Postoperative Pain of Rotary Versus Reciprocating Motions of Two Single Files

Minia University260 enrolled

Overview

An equivalent parallel randomized clinical trial was approved by the local University Committee of Ethics. 260 children with necrotic primary molars were allocated into 2 equal groups (82 children per group). The participants were allocated into two groups; group "1" teeth were instrumented with OneShape rotary system (Micro Mega, Besancon, France), and group "2" teeth were instrumented with WaveOne Gold reciprocating system (Dentsply Maillefer, Ballaigues, Switzerland). Postoperative pain was assessed using a four-point pain intensity rating scale adopted from Wong-Baker FACES (WBF) pain scale . The face scale consists of four faces with a brief title describing each face representing a scale from the first face (score 1), second face (score 2), third face (score 3), and forth face (score 4) 3. Postoperative pain was assessed at 6 six time intervals (at 6, 12, 24, 48, 72 hours and one-week).
