About this study
This randomized, parallel-group clinical trial aimed to compare the effects of two root canal sealers, AH Plus and Well-Root ST, on postoperative pain in patients undergoing single-visit root canal treatment for teeth diagnosed with apical periodontitis.
A total of 120 patients were allocated to two treatment groups (n = 60 per group) using a sealed-envelope allocation method. Participants were unaware of which root canal sealer was used during their treatment.
Postoperative pain was assessed using a visual analog scale (VAS) at 24, 48, and 72 hours, 1 week, and 1 month after treatment.
Read the detailed description
This single-center, randomized, parallel-group clinical trial included 120 patients diagnosed with apical periodontitis who underwent single-visit root canal treatment.
Participants were allocated to two treatment groups using a sealed-envelope method. A total of 120 identical, opaque, sealed envelopes were prepared, with 60 assignments for the AH Plus group and 60 assignments for the Well-Root ST group. The envelopes were manually shuffled before patient enrollment. Each participant selected an envelope immediately before treatment, and the assigned root canal sealer was used.
Group 1 consisted of 60 patients treated with AH Plus root canal sealer, while Group 2 consisted of 60 patients treated with Well-Root ST root canal sealer. Participants were unaware of which sealer was used during treatment, whereas the treating operator was not blinded.
Data collected included age, sex, clinical examination findings, tooth type and number, duration of root canal treatment, and preoperative and postoperative pain scores.
Pain intensity was assessed using a visual analog scale (VAS) before treatment and at 24 hours, 48 hours, 72 hours, 1 week, and 1 month after treatment.
The primary objective was to compare postoperative pain intensity between the two root canal sealer groups.

What is being measured
The primary outcome is the main question the study is designed to answer.
Postoperative Pain Intensity Measured Using a Visual Analog Scale (VAS)
Postoperative pain intensity was assessed using a 10-cm visual analog scale (VAS). Participants recorded their pain intensity before treatment (baseline) and at specified postoperative time points. VAS scores were compared between the AH Plus and Well-Root ST groups.
Measured: Baseline (preoperative), and 24 hours, 48 hours, 72 hours, 7 days, and 1 month postoperatively.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Nov 2026; AzTrials last refreshed its copy on 7 Nov 2026.
