FAQ - Monet Laser Curing Dentistry
Features of laser light make it more efficient and accurate than LED light.
- Laser light is in a collimated beam, that is, the light beam is straight, it does not disperse or converge over distance. The Monet does not expose oral soft tissue with light spillage. You only affect the area you’re aimed at.
- The spot size and the energy remain consistent regardless of the distance the light is from the target.
- There is consistency across the beam. There are no weak spots from dispersion nor hot spots. . The beam of light is designed to penetrate to the bottom of the composite material, and exposure is only 3 seconds so there is minimal threat to the pulp of the tooth.
The spot size of the Monet laser curing light beam is 11mm
The Monet laser curing light cures virtually all composites. It has been tested with light and dark shades of the most commonly used composites and performs as well or better than the leading LED curing lights. Of course, with any curing light it is a good idea to test its performance on a small piece of the composite you will be using.
There’s actually 2 possible meanings to this question. Here are answers to both.
- Does the tip or housing of the Monet feel hot to the touch?
No. The laser source for Monet is inside the handle, so there are no electronics or light sources in the tip. Many LED curing lights have the LED right at the very tip. The electronic component generates some heat and because the tip is very small, this heat reaches the outside surface quickly. The Monet unit doesn’t have this issue.
- Will I feel heat if I aim the beam at my skin or a fingernail?
Yes. WE STRONGLY URGE YOU NOT TO DO THIS with the Monet laser or with any curing light or laser light. Although the light from Monet doesn’t carry any heat, once the light reaches a surface that blocks the light, that energy gets absorbed and converted to heat. So actually, the heat you feel isn’t from the light itself, it’s from your own skin heating up because it’s absorbing the light. Again – DO NOT ATTEMPT THIS. Whether it’s the Monet or an LED curing light, the high intensity blue light can cause photodynamic tissue reactions – almost like a sunburn. The experience that you would feel on your hand is different than that on the composite material because the composite is made of different materials that do not absorb light to create heat.
The same safety measures should be taken with Monet as with any laser. You may not be familiar with laser safety procedures as these are not always indicated for LED curing lights. The dentist, the patient, and anyone else in the room should wear the appropriate protective glasses. The laser should not be activated until it is in the patient’s mouth over the area to be cured. When used according to the instruction manual provided with it, the Monet laser will provide safe and reliable results.
No, but this does not negatively affect the Monet unit's ability to cure.
Consider a broadband LED light which generates sufficient energy for photoinitiation of a compound in a composite or adhesive. At a given wavelength, the LED light actually produces a relatively low amount of energy, necessitating the light to be broadband to provide the energy for photoinitiation.
Lasers, by nature, emit light in a narrow bandwidth, but generate a lot of energy within that bandwidth. The laser light is absorbed by the photoinitiator, and the high level of energy compensates for the narrow bandwidth of light.
The curing test is the proof, and as we stated, the Monet laser curing light cures the composites.
No in both cases. The aiming beam has a power output less than 3mW; it is not intense enough to start curing the composite or adhesive.
This depends on the composite. With the common brands of composites tested, a full cure to a depth of up to 8mm can be achieved in a single 3-second cure except for darker shades of composite, which block the light from penetrating as deep and may require a longer time. It’s always a good idea to test the performance of the Monet or any curing light on a small piece of the composite and to err on the side of caution by placing a few thinner layers and curing each layer sequentially.
No. The battery provided with the Monet unit is carefully selected to run the laser source inside. Other batteries may not have the ability to run the Monet unit correctly, or could be overwhelmed and create a risk of damage or injury.
No. Because the light is collimated and does not spread out over distance, the Monet would not cover even a portion of the arch. Using the Monet would be inefficient, and the intensity of light may have unintended results on the whitening product used.
