Background and objectives: Establishing apical patency is leaving the apical foramen accessible, free from dentin chips, pulp fragments and other debris.
This in vitro study compared the apical foramen patency for two different instrumentation techniques.
Methods: Thirty single-rooted human teeth were used in this study & the teeth were de-coronated at Cementoenamel Junction.
After that roots were fixed in holes cut through pieces of rubber dam covering plastic containers.
The roots were divided into two groups, the first 15 were instrumented using a step-back technique & other 15were instrumented using crown-down technique.
Both instrumentation techniques were used twice; once without a patency file & the other with a patency file.
Finally the collection vials (the bottles) were weighed after instrumentation, i.e.
with the irrigating solution (the amount of NaOCl + debris that was extruded through the apical foramen into the collection vials) on an electronic balance to the third decimal digit.
Results: By using t-test, there was non-significant difference between the Group A1 (step-back hand instrumentation without use of patency file) & A2 (step-back hand instrumentation with use of patency file) at p> 0.05, with in favor of without use of patency file group.
There was highly significant difference between Group B1 (crown-down rotary instrumentation without use of patency file) & B2 (crown-down rotary instrumentation with use of patency file) at p< 0.01, with in favor of without use of patency file group.
For the instrumentation techniques, the rotary crown-down technique showed lesser debris extrusion than the hand stepback technique both with & without use of patency file, however, the difference was non-significant at p> 0.05.
Conclusions: there is a strong relationship between the patency file & the extrusion of debris & the irrigation solution.
