Abstract:

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. Endodontic failures would then routinely undergo re-treatment based on the attending clinician's best judgment.A possible alternative treatment for such cases is Lesion Sterilization and Tissue Repair (LSTR) therapy. In vitro antibacterial efficiency of a mixture of ciprofloxacin, metronidazole, and minocycline (3Mix antibiotics), against oral bacteria of children was assessed by Sato et al. The antibiotic combinations were observed to be effective against both carious and endodontic lesions in vitro. Hoshino et al determined that 25 µg each/ml of ciprofloxacin, minocycline, and metronidazole antibiotic mixture to be effective in sterilizing the infected root dentin in vitro. Being such, the antibacterials + MPmixture (3Mix-MP) need only be placed at the orifice of the canal and allowed to penetrate the obturation. By following the prescribed protocol of LSTR therapy, it may be possible to perform an endodontic re-treatment without having to remove the existing obturation. Researches have been and are still presently being conducted to investigate the possibility for such form of treatment to be considered as a possible alternative endodontic re-treatment procedure for certain endodontic failures especially those which are deemed to be caused by viable bacteria remaining within a filled canal of the tooth. chayon26@gmail.com
