ABSTRACT
INTRODUCTION:
Endodontic treatment removes all pathogens, such as Enterococcus faecalis from pulp and root canals. The aim of this study is to assess the usefulness of sodium hypo-chlorite (NaOCl) in removing E. faecalis from the root canal used with three different irrigation methods. MATERIALS ANDMETHODS:
This study was conducted on freshly extracted maxillary incisors. After biomechanical preparation, root canals were injected with E. faecalis. Three groups were made which contained 30 teeth in each group; 2 mL of NaOCl solution was used for irrigation followed by agitation with K-files in group I; 2 mL of NaOCl solution was used for irrigation and ultrasonic agitation was done in group II. In group III, an alternate irrigation with NaOCl and 3% hydrogen peroxide was done. The fourth group (control) was irrigated with sterile saline solution. E. fae-calis bacteria were sampled to the root canals with paper points and were transferred to tubes that contained 5 mL of brain heart infusion broth. Tubes were incubated and the presence of broth turbidity was suggestive of bacteria remaining in the root canal.RESULTS:
All three groups showed no statistically significant difference. However, difference existed between experimental groups and control groups.CONCLUSION:
The author concluded that all three methods of application of NaOCl were effective in disinfecting the root canal than the saline solution. CLINICALSIGNIFICANCE:
No single irrigant has 100% efficiency. Thus by this study, a best irrigating solution with maximum properties can be established.Palavras-chave
