Effect of Intra-Canal Cryotherapy on Postoperative Pain After Endodontic Procedures
Effect of Intra-Canal Cryotherapy on Post Operative Pain After Primary and Secondary Root Canal Treatment: A Randomized Controlled Trial
The goal of this randomised clinical trial is to evaluate the effect of cryotherapy on postoperative pain after primary and secondary root canal treatment. The main question[s] it aims to answer are:
- Dose cryotherapy help reduce postoperative pain after primary root canal treatment.
- Dose cryotherapy help reduce postoperative pain after secondary root canal treatment.
Participants will be randomly divided to receive either cryotherapy or irrigation with normal saline and the effect between the two groups in terms of postoperative pain will be compared after primary and secondary root canal treatment.

Detailed Description
Procedure
Previous pain assessment:
Both pre- and postoperative pain will be assessed using Huskinsson's visual analog scale (VAS). According to the quantitative data obtained from the VAS scale, these values are categorized as follows: no pain (0), slight pain (0.1-3.9), moderate pain (4-6.9) or pain severe (7-10).
Informed consent After the procedure is carefully explained to the patient and the patient has accepted the treatment plan and signed the Consent, they will be included in the study. Students will give a complete explanation of the study, the forms of pain and how to properly fill out the pain form. If the patient wishes to participate, they will sign the document in order to continue with the treatment and be included in the study.
Root canal treatment and retreatment Vitality test which includes cold test using Endo Ice (Coltene, Switzerland) and Electrical pulp test (EPT) (Shadental, India) for cases of primary root canal treatment. Vertical and lateral percussion tests, periodontal probing, and periapical and bitewing radiographs will be performed in order to perform the pulpal and periapical diagnosis.
The general treatment protocol will be the same for all groups. In case of primary root canal treatment, after the clinical examination, the cold test (Endo-Frost, Coltene-Whaledent, Langenau, Germany) will be used to determine the vitality of the pulp, which will be verified by the presence or absence of bleeding from the root canals during the preparation of the pulp endodontic access.
Local infiltration with 2% lidocaine with epinephrine 1: 80,000 (Ultracain, Normon) will be performed, and absolute isolation with a rubber dam and the department's endodontic protocol will be followed. Access cavity with sterile round diamond drills and Endo-Z drills (Dentsply Maillefer, Ballaigues, Switzerland). The working length (WL) is established with a #10 K-file and apex locator and confirmed with a periapical radiograph. In case of secondary root canal treatment, gutta percha removal and disobturation will be done using different types of rotary and manual files and canals will be negotiated till patency is achieved in all canals, if patency is not achieved the case will be excluded from the study. After which for both primary and secondary root canal treatment instrumentation of the canals will be performed in which they will be irrigated with 1.3% NaOCl solution using a plastic syringe and side-exit needle (Max-i-probe, Kerr-Hawe, Bioggio, Switzerland). Apical patency will be maintained throughout the procedure. Once the procedure is complete, 1 ml of 17% EDTA will be used and a final irrigation with 1.3% NaOCl will be performed with ultrasonic activation using the Irrisafe tip (Acteon, UK).
In the control group, a final irrigation will be performed with 5 ml of 0.9% physiological saline (Sodium Chloride IV infusion 0.9% (Gulf Inject LLC)) at room temperature and in the experimental group with the saline at 2.5ºC for 4 minutes with an endo needle inserted at working length. The saline solution for the control group will be kept at room temperature. The saline solution of the experimental groups will be kept in a refrigerator set at 2.5 C until clinical use.
- Group 1: Conventional root canal treatment with final irrigation with saline at room temperature (n=30).
- Group 2: Conventional root canal retreatment with final irrigation with saline at room temperature (n=30).
- Group 3: Conventional root canal treatment with final irrigation with saline at 2.5ºC for 4 minutes (n=30).
- Group 2: Conventional root canal retreatment with final irrigation with saline at 2.5ºC for 4 minutes (n=30).
The canals will be dried with paper points. The canals of both groups will be filled using a warm gutta-percha filling technique. AH-Plus cement (Dentsply, DeTrey GmbH, Konstanz, Germany) will be used as root canal sealer. Each coronal access will be sealed with a flowable resin (Tetric, IvoclarVivadent AG, SchaanFurstentum, Liechtenstein) and the access cavity will be filled with Glass Ionomer Cement (GIC, ESPE dental, Seefeld, Germany).
Post-operative pain assessment A sheet will be given to the patient with different lines of VAS so that the patient reports the intensity of pain or its absence in the same way that he has been previously taught with preoperative pain at 8, 24 and 48h, 7 days. An ibuprofen 600 mg every 8-12 hours will be recommended for pain control when necessary. The type of analgesic, its quantity and dose will also be recorded in the event that the patients take any type of medication. Patients will be asked to return the VAS collection sheet at the next restoration or general treatment plan continuation visit at the University Clinic. Both the preoperative and postoperative pain results recorded on the Huskinsson VAS scale will be measured by an operator independent of the study, who will be previously calibrated, teaching the evaluator to measure 10 times with a ruler the distance between the initial point of the line to the point marked by the patient on it.
