NCT07434141

Brief Summary

The goal of this clinical trial is to compare post-treatment pain after root canal therapy in adults with irreversible pulpitis using different root canal sealers. The study will also evaluate the need for pain medication after treatment. The main questions this study aims to answer are: Does the type of root canal sealer affect the intensity of pain after treatment? Does the type of sealer influence the number of analgesic tablets taken by participants? How does pain change over time after treatment with different sealers? Researchers will compare two bioceramic sealers (EndoSeal TCS and NeoSeal) with a resin-based sealer (AH Plus) to determine their effects on post-endodontic pain. Participants will: Receive root canal treatment using one of the study sealers Report their pain intensity at specific time points after treatment Record the number of analgesic tablets taken during the follow-up period

Outcome Measures

Primary Outcomes (1)

  • Post-Endodontic Pain Intensity

    Pain intensity experienced by participants after root canal treatment will be measured using a Visual Analog Scale (VAS; 0-10 numeric rating scale), where: 0 = no pain 10 = worst imaginable pain Higher scores indicate greater pain intensity (worse outcome). Participants will also record the number of analgesic tablets consumed during the first 48 hours after treatment. The maximum VAS pain score recorded during the first 48 hours will be considered the primary outcome

    Pain will be assessed at 6, 12,18, 24, and 48 hours post-treatment

Secondary Outcomes (1)

  • Analgesic Consumption

    Within 48 hours post-treatment

Study Arms (3)

EndoSeal TCS

EXPERIMENTAL

Participants receive single-visit root canal treatment using the bioceramic sealer EndoSeal TCS with the single-cone obturation technique. Postoperative pain intensity and analgesic consumption are recorded at predefined time intervals

Procedure: Endoseal TCS

NeoSealer

EXPERIMENTAL

Participants receive single-visit root canal treatment using the bioceramic sealer NeoSealer with the single-cone obturation technique. Postoperative pain intensity and analgesic consumption are recorded at predefined time intervals.

Procedure: Neosealer

AH Plus

EXPERIMENTAL

Participants receive single-visit root canal treatment using the resin-based sealer AH Plus with the single-cone obturation technique. Postoperative pain intensity and analgesic consumption are recorded at predefined time intervals

Procedure: AH Plus
