dentist light is used to rapidly cure resins in a safe and effective way. Resins have become an integral part of dental health as they are used as restorative materials, adhesives, as well as sealants for various dental procedures. The curing light is produced by a curing lamp and which produces visible or ultraviolet light depending on the intended use. There are various types of resins that are used for dental work; for this reason, different types of lamps are used depending on the type of resin to be cured.
The most important component of the dental ultrasonic scaler is the light source and which can either be a halogen lamp or a light emitter diode commonly referred to as LED. The light source should be capable of precisely targeting light to the desired location thus increasing the efficiency of the curing light. The effects of the dental curing light as well as the use of other compression techniques helps in boosting the adhering properties of the dental resins, and which makes the resin filling long-lasting. Halogen lamps were commonly used for dental curing purposes in the past but over the years advances in technology have popularized the use of the LED, plasma and UV light lamps.
Dental turbine, which takes approximately two hours to charge a discharged battery, has a run time of 45 minutes. A visible green light indicates the unit is charged.
Audible beeps occur every two seconds during operation, and the light timer can be adjusted between two and 20 seconds. A radiometer that provides the user with a numerical reading of the light intensity is optional. The Cure TC-CL II can run in a high mode for curing materials or low mode for curing near the pulp and minimize polymerization shrinkage.
The fast standard halogen curing lamp has been widely accepted among dentists. Even if the curing light is more expensive than the standard halogen dental led curing light, the reduction in curing time when using this device compensates for the extra cost over a period of time. The PAC curing lights came into the market about six years ago. Back then dentists could not believe just how quick these curing lights restored the resins. On average their recommended curing time is roughly 3-5 seconds. However, a PAC curing light costs three to four times as much as a standard halogen dental curing light.
With the introduction of high power LEDs, blue LED light is now used as a source for curing light technique. High power LED (3 or 5 Watts) is used as the light source which emits blue light in the wave length of 430-485 nano meters. Light intensity can reach 1000 milli watt per cm2 and the timing of curing usually 10-20 seconds can be set using a timer. The LED lamp hardly generates heat so the operation is comfortable. The light output can be adjusted as Fast, Ramp or Pulse depending on the requirements. Light activated dental resin is used to fill the cavity of tooth. It is translucent polymer that quickly hardens when exposed to specific light spectrums. The required wavelength of light depends on the chemistry of resin used. The light activated resin remains liquid form in normal light but when the light of a particular wave length is focused, the resin turns into a hard material which remains tight inside the cavity of tooth. Liquid form of resin helps to prevent the formation of air bubbles during filling.
