Abstract EN
Background : the aim of the present study was to evaluate coronal leakage of root canals obturated by various techniques.
Methodology : straight single rooted teeth with mature apices (6 groups of 10 teeth each).
Root canals were prepared according to the crown down technique using hand ProTaper system.
Endofill root canal sealer and 2.5 % sodium hypochlorite was used.
Root canals were obturated using cold lateral condensation Thermafil and Soft Core obturation after root canal filling the six groups was divided into two individual groups of 30 teeth.
The first group of 30 teeth was kept for 1 week the second 3 week at 37 oC.
Teeth were immersed in india ink.
Each was split and sectioned longitudinally and the maximum extent of leakage was measured using a stereomicroscope.
Results : leakage occurred whatever filling technique was used the number of teeth with gross leakage decreased with time up to 3 weeks.
There were significant differences in coronal leakage between the various obturation techniques after 1 week, and after 3 weeks.
No statistically significant differences were found between soft-Core and cold lateral condensation after 1 week and statistically significant differences were found after 3 weeks.
There were statistically significant differences between Thermal and lateral condensation after 1 week and no statistically significant differences after 3 weeks.
Conclusion : under the conditions of the present study none of the gutta-percha obscuration techniques prevented coronal leakage.
Coronal leakage increased during the first week for CLC, Thermafil and Soft-Core obturators, and decreased after 3 weeks.
Coronal leakage in the Soft-Core obturators was higher than Thermafil and CLC after one week.
Thermafil coronal leakage was lower than others after one week.
Coronal leakage in the Soft-Core obturators higher than Thermafil and CLC after three weeks coronal leakage was equal in Thermafil and CLC after three weeks.
