Ex-vivo study about antimicrobial effectiveness of phytic acid against Enterococcus faecalis into root canals.

Background: Endodontic failure is due to the persistence of microorganisms, especially Enterococcus faecalis, which have become resistant to disinfection measures. Sodium hypochlorite has been traditionally used, whereas phytic acid, a natural irrigant, needs to be further investigated.

Methods: This ex-vivo study compared the antibacterial effectiveness of 0.

Novel hollow fiber sandwich composite post system: mechanical characteristics.

Background: There is currently no consensus on the optimal post system to provide effective long-term results. We used an engineering approach to investigate the mechanical properties of a sandwich hollow carbon fiber post in synergy with a new bonding technique.

Methods: We studied two systems - a sandwich fiber hollow post (Techole®, Isasan, Como, Italy) composed of carbon fiber incorporated in a Dpp-MOR resin mix and a traditional non-hollow post (Tech 2000®, Isasan, Como, Italy).
