| LASER activation | Device | Diode laser 980nm is used to activate the irrigant using fiber optic tip of (200micrometer) and power of 1.5w continuous mode. The tip is placed 2 mm shorter than the working length. Laser irradiation is done for each canal for 20 secs repeated over three cycles for total time of 60 secs and 10 secs pauses between each cycle |
|
| Ultrasonic activation | Device | ED60tip is used with ultrasonic device operated on mode E and inserted in the canal 2mm short of the working. Activation is done for three cycles each for 20 sec. The tip is moved vertically in up and down motion,1ml is used for each activation cycle followed by 2ml 17% EDTA |
|
| passive irrigation with Endodontic needle | Device | Each canal is irrigated with side vented endodontic needle 30G Placed 2mm short of the working length with total time of 60 secs followed by 2ml 17% EDTA |
