Comparision of Calcium Hydroxide, Chlorhexidine Gel and Silver Nanoparticles Paste as Intracanal Medicaments in Reducing Post Operative Pain : an Invivo Study

Abstract

Aim: This research seeks to assess the efficacy of calcium hydroxide paste(Ca(OH)₂), chlorhexidine gel(CHX Gel) , and silver nanoparticle paste as intracanal medicaments in minimizing postoperative discomfort.

Materials and Methods: 30 patients presenting with emergency pain were randomly assigned to 3 groups: G I received Ca(OH)₂ paste, GII received CHX gel, and G III received silver nanoparticle paste as intracanal medicaments. Preoperative pain levels were recorded using a visual analog scale (VAS). Postoperative pain was assessed at 6 hours, 48 hours, and 7 days after treatment using the same VAS.

Statistical Analysis Data was statistical analysed using Kruskal-Wallis Test and Friedman Test.

Results: At the 3-day (72-hour) mark, significant differences in pain reduction were observed among the groups. Patients treated with silver nanoparticle paste reported the greatest reduction in pain, followed by those who received calcium hydroxide paste.

Conclusions: Silver nanoparticle paste seems to be the most effective intracanal medicament for alleviating postoperative pain, while calcium hydroxide paste also demonstrates positive effects.
