Abstract
Aim: The aim of the present study was to clinically compare the incidence and intensity of postoperative pain after root canal preparation using (Twisted file) with Adaptive motion and (M-Pro) with continuous rotary motion in mandibular premolar teeth with symptomatic irreversible pulpits. Methodology: Forty-eight patients suffering from symptomatic irreversible pulpitis in mandibular premolars were treated in a single visit root canal treatment using TF and M-Pro for the preparation of the root canals, according to each patient group. The patients were classified into 2 groups according to the rotary system used: group A (TF Adaptive) and group B (M-Pro). The patients were asked to record their pain intensity at 6, 12, 24 and 48 hours postoperatively. Data were analyzed using chi-squared and Mann{u2013}Whitney U tests. Results: The results showed that there was no statistical difference between the two groups regarding patient age, gender, tooth type, and preoperative pain except for the prevalence of postoperative pain. There was a statistically significant difference in the postoperative pain reduction between the two groups at 24 hours as it was higher in the M-Pro group than in the adaptive TF group.Conclusions: Within the limitation of this study it was concluded that both files are considered reliable instruments for root canal preparation inducing a normal range of postoperative pain
