Laser applications in endodontics: a review article

Abstract

Abstract Background Different types of dental laser can be used instead of the traditional hand and rotary files in root canal treatment with highly acceptable performance. Laser devices emit an intense and focused light energy, which interacts with biologic tissues, for pulp removal, shaping and cleaning the dentinal walls to be finally sealed with gutta-percha. Various laser devices with different wavelengths such as CO2, Er:YAG, Nd: YAG and Diode present the best laser–tissue interaction. Lasers in root canal treatment show more advantages than traditional treatment. Laser is more accurate than conventional root canal treatment that allow minimal removal of healthy dentinal tissue. Lasers have anti-bacterial effect by reduction of more than 99.7% bacterial counts for root canal sterilization. Laser provides less bleeding, inflammation, pain, discomfort and infection than conventional procedures. Laser treatment of root canals results in a good sealing of gutta-percha to root canal walls to prevent infections. Conclusions Laser application is comfortable to the patients by removing the disturbing sounds of drills and decreasing the need for local anesthesia. It decreases the need for suturing in endodontic surgery due to better hemostasis, thus getting clean and well-sealed surgical wounds.
