简要总结

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.

结局指标

主要结局

Incidence and severity of postoperative pain

时间窗: 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

次要结局

  • Incidence and Number of analgesic intake(From enrollment to the end of treatment at 3 days)
