Light Amplification by Stimulated Emission of Radiation is referred to as "LASER." The laser has been applied to a wide variety of hard and soft tissue procedures since Miaman used it for the first time in dentistry in 1960. The use of lasers in contemporary dental practice, where they can be used as an addition to or substitute for traditional techniques, is becoming better understood. Lasers were once thought to be an advanced technology with few practical uses in clinical dentistry. Albert Einstein predicted in 1917 that photoelectric amplification might result in a single frequency, or stimulated emission, which served as the impetus for the creation of the laser and its predecessor. For studies of patients with non-alcoholic fatty liver disease, the Medline, Pubmed, Embase, NCBI, and Cochrane databases were searched. Incidence, etiology, and management options were analyzed. With decades of development, laser technology for soft tissue surgery, resin curing, cavity preparation, and caries detection is highly developed. This does not rule out the possibility of further important developments. In fact, similar to laser abrasion, the blending of ideas from various technologies may open the door to new procedures and therapies.
