About this study
Official title: Comparative Evaluation of Antibacterial Effect of Allium Sativum, Calcium Hydroxide and Their Combination as Intracanal Medicaments in Infected Mature Teeth. A Randomized Control Trial
This study was to evaluate and compare garlic extract antibacterial effect when used as an intra-canal medicament in infected mature anterior teeth with calcium hydroxide and a mixture of calcium hydroxide and garlic, using real time PCR analysis.
Read the detailed description
Sixty-six permanent mature necrotic incisors associated with apical periodontitis in male children were selected. Teeth were randomly divided into three groups (n=22) according to intra canal medications used; group I: Ca OH2, group II: garlic extract and group III: mixture of Ca OH2 and garlic extract. After access preparation, four microbiological samples (S) were taken using sterile absorbent paper points as follows; (S1): were taken before canal instrumentation and irrigation. (S2): after cleaning and shaping, Then, the third samples (S3) and forth samples (S4) were taken after placement of the tested intracanal medications into the corresponding canals, for 7 and 14 days respectively. Total DNA was extracted from microbiological samples and relative quantitive real time PCR reactions were done to quantify the relative gene expression levels (FC) for Streptococcus and Enterococcus faecalis species. Data was statistically analyzed using Kruskal-Wallis and Freidman's tests, followed by Mann-Whitney and Wilcoxon singed rank tests at significance level p ≤ 0.05.

What is being measured
The primary outcome is the main question the study is designed to answer.
Test the antibacterial efficiency of Garlic extract as intracanal medicament in comparison to Calcium hydroxide and their combinations , against E.faecalis and streptococcus bacteria using qRT-PCR analysis.
The change in the mean relative gene expression (bacterial load), for E.faecalis and streptococcus species was measured using quantitative real time polymerase chain reaction (qRT-PCR) after placement garlic (Allium Sativum), Calcium hydroxide and their combinations for one week, in infected single rooted anterior teeth. Statistical analysis was done to compare between the tested medicaments
Measured: 12 months
Secondary outcomes (1)

The change in the mean relative gene expression (bacterial load), for E.faecalis and streptococcus species was measured using quantitative real time polymerase chain reaction (qRT-PCR) after placement garlic (Allium Sativum), Calcium hydroxide and their combinations for two weeks, in infected single rooted anterior teeth. Statistical analysis was done to compare between the tested medicaments.
Measured: 12 months

Questions about this trial
What is this clinical trial studying?
A Phase 2/3 study testing Allium Sativum and Polymerase chain reaction in people with Drug Effect, run by Suez Canal 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 3 inclusion and 5 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 20 Sep 2021. 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 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?
Test the antibacterial efficiency of Garlic extract as intracanal medicament in comparison to Calcium hydroxide and their combinations , against E.faecalis and streptococcus bacteria using qRT-PCR analysis. (time frame: 12 months). 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 20 Sep 2021; AzTrials last refreshed its copy on 8 Nov 2026.
