Purpose:

Cases of vertical root fracture studied to attempt to identify causes and symptoms.

Materials/Methods:

  • N=32 cases of vertical root fracture
  • 32 cases of vertical root fracture examined, records obtained
  • Full flap exploratory surgery was used for diagnosis

Results:

  • in all patients except for 2, osseus defects were present that could be probed
  • 65.63% of patients had only mild pain or dull discomfort
  • 75% showed diffuse widening of PDL
  • excess lateral condensation forces are suggested to cause 84.38% of fractures
  • secondary causes include forcing or tapping inlays or dowels/posts into place
  • 78.13% of patients were older than 40 y/o

Clinical Significance:

Vertical root fractures are often in root canal treated teeth and have associated osseus and probing defects.
