Effect of Two Different Cryotherapy Irrigation Protocols on Postoperative Endodontic Pain (NAOCL/EDTA)
24. juni 2026 opdateret af: Ahmed Mahmoud Mohamed, Cairo University
Effect of Two Intracanal Cryotherapy Irrigation Protocols on Postoperative Endodontic Pain in Patients With Symptomatic Irreversible Pulpitis and Apical Periodontitis in Mandibular Molars: A Randomized Clinical Trial.
The aim of this study is to evaluate the effect of intracanal cryotreated (2-3°C) 2.5% sodium hypochlorite and Saline used throughout the procedure, compared with a room-temperature irrigation protocol with a final cryotreated saline flush or an entirely room temperature irrigation protocol, on postoperative pain in patients with symptomatic irreversible pulpitis and symptomatic apical periodontitis in mandibular molars.

Incidence and severity of postoperative pain
Tidsramme: From enrollment to the end of treatment at 3 days

Using an 11-point Numeric Rating Scale (NRS) where the endpoints are the extremes of no pain and worst pain.
Pain intensity was assigned into one of four pain categories: none (0); Mild (1-3); Moderate (4-6) and severe (7-10).
Postoperative pain levels will be documented by the patients at 6, 12, 24, 48 and 72 hours postoperatively

In case of severe or persistent postoperative pain, the operator will permit the patient to take Ibuprofen (200 mg) not more than 6 hours apart.
Patients will be instructed to record their analgesic consumption by counting the number of tablets taken in the course of 72 hours postoperatively.
