Actual (reported)In this study the effect of different engine-driven nickel titanium (Ni-Ti) instrumentation systems (OneShape, Revo S and WaveOne) on postoperative dental pain in patients with asymptomatic teeth after a single-appointment root canal retreatment was evaluated.

Actual (reported)Change from Baseline in Postoperative Pain after single appointment retreatment at 1 month
The primary outcome measure of the study was to assess if different nickel titanium root canal shaping systems influence the intensity and duration of postoperative pain in single-visit non-surgical root canal re-treatments. Postoperative pain was recorded using a four-level verbal rating scale, where 0 indicated no pain, 1 indicated slight pain, 2 indicated moderate pain, and 3 indicated sever pain. the patients were asked to return to the clinic for assessing postoperative pain (tenderness to palpation and percussion) at 24, 48, and 72 h; 7 days; and 1 month after the treatment. One clinician performed all the assessments at 24, 48, and 72 h; 7 days; and 1 month.
