Lasers--panacea or paradox?

The first lasers were quite unsuitable for dental use, but the last 30 years have seen the development of a variety of lasers which allow dentists to cut soft tissue without bleeding, remove caries, cut cavities in teeth (usually without pain), cure composite resins rapidly, weld metals with precision, desensitize teeth, sterilize exposed pulps and tissue surfaces and treat skin lesions. Future research may explain why 'soft' lasers appear to promote healing and alleviate joint and muscle pain. There are now many published reports in refereed dental journals covering the various aspects of laser dentistry. Dentists interested in lasers, or who are considering purchasing one should read the relevant literature and consult their Association and colleagues before making a purchase.
