ABSTRACT


Introduction: Postoperative Pain Has Been Thought To Vary According To The Instrumentation Kinematics. The Objective Of The Present Trial Was To Compare The Incidence Of Postoperative Pain And The Amount Of Analgesic Intake After Using Reciproc Or One Shape Nickel-titanium Systems For Root Canal Instrumentation. Subjects And Methods: Fifty-four Patients With Symptomatic Irreversible Pulpitis Were Assigned To 2 Groups According To The Root Canal Instrumentation Technique, Reciproc (VDW, Munich, Germany) Or One Shape (MicroMega, Besan�on Cedex, France). Treatment Was Completed In A Single Visit. At The End Of The Visit, Participants Were Asked To Rate The Intensity Of Postoperative Pain On The Numerical Rating Scale At 6, 12, 24, 48 And 72 Hours. Participants Were Also Given Ibuprofen 400 Mg To Be Taken In Case Of Intolerable Pain And Asked To Record The Number Of Analgesic Tablets Taken At These Time Points.

Results: No Statistically Significant Difference Was Found In Terms Of Incidence Of Postoperative Pain Nor The Analgesic Intake At The Assessed Time Points.

Conclusions: Instrumentation Kinematics Had No Impact On Intensity Of Postoperative Pain.
