Influence of Post Angulation between Coronal and Radicular Segment on the Fracture Resistance of Endodontically Treated Teeth
Introduction: The objectives of coronal restoration in the Endodontically Treated Teeth (ETT) include rehabilitation of aesthetics, function and prevention of coronal leakage. The long axis of root and the coronal segment in the maxillary anterior teeth varies according to the occlusal scheme. T...

| description | Introduction: The objectives of coronal restoration in the
Endodontically Treated Teeth (ETT) include rehabilitation of
aesthetics, function and prevention of coronal leakage. The
long axis of root and the coronal segment in the maxillary
anterior teeth varies according to the occlusal scheme. The
restorative dentist is required to fabricate the post angulation in
compatibility to contour of the adjacent teeth.
Aim: To evaluate the influence of the angle between the long
axes of core facial surface and the radicular segment of the
post on fracture resistance of ETT.
Materials and Methods: Total of 30 maxillary intact canines was
root canal treated, sectioned 2 mm above the CEJ. The custom
made nickel-chromium endodontic posts were fabricated using
direct method. The samples were divided among three groups
of 10 each. The angle between coronal segment and radicular
segment of post in Group-I, Group-II, Group-III were 5°, 10° and
15° respectively. The teeth samples were cemented with full
veneer metal crown and tested under universal testing machine.
The static load at the angle of 130° was applied until the fracture
to record the fracture strength. The obtained data was statistically
analysed with ANOVA and Tukey post-hoc test.
Results: The Group-III showed the highest fracture strength
with 666.15 N. The Group-II and Group-I recorded the mean
fracture strength at 443.37 N and 276.74 N respectively.
Conclusion: The endodontic post with higher angle between
the long axis of facial surface and radicular segment long axis
had the positive correlation to the fracture strength in ETT. |
