Abstract
The aim of the present study was to evaluate and compare the post-operative pain after single visit and multiple visit root canal treatment in asymptomatic necrotic mandibular molars using OneShape rotary instrument after 6, 24, 48 hours and 7 days using modified Visual Analogue Scale (mVAS). Materials and Methods: Forty four patients with asymptomatic non vital mandibular molars were included in this trial. After confirming the diagnosis clinically and radiographically, patients were randomly assigned into two equal groups of 22 patients each. The single visit endodontic treatment assigned to the intervention group, while multiple visit endodontic treatment assigned to the control group. Standard endodontic treatment was performed for both groups using rotary OneShape files for shaping, 2.6% sodium hypochlorite for irrigation and single cone technique with resin sealer for obturation. No intracanal medicament was used in the multiple visits group. Results: Results showed that there was no significant difference in postoperative pain (at 6, 24, 48hours and 7 days) between single visit and 1st visit of multiple visit groups. Moreover, statistical analysis revealed no significant difference between the two groups in the median mVAS scores of postoperative pain intensity at all follow-up periods. But there was a significant difference between single visit and 2nd visit of multiple visits group in postoperative pain at 6h, 24h and 48 hours, and there was no significant difference in postoperative pain after 7 days
