What Are the Different Types of Dental Curing Lights?

Jul 07,2023

Today, a dental curing light is a necessity in clinics. Like other dental equipment, the dental curing light also keeps developing in the dental curing lights market over the years.

Then, in this post, the author will give an introduction to the use of dental curing lights and list the current major types of dental curing lights.

What Does a Curing Light Do?

A curing light is a dental tool used to polymerize and cure dental materials, such as composite resins, in various dental procedures. Its primary function is to activate photoinitiators within the dental materials, initiating a chemical reaction that leads to the hardening and solidification of the materials.

What is Halogen Curing Light?

The dental halogen curing lights are the original version of curing lights used for the polymerization and curing of dental materials like composite resins. In dentistry, the dental halogen curing lights can quickly and effectively harden and set the dental materials by emitting blue light between 400-500 nm. During the working process, the dental halogen curing lights can become very hot, so they include a fan to cool the bulb.

What is Dental Led Curing Light?

The dental led curing light is a modern and advanced hand-held curing light. It is mainly used for curing dental materials, particularly composite resins.

Compared with the halogen curing light, it tends to shorten the curing time on various dental procedures, such as tooth restorations, fillings, and bonding.

During the working process, the light cure emits a precise wavelength of light, usually in the blue spectrum. This light activates the photoinitiators present in the composite resin, leading to a chemical reaction that kickstarts the curing process.

What is Dental Plasma Arcs Curing Light?

The dental plasma arcs curing light is a newly launched curing light used for curing resin-based composites and bleaching teeth. As the development of the dental curing light, this type of curing light also gets developed in the working modes. Several working modes are available in this type of light curing units dentistry such as ramp, step, and bleaching mode. As for the curing time, this type of curing light can cure the materials in less than 5 seconds.

Which is Better Halogen or LED Curing Light?

According to the current research, the led curing light is better than the halogen curing light.
Curing Time: Led curing lights dental provide a higher intensity of light output compared to halogen lights, resulting in faster curing times for dental materials like composite resins. This means dental procedures can be completed more efficiently, reducing the time patients spend in the chair.

●Energy Efficiency: Led curing lights dental are more energy-efficient than halogen lights. They consume less power while delivering the necessary light intensity, making them cost-effective and environmentally friendly.

●Longevity: LED bulbs have a significantly longer operational life compared to halogen bulbs. This reduces the need for frequent replacements, saving on maintenance costs.

●Reduced Heat: Led curing lights dental produce less heat during use, which is more comfortable for patients and reduces the risk of potential damage to surrounding tissues.

●Wavelength Specificity: Led curing lights dental can be designed to emit specific wavelengths, such as the blue spectrum, which matches the absorption peak of the photoinitiators in dental composites. This ensures efficient curing and reduces the risk of incomplete polymerization.

●Portability and Ergonomics: Led curing lights dental are often lightweight and designed with ergonomic features, making them easy for dental professionals to handle during procedures.

By the way, the use of the types of the curing lights determines the specific clinical needs, so you don’t have to over-emphasize the use of the led curing light.

Why Do Dentists Use Yellow Light?

As a matter of fact, the yellow light in the dental curing lights is to prevent the premature curing of the dental composite.

Why Do Dentists Use Blue Light?

The blue light in the dental curing light is used to active and harden the filing materials.


Finally, each type of dental curing has its pros and cons and still plays an important role in dentistry. As technology advances, newer and even more efficient curing light options may become available. Therefore, we also still need to keep our eyes on the development of dental equipment.
