Lasers have emerged as a valuable adjunct in endodontics, enhancing both the precision and efficacy of various procedures. The term LASER stands for "Light Amplification by Stimulated Emission of Radiation," and different types of lasers are employed in endodontics based on their wavelength, interaction with tissues, and clinical purpose. Commonly used lasers include Nd:YAG, Er:YAG, Er,Cr:YSGG, diode, and CO2 lasers. In endodontic procedures, lasers are primarily used for disinfection, root canal cleaning and shaping, pulp capping, pulpotomy, and apicoectomy. The laser's ability to penetrate...
