Both adult and pediatric patients should have equal access to curing lights, and those lights should be able to move into the proper positions without damaging the composite. For a successful treatment, it is recommended to use a curing light with an intensity between 750 and 2000 milliwatts per square centimeter.

Using a curing light with a wattage greater than 2,000 may result in overheating and energy waste, and the composite will not cure any more quickly as a result. Dentists should rely on the composite manufacturer’s recommended curing times rather than those provided by the light manufacturer, even when higher wattages are visually appealing.

Have you seen a blue light shining down on you from the ceiling of the dentist’s office? Many people are confused about the purpose of this light and worry that it may do harm. A curing light, or blue light, is used to harden white fillings.

In the dynamic world of dentistry, the advent of light-cured dental materials has revolutionized various procedures, making them more efficient and effective. This article delves into the fascinating realm of dental light cure, exploring its purpose, features, leading brands, and future trends. Whether you’re a seasoned dental professional or a student in the field, this comprehensive guide will shed light on everything you need to know about dental light cure.

Understanding Dental Light Cure

Dental light cure refers to a technique used in dentistry that involves the use of a specific type of light to harden or set dental materials such as composites, adhesives, cements, and sealants. This process is scientifically known as polymerization. The light used in this process is typically blue and falls within a specific wavelength range, which is most effective in curing dental materials.

Types Of Curing Lights

There are several types of curing lights used in dentistry, each with its unique characteristics and applications:

  • 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 life, and by today’s standards give off the most consistent curing by its 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 it can work with due to its 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 consists of having an aluminum oxide vessel containing high energy xenon gas under 150 psi. These curing lights produce focused beams and typically are designed within large base units and small tips for the desired effect. However, it lacks the ability to cure all materials and can be quite expensive.

  • Argon Laser – Argon lights generate light through applying energy to the atoms of argon gas, where 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.

Features of Dental Light Cure

Dental light cure units come in various forms, but they all share some common features. These include:

  • Range of Wavelengths: The light emitted by these units falls within a specific wavelength range, typically between 400 and 500 nanometers. This range is most effective for curing dental materials.

  • Light Intensity: The intensity of the light is a crucial factor in how quickly the materials cure. Most units allow for adjustable intensity levels to suit different needs.

  • Design and Ergonomics: Dental light cure units are designed to be easy to handle and operate. They often feature ergonomic designs and may be corded or cordless.

  • Modes and Settings: Many units come with different modes and settings, such as ramp mode, which gradually increases the light intensity, and pulse mode, which emits light in pulses.

  • Built-in Timer: A built-in timer is a common feature that allows for precise control over the curing time.

The Role of Dental Light Cure in Dentistry

The dental light cure has a significant role in modern dentistry. It is used in various dental procedures, including:

  • Filling Cavities: Dental light cure is used to harden composite resin fillings in cavities.

  • Bonding: It is used in bonding procedures to attach veneers, crowns, or bridges to teeth.

  • Orthodontics: In orthodontics, dental light cure is used to set the adhesive that holds braces in place.

  • Sealants: Dental light cure is used to harden sealants that protect the chewing surfaces of teeth from decay.

Dental Light Cure: Brands and Models

There are several leading brands and models in the market that manufacture dental light cure units. One of the standout brands is CICADA, known for its high-quality dental equipment. CICADA offers multiple dental light cure units, each designed to meet the varied needs of a modern dental practice.

Dental Light Cure: A Buyer’s Guide

When purchasing a dental light cure unit, several factors should be considered. These include:

  • Type of Light: Dental light cure units can use halogen, plasma arc, or LED lights. Each type has its pros and cons, and the choice often depends on the specific needs of the dental practice.

  • Intensity and Wavelength Range: The intensity and wavelength range of the light can affect the curing time and effectiveness. It’s important to choose a unit that offers the right balance for your needs.

  • Ease of Use and Ergonomics: The unit should be easy to handle and operate. Consider factors like weight, balance, and corded or cordless design.

  • Durability and Maintenance: The unit should be durable and easy to maintain. Consider the construction material and the reputation of the manufacturer.

  • Price and Warranty: Consider your budget and the warranty offered by the manufacturer. Remember, a higher price often means better quality and durability.

The Future of Dental Light Cure

The field of dental light cure is continuously evolving, with new advancements and innovations emerging regularly. Some of the future trends in dental light cure technology include:

  • Smart Dental Light Cure Units: These units can adjust the light intensity and wavelength range automatically based on the type of material being cured.

  • Wireless Dental Light Cure Units: Wireless units offer greater flexibility and convenience. They are expected to become more common in the future.

  • Eco-friendly Dental Light Cure Units: As sustainability becomes more important, manufacturers are looking for ways to make their units more energy-efficient and eco-friendly.

What Does The Blue Light Do?

The blue light sets fissure sealants, fillings and cement in a matter of seconds. When fillings are placed in the tooth they are very soft so they can be moulded to the correct shape by the dentist. When the dentist is happy with the shape of the filling they will set it with this light. The blue light makes the filling go rock hard and strong enough to chew on. The blue light is also used when having braces fitted to set the cement which holds the brackets on your teeth.

Is The Curing Light Dangerous Or Harmful To Look At?

The dental curing light is a very strong blue light. It it not a laser or a UV light so it will not cause any damage to your teeth or gums. The only danger is if you look directly at the light for too long. Similar to how your eyes will hurt if you look at the sun for too long. Dentists and assistants are advised not to look at the light for long periods of time. There are two types of curing lights used by dentists. There is a halogen curing light and an LED curing light. Most modern curing lights are LED as they do not overheat like the halogen curing lights do. The only danger with the halogen light is that the heat it produces could potentially hurt the pulp of the tooth or the soft tissues in the mouth. Although this is possible, it is very unlikely. The majority of dentists use LED curing light these days.

What Does The Orange Shield Do?

The orange shield is a filter so that your dentist and assistant can still look in your mouth without the strong blue light hurting their eyes. The light is okay to look at for a few seconds but it’s not nice for dental staff to look at for too long.
