सार

Chemical expansion techniques are integral to the success of root canal therapy, enhancing cleaning, shaping, and disinfection. This article explores prominent methods including sodium hypochlorite irrigation, ethylenediaminetetraacetic acid (EDTA) chelation, passive ultrasonic irrigation (PUI), sonic irrigation, and laser-activated irrigation (LAI). Sodium hypochlorite's antimicrobial properties dissolve organic matter, while EDTA chelates calcium ions, removing the smear layer. PUI utilizes ultrasonic energy for enhanced debris removal, while sonic and LAI employ sonic and laser energy, respectively, to improve irrigant dispersion. Understanding these methods enhances treatment efficacy and patient outcomes.
