About this study

Official title: Clinical Evaluation of Direct Pulp Capping in Primary Molars

Read the detailed description

After informed consent, baseline clinical and radiographic assessment will be obtained and recorded in patient examination sheet.

Participants who met the inclusion criteria were randomly allocated to two groups (n = 26/group, N = 52 in total) according to the capping martials using the envelope randomization method.

2 study groups according to capping material that will be used (Dycal or MTA) and each group will be divided to 2 subgroups according to site of exposure axial or pulpal.

All patients were recalled and their treated molars were evaluated clinically and radiographically at 3months, 6months, 9months ,12months follow up periods.

Conditions: Direct Pulp Capping
Being tested: Mineral trioxide aggregate (MTA), Hard setting Calcium Hydroxide (Dycal)

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Mineral trioxide aggregate (MTA) and Hard setting Calcium Hydroxide (Dycal) in people with Direct Pulp Capping, run by Mansoura 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 4 inclusion and 3 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 26 Sep 2023. 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. 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 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?

clinical success of direct pulp capping treatment after 3 months follow up (time frame: 3 months). The study lists 8 primary outcomes in all. 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 NCT05530954, which also lists 3 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 26 Sep 2023; AzTrials last refreshed its copy on 27 Oct 2026.
