Evaluation of Post-Operative Pain Following the Use of Nano-Calcium Hydroxide

Summary

The goal of this clinical trial is to evaluate the effect of different intracanal medicaments-conventional calcium hydroxide (CH) and nano-sized calcium hydroxide (NCH)-on the intensity of postoperative pain following root canal treatment in asymptomatic necrotic single-rooted teeth. The primary research question of this study is as follows: Does the use of nano-sized calcium hydroxide, compared to conventional calcium hydroxide, result in significantly reduced postoperative pain after root canal treatment? In both groups, standardized instrumentation will be performed using rotary NiTi files and 2.5% sodium hypochlorite irrigation. After cleaning and shaping, canals will be medicated with either CH or NCH, followed by temporary sealing.
