Evaluation of Penetration Depth of Sodium Hypochlorite Into Dentinal Tubules After Passive Ultrasonic Irrigation Compared to Er;Yag Laser Activation. An In-Vitro Study
Abstract
Objectives: The aim of this study was to compare
penetration depth of sodium hypochlorite into dentinal tubules after passive
ultrasonic agitation or ER; YAG activated irrigant.
penetration depth of sodium hypochlorite into dentinal tubules after passive
ultrasonic agitation or ER; YAG activated irrigant.
Materials and Methods: Twenty-four single rooted human
mature mandibular premolars were decoronated and accessed. After locating the
apex and determining the working length, preparation of root canal was done up
to #35 file using Mtwo system and with 5.25 NaOCl irrigation. Teeth were then
sealed apically with wax and submerged in a crystal violet dye for 48 hours to
stain dentin. NaOCl Irrigation was activated with either Ultrasonic or ER;YAG laser.
Specimens were sectioned longitudinally and depth of bleached zone was
evaluated under a stereomicroscope 40X.

Specimens were sectioned longitudinally and depth of bleached zone was
evaluated under a stereomicroscope 40X.
Results: Penetration depth was significantly
higher in overall root canal in ultrasonic group than ER; YAG laser group (P=.000).
In ER;YAG Laser group, the highest penetration depth was in the coronal third
followed by middle and third, with significant difference between apical third
and both middle and coronal thirds (P=.009, .003 respectively), and no
significant difference between middle and coronal thirds (P=.083).
higher in overall root canal in ultrasonic group than ER; YAG laser group (P=.000).
In ER;YAG Laser group, the highest penetration depth was in the coronal third
followed by middle and third, with significant difference between apical third
and both middle and coronal thirds (P=.009, .003 respectively), and no
significant difference between middle and coronal thirds (P=.083).
Highest penetration depth was seen
in middle third for no significant deference in penetration depth between the
three thirds of the root canal activated with Ultrasonic (P=.664).
Conclusion: ultrasonic activation can lead to more NaOCl
penetration into dentinal tubules than activation with ER;YAG.
penetration into dentinal tubules than activation with ER;YAG.
