About this study
Official title: Effect of Preoperative, Single-dose Diclofenac Potassium on Postoperative Endodontic Pain in Patients With Symptomatic Irreversible Pulpitis: A Double Blind Randomized Controlled Trial
The purpose of this study is to assess the effect of preoperative a single-dose of 50 mg diclofenac potassium on postoperative endodontic pain in mandibular molars with symptomatic irreversible pulpitis.
Read the detailed description
Patients with moderate-to-severe preoperative pain are selected. Patients receive either a single-dose of 50 mg diclofenac potassium (group A) or a placebo tablet as a control (group B). All patients receive the assigned premedication one hour before single-visit root canal treatment. Postoperative endodontic pain is measured at the following time points: 6 , 12,24,48 h after treatment. The incidence of analgesic intake is also recorded.

Questions about this trial
What is this clinical trial studying?
A Phase 2/3 study testing Diclofenac Potassium 50mg Tab. in people with Pulpitis - Irreversible, run by Cairo University at 1 site in Egypt.
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 5 inclusion and 7 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: finished, as of the sponsor's last update on 9 Apr 2018. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Egypt. Whether a site is taking part right now should be confirmed with that site. See every site.
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 combined phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Postoperative endodontic pain (time frame: Up to 2 days after endodontic treatment). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03341260, which also lists 2 linked publications.
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 9 Apr 2018.
