Summary
This study found that 3.69% of endodontically treated teeth experienced vertical root fracture. Factors like instrumentation technique, post length, and post presence significantly correlated with fracture risk.
Area of Science:
- Endodontics
- Dental Materials
Background:
- Endodontically treated teeth require careful management to prevent complications.
- Vertical root fracture (VRF) is a significant concern in restoring endodontically treated teeth.
Purpose of the Study:
- To investigate the incidence of VRF in endodontically treated teeth.
- To identify factors associated with VRF, including root canal therapy techniques, post characteristics, and retention methods.
Main Methods:
- Clinical and radiographic review of 460 endodontically treated teeth in 303 patients.
- Evaluation of VRF, tooth function, root canal instrumentation/obturation, post type/length/retention, and final restoration.
Main Results:
- A 3.69% incidence of VRF was observed.
- Significant correlations found between VRF and canal instrumentation/obturation technique (p=0.025), post length (p=0.05), and post presence (p=0.05).
- No correlation found between VRF and the retention method of prefabricated posts.
Conclusions:
- The technique of root canal instrumentation and obturation, post length, and post presence are significant factors contributing to VRF in endodontically treated teeth.
- The retention method of prefabricated posts does not appear to influence VRF incidence.
