Summary
Vertical root fractures (VRFs) are common in specific teeth like mandibular molars and maxillary premolars. Factors such as gender, age, and certain clinical signs are associated with VRFs.
Area of Science:
- Endodontics
- Dental Traumatology
- Restorative Dentistry
Background:
- Vertical root fractures (VRFs) are breaks extending along the long axis of a tooth.
- Understanding associated factors is crucial for diagnosis and prevention.
Purpose of the Study:
- To statistically evaluate variables correlated with the presence of VRFs.
- To identify risk factors and common locations for VRFs.
Main Methods:
- Analysis of data from 227 teeth treated by three endodontists.
- Statistical evaluation of factors including gender, tooth location, age, clinical and radiographic findings, bruxism, and pulpal status.
Main Results:
- VRFs are significantly more prevalent in mandibular molars and maxillary premolars.
- Associated factors include periradicular bone loss, pain to percussion, extensive restorations, female gender, and older age.
- VRFs are not necessarily linked to periapical bone loss, widened periodontal ligament space, periodontal pockets, sinus tracts, specific pulpal status, or bruxism.
Conclusions:
- Mandibular molars and maxillary premolars are high-risk teeth for VRFs.
- Clinical signs like pain to percussion and extensive restorations, along with patient demographics, are important indicators.
- The absence of certain radiographic or clinical signs does not rule out VRFs.
