Background: Sodium hypochlorite produces free oxygen and free radicals that
cause damage to dentin collagen. Combination with Sodium thiosulfate with the
aim of improving root canal hygiene and restoring the oxidizing effect on the
dentin surface.The apical third of the root canal is the most difficult part, due to
its narrower anatomy, curvature and frequent branching of the root canal.
Method: The study used 30 specimens which were divided into 3 groups, group
I was irrigated with 2.5% NaOCl, 5% sodium thiosulfate and saline, group II
was irrigated with 2.5% NaOCl, 10% sodium thiosulfate and saline and group
III was irrigated with 2.5% NaOCl and saline. The tooth length 14 mm measured
from apical to crown. The crown down technique was prepared using the M3
Pro gold file. Observation of the level of cleanliness of the root canal was carried
out using a Scanning Electron Microscope (SEM) with 5000x magnification at
apical third . The results of micrographic photographs are then given a score
of 1-4.
Result: Irrigated with 5% and 10% sodium thiosulfate showed no significant
difference.
Conclusion: The differences is not significant, 2,5% irrigation with sodium
thiosulfate resulted in a higher cleanliness apical third of the root canalthan
2,5% NaOCl irigation with saline
