Sodium Hypochlorite (NaOCl), E.Faecalis, Root Canal IrrigantAbstract
Background: Elimination of microorganisms from infected root canal is a complicated & difficult task. Elimination or sufficient reduction of irritants, microorganisms and prevention of recontamination of the root canal after the treatment is the essential factor for successes of the treatment. Methods: Following materials required for this study i.e. 36 teeth prepared for root canal inoculation, Enterococcus faecalis strain, 5 % and 10 % carbolic acid solution, 5.25 % sodium hypochlorite solution, phosphate buffer saline and normal saline solution. An overnight subculture plate of E.faecalis was taken for inoculum preparation and uniform suspension made in normal saline (02 ml) by taking up isolated colonies and adjusted to 0.5 McFarland standard which gives 1.5 X 108 cfu / ml. Result and Conclusion: From this study, we can conclude that 5.25 % NaOCl is one of the superior and successful endodontic irrigant against 5 % and 10% carbolic acid.In our study, result shows that sodium hypochlorite solution is superior to carbolic acid solution. However, as this study is in vitro study, not simulate the oral environment; further few clinical studies are required in evaluation of antimicrobial efficacy of these solutions for predictable and successful endodontic outcome.
