Aim: The aim of present study was to evaluate the effectiveness of cold saline irrigation as final irrigant on postoperative pain after single visit root canal treatment of teeth with vital pulp. Material and method: In present study 30 patients with single rooted tooth were included in the present study. The teeth were randomly divided into two groups. In the cold saline group, final irrigation was performed with 2.5°C saline solution for 5 min after completion of biomechanical preparation; whereas, in the control group (normal saline) same solution stored at the root temperature was used. Single visit treatment was performed in the present study. Participants were asked to rate the intensity of their postoperative pain using visual analogue scale after 24 hrs.
Result: Result showed that the cold saline group resulted in significantly less pain (p < 0.05) in comparison with compared to control group. Conclusion: : The result shows that cold saline irrigation can be used as an effective means to reduce the post operative pain after single visit root canal treatment of teeth with vital pulp.
