An overview of laser technology in dentistry

Laser technology was introduced in dentistry with a novel idea of overcoming some of the problems due to traditional treatment methods. After its first use in 1960s, laser technology has found its place in different aspects of dentistry field. The aim of this review is to explain laser applications and compare different types of lasers along with their advantages and disadvantages. A computer based search was done to study 135 articles in seven journals. Laser inherent properties make it the treatment of choice is some cases. Its main achievement is overcoming patient fear associated with conservative dental treatment. On the downside, cost is a big limiting factor in its use. Since the discovery of laser, its research has given different improved laser types, specialized for different targets, like new wavelength bands, maximum peak pulse energy, output power, minimum cost and maximum efficiency. Based on its development and its improved efficiency, laser technology application may revolutionize traditional dental treatment methods.
