High-intensity LED Light-curing Units – The Heat They Produce

September 24, 2009

Ron Yapp, MS, John M. Powers, Ph.D. A primary goal for improvement of LED light-curing units has been to increase the light intensity – the thought being, the higher the intensity, the more rapid and more thorough the cure. Unfortunately, heat generation is a typical consequence of higher light intensity. The amount of heat that develops when light interacts with tooth tissue, resin composite or soft tissues is dependent on: the intensity of the light, how much of the light is reflected orRead more

Successful Light Curing – Not As Easy As It Looks

July 10, 2013

By Howard E. Strassler, DMD

Despite appearances that all curing lights are adequate, research has demonstrated that not all light-curing devices are equivalent! It involves specific devices and techniques, not all of which are equivalent. I have seen data for the evaluation of more than 145 different models of curing lights from 42 manufacturers. The prices of these lights range from $27-$4,900, with stated irradiance values ranging from 400-5,000 mW/cm2. While irradiance is the most common and easiest technique to measure curing light tip energy,Read more

Curing Lights

Are all curing lights the same?

All lights are not created equal. This is explained in detail in "Light Curing Guidelines for Practitioners" from a group of experts in the field of dental restorations. Lights are different not only from their performances but also their constructions and service supports. The major performance parameters are light intensity, tip size, beam uniformity (homogeneity), wavelengths and beam dispersion. The results can be very different not only short term from sensitivity and bonding failures but also longer term. Clinicians Report has performed many independent studies on varies curing lights. In particular, it demonstrated online budget curing lights have not only small light tip, but also very inconsistent and unstable light output. The study suggests that these low-cost curing lights lack the desired consistent and depth of cure. FUSION curing lights have been consistently rated as one of the best curing lights on the market through the past 11 years through 5 generations.

How can I measure the power of curing light?

Traditionally, curing lights are measured with "calibrated" radiometers on the light intensity or power irradicance in mW/cm2 (milliwatt per square centimeter), meaning the power in mW divided by the area of the light exposure in cm2. The radiometer, however, as "calibrated" as the manufacturers claimed, is not an accurate but a relative measurement instrument. The powers measured from radiometers are the irradiance level at the tip of a curing light, which does not indicate the power level received by composite inside a cavity.  Additionally, readings from radiometers vary significantly from their actual values. For example, a light measured on Kerr LED radiometer for 800 mW/cm2 displays 1066 mW/cm2 on Cure Rite, and 1280 mW/cm2 on Radii Radiometer as demonstrated by BlueLight Analytics, who has developed a highly accurate system called MARC that measures light intensity at all distances based on NIST calibrated spectrometer. FUSION Curing Lights are measured using both common radiometer and a precision NIST calibrated spectrometer system to ensure each production unit meets the criteria in our specifications. Because of the low dispersion from the patented FUSION lens system, you can be assured that FUSION delivers similar energy for both anterior and posterior standard restorations and more energy to bonding brackets than other LED lights on the market.

How much time does it take to cure with FUSION?

Typical curing time is 3 seconds for A3 or lighter shade with 2 mm thickness composite and 2 seconds for metal bracket/3 seconds for ceramic bracket bonding. The table below lists typical curing times for some common composite:
Manufacturer 3M Ivoclar Dentsply Kerr
Resin Brand Filtek Supreme Plus Heliomolar Tetric EvoCeram TPH3 XRV Herculite
Color/Shade A3E C6D A3 A2 A3 DY A3 YB
Cure Times (FUSION5, Plus or Grand) 3 9 3 3 3 3 3 3
Cure Times (FUSION S7) 10 30 10 10 10 10 10 10
Please use the CURE TIMES instruction from your Users Manual for further details.

What are the recommeded cleaning procedures?

    a)       FUSION parts are recommended to be cleaned and disinfected with a cleaning solution including Cavicide, Lysol, Isopropyl or Ethyl alcohol. Do not autoclave or ultrasonic.
    b)       Thoroughly wipe clean handpiece, Charging Base and Eyeshield with a soft cloth or tissue damped with the cleaning solution. Do not spray or soak. Disinfecting agents and liquid must not enter any openings on unit in particular Metal keypad.
    c)       Clean curing lens and electrical metal contacts using Q-tips slightly damped (do not soak) with the cleaning solution.
    Safeguard handpiece opening area, metal keypad, charging plug, and lens against liquid and sharp objects as this may cause electrical short-circuit, permanent optical damage or malfunction

Why do I need a White Light Head and what is an “Exam Tip”?

The DOE full kit comes with a White Light Head for oral illumination and transillumination. FUSION curing light can optionally add-on White Light Head. It accomplishes two goals:
  • Illumination to have side-by-side visual under fluorescence and enhanced white light illumination with the same magnification image
  • Transillumination for hard tissue oral health exam including dental caries, fractures, and root canal.
The Exam Tip (also doubles as a Tacking Tip for veneers/crowns/brackets with curing light head) is a disposable black 3mm opening tip that adapts and snaps into the end of the light head to cut down side light emission and guide the light propagation into a focused filament of light. It enables transillumination into interproximal teeth and improves contrast of visual exams on anterior, posterior and endo root canal.

How do I make sure that the composites/adhesives are cured properly?

Proper composite cures are essential to good restorations that not only avoid tooth sensitivity and rework/bonding failure but also longer lasting tooth/brackets and happier return customers. Four core variables of proper curing are:
  • Curing Light Selection
  • Correct Operating Technique
  • Proper Composite/Adhesive Selection
  • Deliver Required Energy
FUSION has been proven to be the best curing light in power, ease of use and reliability. To operate correctly, make sure that the light is directed at the composite as close as possible. Use curing cap as the anchor to the cavity for stable positioning and direction. Test the composite outside of the mouth on a piece of paper or even better on a short tube (e.g. 2mm) cut from your compule. Check on the composite hardness on the bottom side to make sure that it is hard enough after your typical curing time. FUSION has been proven to deliver the most energy in a given period of time. With a typical curing time of 5 seconds, it easily delivers over 10J/cm2 which is the typical energy required for composite cure.

Does FUSION cure all materials?

Yes. FUSION 5 cures CQ/PPD photoinitiator based composite. FUSION Plus and FUSION Grand cure all materials. It uses a smart patent-pending interchangeable 360 degree swivel LED light head that accommodates standard LED and broadband LEDs enabling it to cure all dental composites.

Does FUSION generate heat?

In general, the higher the intensity of curing light, the more heat it generates. Common test of an LED curing light by pointing it to the finger and feeling how hot it gets from the light tip tells you the power and quality of a light. The higher the optical power, the hotter it is going to feel on your finger from optical absorption of your skin. If it does not feel anything on your finger right away, it is a low power LED light. For example, FUSION 5 at plasma power mode feels hot quicker than at pulse power. There are several techniques to manage heat from high intensity curing lights including FUSION:
  • Use appropriate curing times. Limit the exposure time on a single tooth to below 3 seconds at a time, which has proven to be safe.
  • Do not place light in direct contact with unprotected gingival, oral mucous membrane or skin. Prevent heat accumulation with a rubber dam in place or apply Kool-Dam on the gingiva and surrounding soft tissue prior to curing.
  • Use technique of blowing air from an air syringe on the tooth being restored at the same time the resin is being cured as suggested by Dr. Gordon Christensen.
  • Use technique of placing a wet cotton roll directly on the tooth crown opposite the side of exposure to lesson temperature rise.
  • Use Pulse Power Mode to generate less heat if the users are more comfortable with it.
FUSION uses the most efficient passive cooling technology from aircraft aluminum as heat dissipator for LED. FUSION 5 is the most efficient curing light in that it generates the smallest amount of heat at the same energy than any other lights. It maintains its cool throughout the running times. Since light curing happens in short duration different from constant power sources such as computers, passive cooling without a fan is not only sufficient to ensure optimum performance without the annoying fan noise but also extends product lifetimes as is proven in the field for years. FUSION has a typical continuous run time of several minutes before self thermal protection and shutdown in Plasma Power Mode. Considering the extreme high intensity and perfect beam quality from FUSION light tip, typical composite curing time is just 3-6 seconds. The heat concern should not be an issue in normal clinical use.

What is Pulse Mode (Standard LED Power) Mode and when do I use it?

    Press and hold TM/PW Key for 3 seconds to set at Pulse mode (1300mW/cm2). Use this power mode to avoid heat. The matter of fact is, since FUSION is so much advanced and powerful, that the Pulse Mode (Half-power mode) is higher than or equal to actual power outputs of other leading brand LED curing lights with a similar tip size. For example, Demi with 11mm Turbo tip outputs 1100mW/cm2 power*. With its advanced heat cooling and power maintenance technology, FUSION generates minimum heat in Half Power mode and allows continuous operation without any interruptions.
    This mode is also used for extended running in oral exam and bleaching.
* Data from Reality Publishing: the Ratings - LED Curing Lights, Dec. 2008.

Is FUSION cordless and what is the benefit of cordless?

    Thanks to its superior technology and engineering design, FUSION has been independently proven as the smallest high power cordless light achieving performances in power and functionality no other corded or cordless lights can match. It takes the smallest counter space with a counter charger stand. Or it can sit right on your dental unit with optional dental unit charger holder. As powerful as it is, FUSION maintains consistent power through its battery run time.
    Cordless provides freedom of movement in patient treatment: allowing easier access without the cord dangling around and avoiding costly limitations to a single chair with room-to-room or chair-to-chair mobility. With proper design as demonstrated by FUSION, cordless avoids major long term failure in mechanical fatigue breakage from the cord.

How often does the battery need to be replaced and can the light be serviced?

    FUSION is designed using smart Lithium-Ion battery assembly with built-in micro-controller electronics for protection and smart charging. Together with the most reliable connection components with shock absorbing capabilities, it ensures the longest possible service time of close to 5 years in typical clinical uses. More importantly, it helps the clinicians avoid the hassles of dealing with the battery for a long time and offers the most efficiency in a professional environment.  Even in the case of a battery towards its end of life, users can easily replace the battery assembly with its screw-on connection.
    FUSION is modular in construction. User can easily replace the modular parts for field service. The light can be serviced by our manufacturing facility and authorized repair centers.

Since using the DentLight since 2013, I have found it to be very useful and convenient.  It is easy to use for curing, transillumination and exams with tissue fluorescence.  The option which I have found most helpful is the low level Red Healing attachment.   Following a long dental procedure, I simply switch from the curing to the healing attachment, and my patients are pleasantly surprised at the relief they feel in the TMJ area and muscles of mastication. I recommend the DentLight.


James T Smith Jr DMD, MAGD, FICOI

Very nice light, cordless and has never run out of power.

Nearly two years using the Fusion exclusively,  very nice light, cordless and has never run out of power.  High output, large tip, very dependable for me, and quite inexpensive. Excellent sleeves are available and easy to use.

raclro, Dentaltown

One of the best lights on the market.

Get the Fusion. One of the best lights on the market. I bond almost every restoration I do in my office. I refuse to jeopardize the quality of the bond, and thus my restoration and my reputation because I wanted to save a few hundred dollars and bought a cheapo light. The Fusion comes with a 2 mm tacking tip. The wand itself can be detached from the body and you can add other accesories, like a oral cancer detection light.

Once I bought 1 Fusion light, I bought a 2nd and was very happy.

I used Demetron for years.  Once I bought 1 Fusion light, I bought a 2nd and was very happy.  Demetron lights went into the transillumination mode only, after buying the fusion lights.

Everyone in the office loves them

I have 4 Fusion curing lights now for 4 months. No problems so far, quick cure, cordless LED, very small footprint for the charger, never run out of juice. Everyone in the office loves them.
Dr. Scott Leuene

FUSION shows the highest power density…

As a result of its low light dispersion, FUSION shows the highest power density at 5-mm tip distance among 22 LED lights and provides more than two times the intensity of many other LED curing lights at 10mm away from the tip.

“A Clinicians Guide to Light Curing”, Academy of Operative Dentistry, Annual Meeting, Feb. 2007.
Dr. Fred A. Rueggeberg

Very fast in curing, it really cuts time in half

This unit (FUSION 2008) is very simple to use, both the Dr. and myself can’t say enough good things about this unit- GREAT! … Power enough to get the job done in less time than our current light. … Very fast in curing, it really cuts time in half. … A great space saver. The unit is sleek, we like the nickel finish, classic look. The options are simple to use and the use for veneers for tacking time is wonderful

Blair Keck DDS

The light guides are excellent for tack and wave cementation of indirects

The dentlight Fusion is a cool little addition to your armormentarium: it is well made and neat looking and its small size allows it to reach difficult to access areas such as distal surfaces of second molars: this is particularly helpful for patients with restricted opening. The light guides are excellent for tack and wave cementation of indirects. I would unhesitatingly recommend this product .
Jason Smithson BDS

High Power… Tiny Footprint.

We’ve been impressed with the ease of use and most importantly, the intensity of the light resulting in a superior depth of cure. We’re also impressed with the low profile design that makes it easier to get the light parallel to the curing surface. It has a variety of curing cycles that will meet the needs of any user. The price is also right, giving you great value for the amount of energy it produces. This device comes with my highest rating. Dr. John Flucke

What influenced the way you practiced in 2010?

The curing of composites was enhanced through the use of DentLight’s Fusion and Kerr Dental‘s Demi Plus.

DentLight Fusion is a pen-grip-style curing light that has high output and can also be upgraded to a cancer detection aid. The Demi Plus continues the Dematron tradition with gun-style high-power curing. I am appreciating the faster curing and feeling better about the depth of cure from these lights.

I also reduced the size of the headlight on my loupes with a small LED light from DentLight called the Nano loupe light. The light was quite a bit brighter and smaller than my previous model.
