Submucosal Cryotherapy and Anti-inflammatory Drugs for Postoperative Pain Following Root Canal Treatment in Maxillary Molars

• Status: NOT_YET_RECRUITING
• Trial end date: 2027-11-15

Summary

Pain after root canal treatment is a common problem, particularly in teeth with symptomatic irreversible pulpitis, a condition involving severe inflammation of the tissue inside the tooth. Submucosal cryotherapy, which involves applying cold saline through an injection near the affected tooth, may help reduce postoperative pain and inflammation. Anti-inflammatory medications, such as diclofenac sodium and dexamethasone, may also provide pain relief.

This randomized clinical trial aims to evaluate the effects of submucosal cryotherapy, alone or combined with anti-inflammatory medications, on postoperative pain and interleukin-6 (IL-6) levels in patients undergoing root canal treatment of upper molars with symptomatic irreversible pulpitis.

A total of 90 adult patients will be randomly assigned to six groups: local anesthesia alone, cryotherapy with anesthesia, diclofenac sodium with anesthesia, dexamethasone with anesthesia, cryotherapy combined with diclofenac sodium, or cryotherapy combined with dexamethasone. All participants will undergo standardized single-visit root canal treatment.

Postoperative pain will be evaluated during the first 72 hours after treatment. IL-6, a substance involved in inflammation, will be measured in blood samples collected from the dental pulp during treatment. The need for additional pain medication and the occurrence of postoperative flare-ups will also be assessed.

The study seeks to determine whether combining submucosal cryotherapy with anti-inflammatory medications provides greater postoperative pain relief than individual interventions or standard care alone.
