Clinical Trial Summary

The aim of this study was to evaluate the effect of continuous rotation and reciprocation kinematics on post operative pain and difference in substance P levels in patients with irreversible pulpitis with symptomatic apical periodontitis. Twenty patients were randomly distributed into two groups; Continuous Rotation group(n=10): received mechanical preparation using EdgeEndo x7 rotary system (Albuquerque, New Mexico, USA), while Reciprocation group(n=10): received mechanical preparation using EdgeOne Fire reciprocating system (Albuquerque, New Mexico, USA). Apical fluid(AF) samples were collected, and substance P (SP) levels were measured using radioimmunoassay and postoperative pain was measured using Numerical Rating Scale (NRS) preoperatively, at 6h, 12h, 24h, 48h and 72h.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	difference in substance P levels	tested by radioimmunacy (ELISA)	pre-operatively and after 5 days at the beginning of the second visit
Primary	post operative pain levels	Numerical Rating Scale was used to assess pain where 0 is no pain and 10 is the worst possible pain	pre-operative, after 6 hours, 12 hours , 24 hours, 48 hours, 72 hours
