An overview of lasers in the field of dentistry

Laser is the acronym which means ‘Light Amplification by Stimulated Emission of Radiation’. They have showed a very broad way since 1971 (Albert Einstein described the theory of stimulated emission during this year). The advancements and achievements of lasers in the different fields of medicine and dentistry are playing a significant role in the wellbeing of patients. Since the last two decades, there has been an explosion of different research studies in application of lasers. In different fields of dentistry lasers are used in hard tissue application, for prevention of caries, bleaching purposes and restorative purposes i,e both removal and curing, cavity preparation, treatment of dentinal hypersensitivity, growth modulation and for finally for diagnostic purposes, however the soft tissue application includes wound healing, removal of hyperplastic tissue (uncovering of impacted or partially impacted tooth), photodynamic therapy for various malignancies, photo-stimulation of herpetic lesion. Different use of the laser proved to be an effective tool to increase effectivity, efficiency, specificity, ease, cost and comfort of various dental treatments.
