator, while the multi-wave activates both the photoinitiator and alternative initiator. Some may lack tip selections, lack timers, and may have a harder time curing certain composites. Most new-style L.E.D. curing lights have a better time with beam divergence, and any tips that fan out the light in a cone shape can divert the curing process and divert the energy needed to cure the composite.Halogen – While considered to be an outdated product by industry standards, halogen lights have a reliable long track record for creating consistent cures. Halogen curing lights have a wider selection of curing materials they can work with due to their wide bandwidth. However, its design causes the need for cooling fans and a cord but does benefit from lower prices.Plasma Arc – A plasma arc curing light is an aluminum oxide vessel containing high-energy xenon gas under 150 psi. These curing lights produce focused beams and are typically designed within large base units and small tips for the desired effect. However, it cannot cure all materials and can be expensive.Argon Laser – Argon lights generate light by applying energy to the argon gas atoms. The electrons are raised higher in numbers to an unstable level and then release light through the argon gas. As some of the most expensive forms of curing lights, these create fast curing times and require a large unit to encompass the laser . However, it may not cure all materials and require small tips and cords to function. Our Recommendations for Curing Lights Curing lights should be able to have access to both adult and pediatric patients, getting into the right angles without interfering with the composite. It should have enough intensity to ensure a good cure, an intensity between 750 to 2000 milliwatts per square centimeter. Any curing light that generates watts higher than 2,000 can generate excessive heat and cause a waste of energy, which will not cure the composite any faster.
While higher wattages can appear attractive, they don’t always cure the composite faster. As a dentist, you should follow the suggested curing times from the composite manufacturer, not the light manufacturer.
Find a curing light that gives off a homogeneous, uniform light beam between 3 to 10 mm, and curing lights that produce hot spots should be avoided at all costs due to their lack of consistency with the composite. Keep things simple, and be aware of the differences between certain lighting options in their power, modes, and light source.
