چکیده مقاله:

Background and Aim: Because of complexity in root canals, irrigating solutions are needed in addition to mechanical instrumentation for thorough cleansing of the root canal system. This in-vitro study was designed to determine the inhibitory effect of arginine, protamine, and aqueous extracts of green tea and aloe vera against Enterococcus faecalis (E. faecalis), which causes endodontic failure. Materials and Methods: In this experimental study, aqueous extracts of green tea and aloe vera and protamine at a concentration of 400 mg/ml and arginine at a concentra-tion of 160 mg/ml were used. E. faecalis was cultured on Mueller-Hinton broth, and minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of the test materials against these microorganisms were determined using serial dilutions and according to the microdilution test. The positive control was 2.5% sodium hypochlorite (NaOCl). Results: Aqueous extract of aloe vera has high antibacterial activity against E. faecalis (MIC=12.5 mg/ml and MBC=100 mg/ml), and protamine had the least effect (MIC=400 mg/ml and MBC>400 mg/ml) compared to other test materials. NaOCl, with MIC and MBC of 0.25 mg/ml against E. faecalis, showed higher antibacterial activity compared to other test materials. Conclusion: Among the tested materials, except for NaOCl as a positive control, aqueous extract of aloe vera showed better antibacterial properties against E. faecalis.

A Comparison between Anti-bacterial Activity of Propolis and Aloe vera on Enterococcus faecalis (an In Vitro Study)

Removing the bacteria, including Enterococcus faecalis, from the root canal is one of the important aims in endodontic treatment.We aimed to compare the antibacterial activity of Chlorhexidine with two natural drugs. The antibacterial activities of three different propolis extracts (alcohol concentrations: 0, 15, 40%) and Aloe vera gel on E. faecalis were compared using three methods: disk dif...
