Özet

As one of the global concerns, antimicrobial resistance crisis increases the clinical importance of Enterococcus species. Enterococcus faecalis (E. faecalis) specifically penetrates the dentinal tubules and remains prevalent even after endodontic treatment. It has also biofilm forming character as well as the development of resistance to antibiotics. Sodium hypochlorite (NaOCl) is considered the gold standard among antibacterial washing solutions. However, due to its toxic effects, its usage limitations have led to the search for natural, non-toxic alternatives. Phages can be considered an important alternative because of their effects on specific bacteria. The objective of this study was to compare the effect of isolated active vB_Ef1 phage on the removal of E. faecalis biofilm in dentin, together and separately with the chemical irrigation solution NaOCl. As a result of study, the optimal NaOCl solution concentration to be applied with vB_Ef1 phage is 0.5 %, and the use of solution at this value reduces the biofilm mass by 84 %, reaching the highest biofilm mass reduction value. It was found that the combination of phage and NaOCl at appropriate concentrations had the strongest biofilm disruption effect.
