Abstract:

Bacterial elimination within root dentine is important for the success of endodontically treated teeth. Pulsed Laserenhancement of EDTAC has previously been shown to increase removal of smear layer and enhance debridement of the root canal spaces. Shockwave?s generated by lasers in fluid-filled root canal spaces generate shock waves that create shear stresses along the root canals walls, enhancing removal of the smear layer and biofilm. In addition, lasers may also provide a benefit through photothermal disinfection. However, effective and efficient laser activation of irrigants or medicament is root canals spaces depends on factors such laser wavelength, volume of fluid being lased, absorption characteristics of irrigants, laser energy settings, fiberoptic tip design etc. Our studies have shown that, careful selection of the correct laser wavelength, laser parameters and irrigants could provide a safe, efficient and rapid alternative to current endodontic disinfection protocols.
