About this study
Official title: Comparative Evaluation of the Effectiveness of Premedication With Two Different Single Doses of Prednisolone on Inter-appointment Pain in Symptomatic Patients With Irreversible Pulpitis: a Double-blind Randomized Controlled Clinical Trial
The purpose of this prospective randomized, double-blind, placebo-controlled study is to compare the efficiency of 2 different single doses of pre-operative oral prednisolone (20 \& 40 mg) for the control of inter-appointment endodontic pain in patients diagnosed with symptomatic irreversible pulpitis. The tested null hypothesis is that there is no difference in pain relief between the two doses.
Seventy-two patients presented for treatment at Dental University Hospital will be selected. The inclusion criteria are systemically healthy patients (ASA classification I or II), with no contraindications to corticosteroids (osteoporosis, systemic fungal infections, poorly controlled insulin-dependent diabetes mellitus, ocular herpes simplex, primary glaucoma, allergy to corticosteroids, ulcerative colitis, a compromised immune status, and major psychosis). Patients under 18 years, pregnant or breast-feeding, took an analgesic agent within the last 6 hours, those with un-restorable teeth, teeth with periodontal disease will be excluded. Patients having mandibular molars with symptomatic irreversible pulpitis with normal periapical area and moderate-severe preoperative pain (i.e. ≥ 34 mm on a visual analog scale (VAS)) will be included.
Subjects will be randomly divided into 3 groups, namely placebo (control), 20 mg prednisolone and 40 mg prednisolone according to a computerized random numbers. Each participant will receive a single oral dose of either formulation (drug or placebo) 30 minutes before starting endodontic treatment. All medications will be placed in identical containers and will be coded; thus, both the operator and the patients will be blinded to the type of medication. Endodontic treatment will be performed and canals will be instrumented to a minimum of size 30, .04 taper following the standardized protocol. Postoperative pain will be assessed by using a visual analogue scale at 4, 12, 24 and 48 hours after initiation of therapy.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Prednisolone and lactose in capsules gelatin in people with Endodontics and Pain, run by King Saud University.
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 1 inclusion and 1 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: status not confirmed, as of the sponsor's last update on 22 Jul 2020. 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?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Results are not available in the source record.
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?
Change in post-operative pain (time frame: Change from baseline pain and pain at 4, 12, 24, and 48 hours after initiation of therapy). 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 22 Jul 2020.
