Objective:

To compare effectiveness of ОхОrаl® versus sodium hypochlorite in Enterococcus faecalis elimination at 15 and 60 seconds.

Material and methods:

Material used in the study was 36 E, faecalis ATCC 29212 cultures assigned to two groups: ОхОrаl® and 5.25% sodium hypochlorite. Both groups were in turn divided into 15 and 60 second samples. Samples were placed in peptone water, 1 mL of irrigating solution and 1 mL of strain were left to rest. 1 mL was extracted at each time, samples were seeded into blood agar for 24 hours. Mann-Whitney и test was applied.

Results:

With sodium hypochlorite at 15 seconds, there were three cultures with acceptable growth and six with extended growth; at 60 seconds four cultures exhibited effective result, three acceptable and one extended. With ОхОrаl® there was extended growth in all nine cultures at both established times, significant statistical differences were found at the 60 seconds time (p < 0.01).

Conclusion:

E, faecalis elimination was better with sodium hypochlorite at 60 seconds.
