Aim: The aim of the present study was to evaluate the effect of cryotherapy using cold saline irrigation as a final irrigant on postoperative pain in molar teeth with symptomatic irreversible pulpitis and apical periodontitis
Methods: A total of 30 patients with symptomatic irreversible pulpitis and apical periodontitis in their mandibular first molars, were included in the study. After completion of biomechanical preparation using Mpro Rotary system in a single visit and irrigation with 2.5% sodium hypochlorite for cleaning and shaping. Patients were randomly assigned into two groups (n = 15). In( group A), final irrigation was done using 15 ml cold saline (2.5°C) for 6 mins at three successive times. The solution was stored in refrigerator until use and then its temperature was checked using digital thermometer. In( group B), final irrigation was done using 15 ml room temperature saline for 6 mins. In both groups irrigation procedures were done using 27-gauge side-vented needle fit to a 5ml disposable plastic syringe placed 2-3 mm away from apex without binding. Pain was recorded postoperatively after 6, 12, 24, 48 and 72 hours by Numerical Rating Scale (NRS). Patients were given an analgesic (Ibuprofen 200 mg) in case of severe pain. All demographic data. NRS scores and number of analgesics taken were collected from the patients and statistically analyzed by chi-square test and Mann-whitney U test.
Results: Results showed a statistically significant decrease in postoperative pain in the cryotherapy group compared to the control group at each time interval, also cryotherapy reduced postoperative analgesic intake at all tested intervals (p < 0.05).
Conclusions: Cryotherapy aids in reducing postoperative pain in both magnitude and time span, also it had satisfactory effect on reduction of post-operative analgesic intake. The use of cryotherapy is a simple, cost-effective, and non-toxic option for postoperative pain control in single visit root canal treatment.
