Brief summary
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.
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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| 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. | 12 months | 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 |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Test the antibacterial effect of increasing the contact time (14 days) for garlic (Allium Sativum), Calcium hydroxide or their combinations inside infected root canals, against E.faecalis and streptococcus bacteria using qRT-PCR analysis. | 12 months | 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.
