It is no doubt that light-curing is a most viable concept in modern dentistry and it is also the case that new forms of this technique have been introduced, even as some old formats are still be used by some practitioners. Confusion has subsequently arisen as to what form of curing light is most ideal, given that the techniques available now all seem to work adequately. In this regard, a sound conclusion is such that the choice of curing light should be informed by how well or not a certain light’s features suits individual dentists requirements best. Here are some of the more popular lights now in use:
a.Conventional halogen curing lights – These are known for their ease of use and general reliability. Some of these lights are available at prices cheaper than what is needed for other systems. In their operation they produce little or minimal heat. Their technology is quite basic and nonthreatening.
However, many of these devices require house electricity to operate and they are quite cumbersome in size. Their lamps output decreases with usage and frequently calls for replacement though they are affordable.
b.Enhanced halogen lights – These systems make for increased curing intensity and much faster resin curing. They use light guides that decrease in size upon exit from the curing light and the technology they make use of is known and proven.
They are however known to produce heat during curing and some brands have their curing tips being narrower than is the case for conventional lights. They also share similar disadvantages with conventional lights in terms of house electricity requirements and cumbersomeness.
c.Light-emitting diode lights – These are relatively modern Curing Light systems which give a host of advantages like noiseless operation, short curing times – approximately 10-20 seconds, zero heat generation during curing, use of diodes that last long and seldom need replacement, and their being lightweight, compact and cordless.
They however produce relatively low intensity and have slower curing times compared to PAC lights as well as a couple of enhanced halogen light systems. They are more expensive than conventional halogen lights and their technology is still being improved on.
d.Plasma arc curing lights – Despite allegations that these cause damage to resin-based restorations and to tooth preparations, they have been successfully used by many practitioners on multiple occasions. They make for short curing times and subsequently significant savings.
However, this curing light concept is certainly more expensive than any of the aforementioned options. During curing they produce considerable amounts of heat that must be reduced or controlled by air cooling and proper cure timing respectively. Their lamps, though useful for many hours, are quite costly to replace upon wear and damage. These gadgets are also heavy and cumbersome.
