An in vitro determination of antibacterial effect of silver nanoparticles gel as an intracanal medicament in combination with other medicaments against Enterococcus fecalis

AIM: The main aim of the study is to compare the antibacterial effect of Silver nanoparticle gel alone and combination of silver nanoparticle gel with various medicaments. MATERIALS AND METHODS: Intracanal dressings: Group 1 –Silver Nanocure gel, Group 2 - Silver Nanocure gel+ Cavisept gel(1:1),Group 3- Silver Nanocure gel+ Aveu-Cal gel(1:1) ,Group 4 – Silver Nanocure gel +Cavisept gel +Aveu-Cal gel(1:1:1) were taken on a culture plate inoculated with E.faecalis. Antibacterial activity was assessed using Agar diffusion test and results were noted as diameter of growth inhibition zone. STATISTICAL ANALYSIS: Student t –test was used to analyse results. RESULTS: The diameter of combination of Silver nanocure gel+Cavisept +Aveu-Cal gel(1:1:1) was highest in comparison to other medicaments tested. CONCLUSION: Intracanal dressing with a combination of all the three {Silver nanocure gel+Cavisept +Aveu-Cal gel(1:1:1) } is the best treatment for elimination of highly resistant Enterococcus faecalis in root canals.
