Aim: The aim of this study was to compare the effectiveness of rotary instrumentation over manual instrumentation with ultrasonic irrigation on incidence, duration, and intensity of postendodontic pain (PEP).
Subjects And Methods: Eighty patients, with asymptomatic irreversible pulpitis in maxillary anterior teeth, were selected and treated with single-visit endodontic treatment. Patients were randomly divided into 2 groups (40 each), Group A (K files using step-back technique) and Group B (ProTaper Next using crown-down technique) along with passive ultrasonic irrigation. Patients were recalled, examined, and asked to fill up questionnaire after 24 h, 48 h, and 7 days. On the basis of response given in the feedback forms, incidence, duration, and intensity of PEP were evaluated.
Results: Statistical analysis of the data was carried out using Chi-square test, and level of significance ( < 0.05) was evaluated. More incidence of pain was noticed in Group A when compared with Group B. Significant difference found between two groups ( = 22.759; = 0.001). There was also statistically significant difference between two groups at different time intervals.
Conclusion: Both instrumentation techniques under investigation cause PEP. The incidence of pain was more in manual technique than rotary technique. The duration of pain was higher in manual group than rotary group at different time intervals.

Objective: To compare the effect of syringe irrigation technique, passive ultrasonic activation technique, EDDY activation technique and Er,Cr,YSGG laser activation technique on smear layer removal in root canals .
Methods: Forty mandibular first premolars with single canal were collected from patients in Qingdao Stomatological Hospital affiliated to Qingdao University. After root canal preparation with ProTaper Universal to F3, they were randomly divided into four groups (n = 10) according to different activation irrigations for the final washing: syringe irrigation (SI), passive ultrasonic activation (PU), EDDY activation (EDDY) and Er,Cr,YSGG laser activation (YSGG).

Background The structural properties of dentin, including its microhardness, can be affected by exposure to endodontic irrigating solutions and ultrasonic activation. Aim The current study aimed to assess the effect of three different irrigation regimens, with and without ultrasonic activation, on the microhardness of the dentin. Methodology The research was conducted on 120 mandibular premolars randomly divided into four groups (n=30) based on the irrigation regimen, with each group further divided into two subgroups (n=15).
