Abstract
Dental lasers have been commercially available for several decades. Laser are an exciting technology, widely used in medicine, kind to tissue and excellent for healing. It has provided us with a potential alternative to simultaneously remove the diseased soft tissues, target the micro‑organisms as well as stimulate wound healing. They generate a precise beam light concentrated with energy. Each laser technology is engineered to perform specific special functions without changing or damaging the surrounding tissues. In 1960, Maiman introduced “light amplification by stimulated emission of radiation” (LASER) using Einstein’s theories about the stimulated emission. Since then, different lasers, such as diode, CO2, Nd: YAG, Er: YAG, and Er, Cr:YSGG have been developed and within a span of few years, it has been of great use in dentistry. They have been used in initial periodontal therapy, surgery and also in implant treatment.
