There are several techniques to manage heat from high intensity curing lights including For example, FUSION 5 at plasma power mode feels hot quicker than at pulse power. If it does not feel anything on your finger right away, it is a low power LED light. The higher the optical power, the hotter it is going to feel on your finger from optical absorption of your skin. 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. In general, the higher the intensity of curing light, the more heat it generates. With a typical curing time of 5 seconds, it easily delivers over 10J/cm2 which is the typical energy required for composite cure. ![]() Check on the composite hardness on the bottom side to make sure that it is hard enough after your typical curing time.įUSION has been proven to deliver the most energy in a given period of time. Test the composite outside of the mouth on a piece of paper or even better on a short tube (e.g. Use curing cap as the anchor to the cavity for stable positioning and direction. To operate correctly, make sure that the light is directed at the composite as close as possible. 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.įour core variables of proper curing are:įUSION has been proven to be the best curing light in power, ease of use and reliability. ![]() How much time does it take to cure with FUSION? 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. 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.įUSION 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. 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. 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. How can I measure the power of curing light? The study suggests that these low-cost curing lights lack the desired consistent and depth of cure.įUSION curing lights have been consistently rated as one of the best curing lights on the market through the past 11 years through 5 generations. In particular, it demonstrated online budget curing lights have not only small light tip, but also very inconsistent and unstable light output. The results can be very different not only short term from sensitivity and bonding failures but also longer term.Ĭlinicians Report has performed many independent studies on varies curing lights. ![]() The major performance parameters are light intensity, tip size, beam uniformity (homogeneity), wavelengths and beam dispersion. Lights are different not only from their performances but also their constructions and service supports. This is explained in detail in "Light Curing Guidelines for Practitioners" from a group of experts in the field of dental restorations.
