Antimicrobial Activity of Laser Systems in Endodontics

Endodontic success is dependent on disinfection and debridement of the canal system. It has been well documented that bacteria and their products contribute greatly to the occurrence and development of pulpal and periapical diseases. Additional disinfection measures are necessary in order to eliminate and neutralize the microorganisms and their toxins. Laser has been examined as adjunct to current disinfection method and is an effective tool for killing microorganisms. Once our knowledge of optimal laser parameters for each treatment is complete, lasers can be developed that will provide dentists with the ability to care for patients with improved techniques.
