Pattern of bone resorption in vertically fractured, endodontically treated teeth
1Department of Oral and Maxillofacial Surgery, Tel Aviv University, Tel Aviv, Israel.
Summary
Vertical root fractures in endodontically treated teeth typically cause V-shaped bone loss on the buccal plate. This pattern aids clinicians in diagnosing vertical root fractures during surgery.
Area of Science:
- Endodontics
- Oral Surgery
- Periodontology
Background:
- Vertical root fractures (VRFs) are a significant cause of tooth loss.
- Endodontically treated teeth are more susceptible to VRFs.
- Understanding bone resorption patterns associated with VRFs is crucial for diagnosis.
Purpose of the Study:
- To investigate the clinical presentation of alveolar bone resorption in vertically fractured, endodontically treated teeth.
- To correlate the pattern of bone resorption with clinical symptoms.
Main Methods:
- Evaluated bone resorption patterns in 66 maxillary premolars, 13 mandibular premolars, and 31 mandibular molar mesial roots extracted due to VRFs.
- Recorded symptom type and duration.
- Correlated symptoms with observed bone resorption patterns.
Main Results:
- A V-shaped defect (dehiscence) on the buccal plate was the predominant pattern (91%).
- U-shaped resorption was observed on palatal/lingual plates.
- Buccal plate fenestration occurred in 9% of cases.
- A significant correlation (P <.0001) was found between symptom type and buccal bone resorption.
- Resorptive defects consistently faced the fracture line.
Conclusions:
- A characteristic V-shaped buccal bone resorption pattern is associated with vertical root fractures.
- This distinct pattern can assist clinicians in diagnosing VRFs during surgical exploration.
- Early identification aids in appropriate treatment planning and management.
