Summary
Mandibular third molars increase the risk of mandible angle fractures. Patients with these molars are 2.2 times more likely to experience angle fractures compared to those without.
Area of Science:
- Oral and Maxillofacial Surgery
- Trauma Surgery
Background:
- Mandibular third molars are anecdotally linked to increased mandible angle fracture risk.
- This study investigates the association between mandibular third molars and mandible fractures.
Purpose of the Study:
- To determine if mandibular third molars are a significant risk factor for mandible angle fractures.
- To quantify the risk associated with the presence of mandibular third molars in patients with mandibular fractures.
Main Methods:
- Retrospective study of mandibular fracture patients (2006-2009).
- Analyzed medical records and radiographs to assess third molar presence and position.
- Correlated third molar status with the occurrence of angle fractures.
Main Results:
- 49 angle fractures occurred in 136 patients with mandibular third molars.
- 3 angle fractures occurred in 18 patients without mandibular third molars.
- Patients with mandibular third molars had a 2.2 times higher likelihood of angle fractures.
Conclusions:
- The presence of mandibular third molars is a significant risk factor for mandible angle fractures.
- Clinical awareness and potential prophylactic measures regarding third molars in trauma patients may be warranted.
