The health of human teeth is the key to their longevity. If you comply with oral hygiene, visit a dentist on time, and not only when “something hurts”, but also for prevention, then your smile will remain with you for many years. Did you need to put a seal? Here it remains to hope for the professionalism of the doctor, as well as for the quality of the materials used for tooth restoration.
Curing dental lamp, as well as other specialized equipment and tools are the best dental assistants. And therefore, he must know what types of lamps for polymerization are and what to look for when choosing.
What is such a device?
Just a couple of decades ago, dental treatment in dental clinics was carried out at a fairly simple level. Neither equipment nor accessible materials allowed for a high-quality restoration of teeth - fillings often fell out, and artificial teeth were immediately evident. But with the expansion of modern technology, it has become possible to carry out not only durable dental fillings, but also tooth extension so that it is identical to the natural one. As the main material used by dentists today, a photocomposite acts, which hardens, falling under a light energy source. And this light emits, the wavelength of which is 470 nm, a polymerization dental lamp.
What is this device? We will try to answer this question. A lamp for the polymerization of teeth is a special device that is used in dental practice to ensure the hardening of photopolymer fillings, insulating gaskets, sealed materials and adhesive systems.
Types of devices
There are several types of lamps designed for the effective polymerization of materials used for the restoration of human teeth. Knowing some of the differences, it will be easier for the dentist to make a choice in favor of a particular device. So, they are of the following types:
- Halogen - glow a tungsten filament located in a light bulb with a halogen gas, forming light. In order for useful light to stand out, an interference filter is provided in the device. This model is cheaper than LED, but such a device has disadvantages: it is not wireless, and in it you need to regularly change the light filter and incandescent lamp.
- LED light. In them, the generation of light inside a semiconductor crystal is carried out using the energy of excited electrons. LED lamps are by far the most popular. They have a fast coefficient of action, they have no filter, their efficiency is high. However, they do not radiate heat. Another advantage - these devices are wireless, which is very convenient for the dentist. How much does a dental polymerization lamp cost? Its price varies between 5000-20000 rubles. Used models are also included in this range.
- Plasma-arc. In such devices, powerful radiation is obtained through the use of a high-voltage arc in a gaseous sphere, rarefied between the electrodes.
- Laser Their light is produced by the transition of electrons from an unstable state to a stable one.
It can also be noted that the last two types of lamps are not widespread among dentists, as they “seat” the composite. If you need a curing dental lamp, we recommend that you pay attention to the second option.
What to look for when choosing a device?
Let's see what criteria you should pay attention to if you decide to choose a curing dental lamp. China, by the way, also produces decent models. So:
- When buying, pay attention to the emitter, namely its convenience and lightness. After all, you will have to work with the device for a long time.
- If you are inclined to favor non-LED mechanisms, then pay attention to what noise comes from the fan. If it is too tall, you will not be comfortable working.
- Luminous flux density. The higher it is, the faster the photopolymer material hardens.
- Is the model wireless. For some dentists who carry out constant treatment of patients and their records, the polymerization dental lamp must be wireless, because this is the key to comfort during long-term work. But if the presence of wires is not an obstacle, you can pay attention to another option.
Popular models
It is worth mentioning separately about the popular, relatively inexpensive, but high-quality models. These are lamps such as Dr's Light, equipped with a teeth whitening function, WBL-100, LED Skylight, which has three operating modes, and a curing dental lamp, which is compact in size.
