“…[ 2 ] Primary infections of the endodontic space are mainly caused by obligate anaerobic species,[ 3 ] while the most responsible one for endodontic failure is Enterococcus faecalis .

Shaping and cleaning a root canal system along with the preservation of the surrounding periodontal tissues are the principal goals of an endodontic treatment. While most of the attention is paid to the mechanical aspects of a root canal treatment, an essential feature of it is the irrigation. All over the years, many materials have been used to clean the root canal of a tooth, and certainly, the sodium hypochlorite (NaOCl) and ethylenediaminetetraacetic acid solutions are the most used and most reliable ones. Putting them inside of a canal is mostly done using a normal syringe, but many techniques have been involved in this process, including the use of sonic/ultrasonic instruments, the use of shaping files, and even laser, to increase the efficacy of irrigant solutions, especially of NaOCl one. Each one of this technique faces some disadvantages, just as the vapor lock effect and the apical extrusion, and has a different action on features such as the reaction rate and the shear stress of an endodontic irrigant solution. In this narrative review, we describe the different features of many irrigant solutions and the different ways of upgrading their efficacy in the cleaning of a root canal system, with the use of tables to summarize the entire description, and drawing the readers’ attention to a photographic illustration for a better understanding of the topic.

Hemp fiber has excellent performance as a renewable fiber material. It is of great significance to study more efficient, energy-saving and environmentally friendly pre-treatment methods of hemp textiles. A novel hemp fiber scouring method based on electrochemical techniques was presented in the research. A type of water solution with high and stable oxidative potential due to in-situ- generated oxidative components was produced by the proposed electrical method, and was applied to scouring treatment of raw hemp fibers by just soaking the fibers in it. Hemp fibers with different treatments were characterized by scanning electron microscopy, Fourier transform infrared spectroscopy and X-ray diffraction, and residual gum rate, lignin content and whiteness of the samples were tested. Experiment results show that electrochemical scouring has a similar degumming effect of hemp fibers compared with traditional chemical scouring, with a better lignin removal and whiteness, implying an effective and short process method of hemp textiles pre-treatment with low impact on the environment.

In mixed biofilms Enterococcus faecalis benefits from a calcium hydroxide challenge and culturing

Abstract: Calcium hydroxide favours the population of E. faecalis in a dual-species biofilm. Culturing multispecies root canal isolates makes E. faecalis detectable. E. faecalis was often present in primary endodontic infections, albeit in low numbers.
