Purpose With the demand for better efficiency during endodontic therapy, the purpose of this in vitro study was to evaluate the efficiency of ethyl acetate (EthOAc) extract of Matricaria chamomilla (L.) against Enterococcus faecalis and compare with standard root canal irrigation solutions. Material and Methods The antibacterial effect against Enterococcus faecalis of the EthOAc extract of Matricaria chamomilla was assessed without, or with dentine powder, using agar disk diffusion method. The inhibition zones induced by the EthOAc extract were observed after 5 minutes, 60 minutes, and 24 hours and compared with standard irrigation solutions (2% chlorhexidine and 2% sodium hypochlorite) without, or after mixing with dentine powder. Statistical analysis of the results were analysed with the Kruskal–Wallis test and one-way ANOVA. Results There was no inhibition zone in samples with and without dentine powder after combination of ethyl acetate extract of Matricaria chamomilla with sodium hypochlorite. When the extract was used alone in samples without dentine powder, the inhibition zone was 9.7 mm after 24 h, but this zone was decreased after adding dentine powder (7.7 mm). When the extract was used in combination with CHX, the inhibition zone in samples with dentine powder was 25.3 mm, but it was decreased after adding dentine powder (21.7 mm). Conclusion The EthOAc extract of Matricaria chamomilla as alternative root canal irrigant may be a useful natural agent with antibacterial activity against Enterococcus faecalis . Also, it showed promising results in endodontic therapy after combination with chlorhexidine in Enterococcus faecalis eradication.

“…Successful endodontic treatment depends on three crucial elements: instrumentation, disinfection and obturation. In pediatric endodontics, the primary aim is to preserve deciduous teeth and aid in the emergence of permanent successors (Munaga et al, 2022). To achieve optimal results, irrigation is essential to access the intricate anatomy of root canals and remove tissues that can't be reached with mechanical cleaning (Neha et al, 2014).…”

Article HistoryBackground: In endodontic therapy, root canal irrigants are utilized to enhance mechanical debridement. However, conventional irrigants have certain drawbacks, such as being incapable of removing the smear layer, causing tissue irritation, toxicity, and unpleasant taste, especially in children. Therefore, there is a growing necessity to explore natural alternatives, such as herbal irrigants. This study sought to evaluate the antimicrobial effectiveness of German chamomile, tea tree oil (TTO), and chlorhexidine (CHX) as root canal irrigants against E. faecalis and Streptococcus mutans. Method: Fifteen test samples of German chamomile extract, tea tree oil, and chlorhexidine were taken. Indicator strains were grown in Brain Heart Infusion (BHI) agar at 37ºC for 24 hr. In preparation for the experiment, a 15 ml base layer of BHI agar was mixed with 300µl of each inoculum and placed in individual sterilized petri plates. Once the culture medium had solidified, four wells were created on each plate and subsequently filled with the designated testing materials. This methodology was employed to ensure methodological rigor and accuracy in the experimental process. In preparation for the experiment, a 15 ml base layer of BHI agar was mixed with 300µl of each inoculum and placed in individual sterilized petri plates. Once the culture medium had solidified, four wells were created on each plate and subsequently filled with the designated testing materials. This methodology was employed to ensure methodological rigor and accuracy in the experimental process. The plates were kept for 2 hours at room temperature for the diffusion of the material and then incubated at 37ºC for 48 hours. Antibacterial tests were repeated 5 times for homogeneity of the results. Results: The comparison of antimicrobial efficacy of chlorhexidine 2%, tea tree oil, and German chamomile showed a significant difference whereas the comparison between chlorhexidine 2% and tea tree oil was statistically insignificant. Conclusion: The effective reduction in the microbial count by all three test irrigants was observed to be significant. The antimicrobial efficacy of tea tree oil was found to be better than 2% chlorhexidine and German chamomile extract.
