An interventional study of Video-Guided Breathing Exercise in Symptomatic Irreversible Pulpitis and Postoperative Pain, sponsored by Cukurova University. Completed at 1 site in Turkey (Türkiye). Open to participants aged 18 Years to 65 Years. Per ClinicalTrials.gov, last updated 2026-10-05.
Sponsored by Cukurova University · Not applicable, Interventional, and Treatment
The goal of this randomized controlled clinical trial is to evaluate whether a brief preoperative video-guided breathing exercise reduces postoperative pain in adults undergoing single-visit root canal treatment for symptomatic irreversible pulpitis.
The main questions it aims to answer are:
Participants will be randomly assigned to one of two groups before root canal treatment.
In the video-guided breathing exercise group, participants will watch a standardized 2-minute video and follow a controlled breathing pattern consisting of inhaling through the nose for 4 seconds followed by exhaling for 6 seconds. This breathing cycle will be repeated throughout the video.
In the passive rest group, participants will remain seated in the dental chair for 2 minutes without receiving any breathing or relaxation instructions and will be asked to breathe normally.
All participants will then receive single-visit root canal treatment using the same standardized endodontic treatment protocol.
Postoperative pain will be assessed at 6, 12, 24, 48, and 72 hours after treatment. Pain at 24 hours will be the primary outcome. Maximum pain experienced during treatment, supplemental anesthesia requirement, analgesic use during the first 72 hours, and change in heart rate immediately before and after the assigned preoperative intervention will also be evaluated.
5,093 studies on the registry are indexed under Pain, Postoperative; 1,140 are open to participants now.
This study's enrollment of 90 is above the median of 75 across 4,344 interventional studies indexed under Pain, Postoperative.

Exclusion Criteria:
Participants will perform a standardized 2-minute video-guided breathing exercise before root canal treatment. They will be instructed to inhale through the nose for 4 seconds and then exhale for 6 seconds, repeating this breathing cycle throughout the video.
Behavioral: Video-Guided Breathing Exercise
Participants will remain seated in the dental chair for 2 minutes before root canal treatment without receiving any breathing or relaxation instructions. They will be asked to continue breathing naturally during this period.
Participants assigned to the intervention group will perform a standardized 2-minute video-guided breathing exercise immediately before root canal treatment. During the exercise, participants will be instructed to inhale through the nose for 4 seconds and then exhale for 6 seconds. This breathing cycle will be repeated throughout the 2-minute video. The same video will be used for all participants to standardize the instructions and duration of the intervention.
Postoperative Pain at 24 Hours
Postoperative pain intensity will be assessed 24 hours after single-visit root canal treatment using a 10-cm visual analog scale (VAS), with 0 representing "no pain" and 10 representing "the worst imaginable pain."
Time frame: 24 hours after root canal treatment
