Correlation Between Postoperative Pain and Apical Extrusion of Different Irrigation Activation Techniques

Ain Shams University32 enrolled

Overview

The aim of this clinical trial is : To evaluate effect of different techniques of irrigant activation: 1. LASER activation 2. sonic activation 3. ultrasonic activation 4. passive needle irrigation On: 1. Postoperative pain in vital teeth (Randomized controlled trial) 2. Amount of apical extrusion (In vitro study) Participants will describe their preoperative pain and postoperative pain level at fixed time interval Research will compare postoperative pain accompanied with different irrigant activation techniques and correlate it to amount of debris extrusion

Interventions

sonic activator

Polyamide EDDY tips 28mm long is inserted in the canal 2mm short of the working length operated at 6,000 Hz. Activation is done for three cycles each for 20sec. The tip is moved vertically in up and down motion, 1ml is used for each activation cycle followed by 2ml 17% EDTA20

LASER activationDEVICE

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 activationDEVICE

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
