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

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. The cavity was sealed temporarily with a sterile cotton pellet and glass ionomer cement. Conventional calcium hydroxide was retained for 7 days before final obturation.
