Ultrasonic Activated Irrigation and Intracanal Cryotherapy for Reducing Pain After Root Canal Treatment
Effect of Using Ultrasonic Activated Irrigation, With and Without Intracanal Cryotherapy, on Post-Operative Pain After Single Visit Root Canal Treatment of Teeth With Symptomatic Irreversible Pulpitis: A Randomized Controlled Trial
This randomized controlled trial aims to evaluate the effect of ultrasonic activated irrigation with and without intracanal cryotherapy on postoperative pain following single-visit root canal treatment in teeth with symptomatic irreversible pulpitis.
Participants requiring root canal treatment will be randomly allocated into two groups. One group will receive ultrasonic activated irrigation alone, while the other group will receive ultrasonic activated irrigation followed by intracanal cryotherapy. Postoperative pain will be assessed at predetermined time intervals using a standardized pain assessment scale.
The findings of this study may help identify effective strategies for reducing postoperative pain after root canal treatment and improving patient comfort and treatment outcomes.

상세 설명
Postoperative pain remains one of the most common complications following root canal treatment and may negatively affect patient comfort and treatment acceptance. Various factors, including preoperative status, instrumentation techniques, and irrigation protocols, influence the incidence and severity of post-endodontic pain.
Ultrasonic activated irrigation (UAI) enhances the effectiveness of irrigants by generating acoustic streaming and cavitation, thereby improving debris removal, smear layer elimination, and disinfectant penetration into the root canal system. Intracanal cryotherapy, which involves the application of cold saline as a final irrigant, has been proposed as a non-pharmacological method to reduce postoperative pain by decreasing tissue temperature and exerting anti-inflammatory effects.
This study is a single-center, parallel two-arm, single-blinded randomized controlled trial conducted at the Department of Operative Dentistry and Endodontics, Sardar Begum Dental College, Peshawar, Pakistan. A total of 60 patients aged 20 to 50 years diagnosed with symptomatic irreversible pulpitis in mandibular first or second molars will be enrolled.
Eligible participants will be randomly allocated into two groups using a computer-generated randomization sequence with allocation concealment through sealed opaque envelopes. Group A (control group) will receive ultrasonic activated irrigation without intracanal cryotherapy, whereas Group B (intervention group) will receive ultrasonic activated irrigation followed by intracanal cryotherapy using 0.9% saline at 1.5-2.5°C for 5 minutes.
All treatments will be performed in a single visit under local anesthesia and rubber dam isolation using standardized clinical protocols. Root canal preparation will be carried out using the ProTaper Universal rotary system. Ultrasonic activation will be performed for one minute per canal. Following obturation and permanent restoration, postoperative pain will be assessed using a 10-point Visual Analogue Scale (VAS).
Pain scores will be recorded at 12, 24, 48, and 72 hours postoperatively through telephone follow-up by a blinded assessor. The primary outcome measure is postoperative pain intensity. Analgesic consumption and adverse events will also be documented.
The findings of this study may provide evidence regarding the effectiveness of intracanal cryotherapy as an adjunct to ultrasonic activated irrigation for reducing postoperative pain following single-visit root canal treatment in teeth with symptomatic irreversible pulpitis.

활성 비교기: Ultrasonic Activated Irrigation Without Intracanal Cryorherapy
Participants assigned to this arm will undergo single-visit root canal treatment under local anesthesia and rubber dam isolation.
Root canal preparation will be performed using the ProTaper Universal rotary system.
Irrigation during instrumentation will be carried out using 5.25% sodium hypochlorite with ultrasonic activation for one minute per canal.
At the final irrigation stage, 10 mL of room-temperature 0.9% saline will be delivered over 5 minutes.
The canals will then be obturated and permanently restored in the same visit.
|
Ultrasonic activation of 5.25% sodium hypochlorite was performed for one minute per canal, 1 mm short of the working length, during single-visit root canal treatment to enhance irrigant penetration and canal debridement.
