Effect of Diode Laser Activated Irrigation Versus Ultrasonic on Post-Operative Pain in Single Visit of Necrotic Teeth
Effect of Diode Laser Activated Irrigation Versus Ultrasonic on Post-Operative Pain in Single Visit of Necrotic Teeth
the investigator intended to study the effect of laser versus ultrasonic in activation of
 irrigation in post operative pain of patients have a symptomatic necrotic teeth
the investigator will choose from patients entering clinic of endodontics in faculty of oral
 and dental medicine Cairo university who are eligible to the criteria.

 After the patients is found eligible,the patients will be randomly assigned to either the
 control (ultrasonic activated irrigation )or to the intervention ( diode laser activated
 irrigation) treatment done in both in single visit.

 At the end of treatment, patients will be asked to record post operative pain by NRS .
