Abstract

Light Amplification by the Stimulated Emission of Radiation, or LASER, is what the phrase refers to. Since Miaman used the laser for the first time in dentistry in 1960, it has been applied to both hard and soft tissues in a variety of ways. There has been a huge increase in laser application research investigations during the past 20 years. While the laser is used on hard tissue, soft tissue applications include wound healing, the removal of hyperplastic tissue to reveal impacted or partially erupted teeth, photodynamic therapy for malignancies, and photo stimulation of herpetic lesions. Hard tissue applications include caries prevention, bleaching, restorative removal and curing, cavity preparation, dentinal hypersensitivity, growth modulation, and diagnostic purposes. The laser was found to be a useful instrument for improving the dental procedure's effectiveness, specificity, simplicity, affordability, and comfort.
