The use of different wavelengths of lasers are becoming more or less indispensable for today’s clinical practice. Dental lasers can be used to cut, incise, and ablate hard and soft tissues. The inherent properties of laser light—such as selective absorption, coagulation, sterilization, and stimulatory effects on vital structures—make lasers the treatment of choice in certain clinical scenarios. Diode (810 nm, 940 nm, 980 nm, 1,064 nm), Nd: YAG (1,064 nm), CO2 (10,600 nm), Er: YAG (2,940 nm), Er, Cr: YSGG (2,780 nm), and potassium-titanyl-phosphate (KTP) (532 nm) lasers are the wavelengths used most commonly for soft tissue procedures. Given the proper use of lasers, it serves as a tool to perform precision dentistry.
The presentation aims to highlight the physics, properties, clinical indications, future applications and precautions to be taken while using lasers in clinical dentistry.
