Effect of Two Different Cryotherapy Irrigation Protocols on Postoperative Endodontic Pain
Sponsor: Cairo University
Summary
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.

Conditions
Interventions
Full Cryotherapy Irrigation (FC)
Full intracanal irrigation performed using 2.5% cold sodium hypochlorite solution (2-3°C) throughout the treatment procedure, followed by cold saline (2-3°C), EDTA, and a final rinse with cold saline
Final Flush Cryotherapy Irrigation (FFC)
Full intracanal irrigation performed using 2.5% sodium hypochlorite solution at room temperature throughout the treatment procedure, followed by saline and EDTA at room temperature, and a final rinse with cryotreated saline (2-3°C).
Conventional Irrigation (CI)
Full intracanal irrigation performed at room-temperature using 2.5% sodium hypochlorite solution, followed by saline, EDTA, and a final rinse with saline.
