About this study
Official title: Effect of Intentional Extrusion of an Intracanal Corticosteroid Solution on Post Endodontic Treatment Pain: a Randomized Clinical Trial
The aim of this research is to assess the effect of intentionally extruding a corticosteroid intracanal solution into the periapical tissues on the postoperative pain after root canal treatment in patients with symptomatic irreversible pulpitis and symptomatic apical periodontitis (SIP/SAP). The main question it aims to answer: Is there an analgesic effect of extruding an intracanal solution of DXA into the periapical tissues in patients diagnosed with SIP/SAP? Researchers will compare dexamethasone to a placebo to see if the extrusion dexamethasone works in reducing post-endodontic treatment pain.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
DexamethasoneDrug
a 2 ml solution of dexamethasone (3.3mg/ml) will be flushed in the root canal and intentionally extruded to the periradicular tissues to assess its potnetial sedative effect
PlaceboOther
2ml of normal saline will be used as placebo to be flushed and extruded through the canals to the periradicular tissues
| Study group | Role | What they receive |
|---|---|---|
| DXM | Experimental | Patients in this group will receive a standard root canal treatment but with the extra step of extruding a Dexamethasone (DXM) solution through the root canals to the periradicular tissues prior to obturation. Receives: Drug: Dexamethasone |
| Saline | Placebo comparator | Patients in this group will receive a standard root canal treatment with saline used as the final irrigating solution prior to obturation. Receives: Other: Placebo |
What is being measured
The primary outcome is the main question the study is designed to answer.
Post-operative pain following root canal treatment
The outcome measure is patient-reported pain following root canal treatment. Patients will be given a questionnaire to complete, on 4 different time intervals following the completion of their root canal treatment (12, 24, 48 and 72 h). For each time interval, patients will be asked to fill out:
- their perceived pain level on a standard 100mm visual-analogue scale, with pain values ranging from zero (no pain at all) and ascending gradually until 100 (worst imagined pain).
- Whether they needed to take any analgesics. In this case, details about the type, route, dose and timing of the analgesic taken will have to be filled out
Measured: at 12, 24, 48 and 72 hours after completing the treatment

Questions about this trial
What is this clinical trial studying?
A Early Phase 1 study testing Dexamethasone in people with Post Operative Pain Control and Endodontic Treatment, run by University of Jordan.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: opening soon, as of the sponsor's last update on 26 Mar 2025. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Renad H Khanfer (+962795101571, renad_hazem@hotmai.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Post-operative pain following root canal treatment (time frame: at 12, 24, 48 and 72 hours after completing the treatment). It is what the study was designed to measure, not a finding.
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 26 Mar 2025; AzTrials last refreshed its copy on 7 Nov 2026.
