Multifunctional scaffolds with host defense peptides designed for regenerative endodontics are desirable nanobiotechnological tools for ***,different scaffolds were tested for use during the pulp revascularization process,including poly(vinyl alcohol)-PVA hydrogels or resins,collagen hydrogels and poly(vinyl alcohol)PVA/Chitosan(PVA/CS)*** on time to degradation(21 days),nanofibers were chosen to be incorporated with ciprofloxacin and IDR-1002(each at 50 mg/g).Nanofibers containing ciprofloxacin and IDR-1002 had anti-biofilm activity against Enterococcus faecalis,Staphylococcus aureus and a multispecies oral biofilm,besides anti-inflammatory *** in vivo subcutaneous tissue response to tooth fragments filled with nanofibers demonstrated a pulp-like tissue formation,when compared to empty teeth ***,we designed a strong antimicrobial,immunomodulatory and regenerative candidate for pulp revascularization and regeneration procedures.
