Intracanal Cryotherapy Reduces Postoperative Pain in Teeth with Symptomatic Apical Periodontitis: A Randomized...

Area of Science:

• Endodontics
• Pain Management
• Cryotherapy

Background:

• Postoperative pain is a common concern for patients with pulp necrosis and symptomatic apical periodontitis.
• Effective pain management strategies are crucial for improving patient outcomes and satisfaction.

Purpose of the Study:

• To evaluate the efficacy of controlled irrigation with cold saline in reducing the incidence and intensity of postoperative pain.
• To compare the effects of cold saline irrigation versus room temperature saline irrigation in endodontic treatment.

Main Methods:

• A randomized clinical trial involving 210 patients with necrotic uniradicular teeth and symptomatic apical periodontitis.
• Patients received final irrigation with either cold (2.5°C) or room temperature saline solution.
• Postoperative pain, intensity, and analgesic intake were recorded and analyzed using statistical tests.

Main Results:

• The group receiving cold saline irrigation (cryotherapy) experienced significantly lower incidence of postoperative pain.
• Patients in the cold saline group required less analgesic medication compared to the control group.
• Pain intensity was also significantly reduced in the experimental group.

Conclusions:

• Controlled irrigation with cold saline (cryotherapy) effectively reduces postoperative pain and the need for analgesics.
• This endodontic pain management technique is beneficial for patients with necrotic pulp and symptomatic apical periodontitis.
• Cold saline irrigation presents a viable and effective adjunctive therapy in endodontic procedures.
