The purpose of this study was to evaluate the antibacterial efficacy of silver Nanoparticles, Nanoparticle calcium hydroxide and calcium hydroxide as intracanal medicament against Enterococcus faecalis bio film formed on root dentinThe Minimal inhibitory concentration test and Anti microbial test were conducted for silver nanoparticle, Nanoparticle calcium hydroxide. Teeth were inoculated with E.faecalis strains for 1month to establish a standard mono species bio film model. Biofilm formation is confirmed using SEM. The intracanal medicaments were placed inside the canal and colony forming units (CFU) were counted before and 7 days later the placement of the medicament.MIC for AGNP is 25µg/200µl and for NCH is 12.5µg/200µl. The Antimicrobial test conducted shows zone of inhibition about 11mm and 14mm for AGNP and NCH respectively at 500µg. The calcium hydroxides do not show any antibacterial activity at this concentration. In antibacterial efficacy test using CFU count, the AGNP and NCH shows 75% and 61% of antibacterial efficacy respectively whereas calcium hydroxide has exhibited just 11% of antibacterial efficacy. Silver Nanoparticles and nanoparticle calcium hydroxide had statistically significant difference in the reduction in the number of colonies when compared to calcium hydroxide by post hoc turkey test and p-value of <0.01 was considered as significant in this study.

Propolis is proposed to possess antibacterial and anti-inflammatory properties, which can be used in endodontic applications. However, evidence on its efficacy in comparison to chlorhexidine against Enterococcus faecalis (E. faecalis) is controversial. The aim of the current study was to compare the antibacterial efficacy of Propolis and chlorhexidine as an intracanal medicament against E. faecalis in extracted human permanent teeth. The focused question was, “Does Propolis show better antibacterial efficacy than Chlorhexidine (CHX) as an intracanal medicament against E. faecalis in extracted human permanent teeth?”. Databases including PubMed/Medline, Scopus, EMBASE, ISI-Web of Science were searched from 1990 to August 2020 using different combinations of the following keywords: “Propolis”, “Intracanal medicament”, “E. faecalis”, “Antibacterial activity” and “Chlorhexidine”. Ten studies fulfilling inclusion criteria were considered for qualitative analysis, followed by quantitative analysis of eight studies. Heterogeneity was calculated for colony forming units (CFU) of E. Faecalis using the Chi-square test and I2 statistics. Forest plots were computed reporting standard mean difference (SMD) of outcomes and 95% confidence intervals. The overall mean difference for CFU of E. faecalis showed a statistically significant difference between the antibacterial efficacy of Propolis and CHX (SMD = 3.20 [1.70, 4.69] Z = 4.20; p < 0.001). CHX showed superior antibacterial efficacy against E. faecalis compared to Propolis.

This study investigates the antibacterial effects of erbium chromium laser at 2780 nm, silver nanoparticles, and erbium chromium along with silver nanoparticles on Enterococcus faecalis in comparison with sodium hypochlorite. In the present study, 90 extracted human single-rooted teeth were selected and standardized to a length of 15 mm. The canals were prepared by V-taper Gold rotary files and then incubated with E. faecalis for 21 days. The samples were divided into four experimental groups including hypochlorite sodium, silver nanoparticle, erbium chromium laser, and erbium chromium laser along with silver nanoparticle groups. Results showed that there was a significant reduction in colony count for all groups after interventions. Moreover, there was a significant reduction in the colony count for sodium hypochlorite group in comparison with another groups, and this group showed the highest reduction of colony count. There was a significant difference between silver nanoparticles and erbium chromium laser groups in colony count. According to the results, the silver nanoparticles offered strong antibacterial effects on E. faecalis and therefore can decrease bacterial colonies, while the use of the laser, despite the reduction of the bacterial colony, could not be sufficiently used for disinfection of root canal system.
