Removing infectious bacteria biofilms from the root canal system is crucial for a successful endodontic treatment. This study investigated antibacterial effect of femtosecond laser (fs-laser) against Enterococcus faecalis (E. faecalis) and Fusobacterium nucleatum (F. nucleatum) on dentin. The chemical composition dentin slices extracted human teeth was analyzed using FTIR Raman probes. morphology fs-laser ablated grooves evaluated by an optical profiler, ablation fluence threshold obtained...
Root canal irrigants are difficult to diffuse deep into the dentinal tubules for root disinfection. The purpose of this study was assess ability different diffusing enhancers deliver chlorhexidine (CHX) tubules. property five (acetone, DMSO, Triton X-100, JFC-E and azone) firstly assessed using Rhodamine B. CHX then evaluated both qualitatively quantitatively. A tubule Enterococcus faecalis infection model further established test bactericidal effect delivered by enhancers. Finally, in vitro...
