Cases of vertical root fracture studied to attempt to identify causes and symptoms.
- N=32 cases of vertical root fracture
- 32 cases of vertical root fracture examined, records obtained
- Full flap exploratory surgery was used for diagnosis
- 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
