Evaluate the operative procedures performed in endodontically treated vertically fractured roots and their role in the etiology of the fracture
N= 154 endodontically treated teeth diagnosed with Vertical root fracture
Teeth cleaned and washed following extraction. Teeth, radiographs, clinical findings, and history of restoration placement on teeth were evaluated.
Parameters evaluated were: presence and type of radicular restoration, coronal restoration, and root canal therapy, and the time between coronal restoration and extraction.
- Post present in 62% of cases
- 69% ended in coronal 1/3, 67% were Dentatus (screw type posts)
- 77% had full crown restorations
- 71% of teeth with no posts had obturation considered “acceptable”
- 20% of teeth were extracted w/in 1 yr of crown placement, 55% from 1-5 yrs, and 25% > 5 yrs
Vertical root fractures occur during RCT or post placement, especially screw threaded. Longer posts may be better than short ones. Coronal restorations don’t prevent vertical root fractures but can postpone some of the clinical signs and symptoms that lead to eventual extraction.
