Material& Methods This prospective double-blind, controlled, parallel, superiority, randomized clinical trial was carried out on sixty-six permanent, necrotic incisors associated with asymptomatic apical periodontitis in sixty-six male patients. Patients were randomly divided into three groups (n =22) according to the intra -canal medications used. After access preparation, four microbiological samples (S) were taken using sterile absorbent paper points as follows: S1: before canal instrumentation. S2: after cleaning and shaping. The third samples (S3) and fourth samples (S4) were taken after the placement of the tested intracanal medications into their corresponding canals for 7 and 14 days, respectively. Total DNA was extracted from microbiological samples and relative quantitative real time PCR reactions were done to quantify the relative gene expression fold change (FC) for Enterococcus faecalis and Streptococcus species. At significance level p ≤ 0.05, the data were statist ically analyzed in SPSS software using Kruskal-Wallis and Freidman's tests, followed by Dunn-Bonferroni post-hoc test for pairwise comparisons. Results Both bacterial mean FC decreased significantly after mechanical instrumentation (S1 to S2) in all groups. However, no statistically significant differences were found after intra-canal medicament placement (from S2 to S3 and from S3 to S4) except in the garlic group. Garlic significantly reduced Enterococcus faecalis FC in S3 and S4 when compared to Ca (OH) 2 and Ca (OH) 2+ garlic combination. However, garlic and Ca (OH)2 reduced Streptococcus bacteria in S3 similarly. While in S4, garlic showed significantly more reduction than Ca (OH) 2. The combination of Ca (OH) 2 with garlic extract showed the least significant bacterial reduction. Conclusion within the study limitations, garlic intra-canal medicament has a comparable anti-Streptococcus efficiency to Ca (OH) 2, while it is more effective against Enterococcus faecalis species. When Ca (OH)2 and garlic are combined, their antibacterial effectiveness is reduced. Increasing the time of application for tested intracanal medicaments by more than one week has no additional antibacterial effectiveness. View on Web
