ABSTRACT

Introduction: An important aspect in endodontic practice is controlling pain during and after root canal treatment; to control the postoperative pain several strategies have been developed including the use of analgesics long-standing anaesthesia and different techniques in root canal preparation. This study was conducted to evaluate and compare the effect of intracanal cryotherapy in reducing postoperative pain in patients with irreversible pulpitis with and without apical periodontitis.
Method: A randomized control trial had been conducted among 40 patients with irreversible pulpitis. The patients were randomly divided according to the temperature of the final irrigant used, into two groups control (1) using saline at room temperature, and study group (2) using cold saline. Then further subdivided into two subgroups according to pulpal diagnosis, either irreversible pulpitis with apical periodontitis (subgroup a) or irreversible pulpitis without apical periodontitis (subgroup b). Visual analogue scale (VAS) was used to evaluate and compare postoperative pain.
Results: A statistically significant difference was found when comparing the pain level in cryotherapy group (subgroup 2a) with control group (subgroup 1a) 24, 48 hours postoperatively. But there was no statistically significant difference when comparing the pain level in cryotherapy (subgroup 1b) with control (subgroup 1b) after 24, 48 hours postoperatively (p>0.05).
Conclusion: Using intracanal cryotherapy is effective in reducing postoperative pain in patients with irreversible pulpitis with apical periodontitis. But it does not affect patients with irreversible pulpitis without apical periodontitis

Key words: Intracanal cryotherapy, postoperative pain, Irreversible pulpitis.
