简要总结
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.

研究组 & 干预措施
Conventional Calcium Hydroxide (CH)
Following completion of canal shaping with rotary instrumentation and irrigation using 5 mL of 2.5% sodium hypochlorite (NaOCl), canals were flushed sequentially with 5 mL distilled water, 5 mL of 17% ethylenediaminetetraacetic acid (EDTA), another 5 mL of distilled water, 5 mL of 2.5% NaOCl, and finally 5 mL of distilled water. Canals were then dried using sterile paper points. Conventional calcium hydroxide (CH) paste was introduced into the canal using a Lentulo spiral. A sterile cotton pellet was placed in the pulp chamber, and the cavity was sealed with glass ionomer cement.

Nanocalcium Hydroxide (NCH)
Following completion of canal shaping with rotary instrumentation and irrigation using 5 mL of 2.5% sodium hypochlorite (NaOCl), canals were flushed sequentially with 5 mL distilled water, 5 mL of 17% ethylenediaminetetraacetic acid (EDTA), another 5 mL of distilled water, 5 mL of 2.5% NaOCl, and finally 5 mL of distilled water. Canals were then dried using sterile paper points. Nanocalcium hydroxide (NCH) paste was placed into the canal using a Lentulo spiral to ensure uniform distribution. The access cavity was temporarily restored with a sterile cotton pellet and glass ionomer cement.

结局指标
主要结局
Visual Analogue Scale (VAS)
时间窗: up to 72 hours
The visual analog scale for pain is a straight line with one end meaning no pain (0) and the other end meaning the worst pain (10) imaginable. A patient marks a point on the line that matches the amount of pain he or she feels. It may be used to help choose the right dose of pain medicine. Also called VAS.
