Role of LSTR in Root Canal Therapy Particularly against Enterococcus faecalis and Enterococcus Faecium

Authors: Aklaqur Rahman Chayon BDS

Endodontic treatment success generally depends on the microbial suppression in the root canal and periapical region. Endodontic instrumentation alone cannot achieve a sterile condition during RCT. Sterilization of bacteria in root canal system is one of the prominent problems. Occasionally Some bacteria could remain in root canal even after using conventional medicaments. Evidence suggested that Enterococcus faecalis (E. faecalis) and Enterococcus faecium caused substantial root canal infections. It is important to evaluate root canal obturation because inadequate obturation may not only produce areas where bacteria may remain and survive, but also provides routes through which bacteria may migrate to the periradicular Tissues. Radiographs have often been used to examine root canal systems and evaluate obturations of the root canal, partly because of its non-destructive nature. Consequently, elimination of such organism is important to achieve Endodontic treatment success. In addition, E. faecalis has been frequently found in re-infected root canal-treated teeth in prevalence values ranging from 30% to 90% of the cases and re-infected root canal-treated teeth are about nine times more likely to harbor E. faecalis than cases of primary infections.
