Abstract

Aim: This research aimed to assess the effect of 20% ascorbic acid final flush on post operative pain intensity in mandibular molars with symptomatic irreversible pulpitis after single visit root canal treatment.
Subjects and methods: Thirty patients were randomly divided into two groups (n = 15), saline (group A) and ascorbic acid (group B). After completion of mechanical preparation using Mpro rotary system in a single visit and using sodium hypochlorite 2.5% as an irrigant, group A received 3ml of saline as a final flush for each canal for 1 minute. Group B received also the same saline flush of group A then 3ml of 20% ascorbic acid as a final flush for each canal. Dryness of the canals and obturation were done with gutta-percha 0.04 by lateral compaction technique. postoperative pain was recorded immediately after obturation and at 6- 12- 24 and 48 hours postoperatively on numerical rating scale chart (NRS) and analgesics consumption up to 48 hours postoperatively. NRS scores were collected and statistically analysed by unpaired student t-test and Mann-Whitney test (p> 0.05).
Results: For pain incidence, intensity and analgesics consumption there was no statistically significant difference could be demonstrated regarding the numerical rating scale score between the two groups at any time points (p> 0.05).
Conclusion: Within the study limitations, using 20% ascorbic acid as a final flush irrigation did not significantly affect neither the post root canal treatment pain nor the consumption of analgesics in mandibular molars with symptomatic irreversible pulpitis.
