As a dentist, we naturally need a curing light, but the problem we are facing often is how we choose. Today, we present precisely the means to choose a suitable curing light.
Today, the Dental Curing Light on the market mainly consists of two types according to the difference of light: the light is white and the blue light.
The previous, as the halogen lamp whose light source is a halogen bulb, produces white light and blue light obtained after wavelength of 400-500nm using the color filter, and the following as LED lamp or laser product itself blue light.
Halogen curing light produces a lot of heat during the processing of resin because its energy conversion efficiency is low, and a lot of energy lost as heat which will give a negative impact on the dental pulp. The laser light can set the exact peak at 468nm wave length that is most proper for most photoresists. But this technology is complicated and expensive. For the LED lamp, the scope of the wavelength is approximately 465nm to 470nm. This is exactly the blue light wavelength at which the resin is sensitive. Therefore, it is highly specific as the source of the curing light. More than 90% of the energy is converted into the pure blue light because there are no other colors produced, and then the LED lamp produces little additional heat. This is why we can avoid the negative impact of heat on the gum. This feature is so important to the curing light is also called LED cold light source.
When choosing a LED Dental Handpieces, we must take into account two factors: the LED overheating and rapid loss of light intensity over time. In fact, it is only the problem of overheating LED. To obtain the maximum output LED light, increase the maximum electrical power LED; however, if the electric current is too strong, it can cause overheating and more LED to greatly reduce the life of LED . The worst thing is to burn the LED.
