Summary
Impacted lower third molars are associated with fewer complications in mandibular angle fractures. This suggests their role in fracture stability and reduction, leading to better patient outcomes.
Area of Science:
- Oral and Maxillofacial Surgery
- Trauma Surgery
- Dental Research
Background:
- Mandibular angle fractures carry a high risk of complications.
- The role of the lower third molar's status in these complications is not fully understood.
Purpose of the Study:
- To investigate the correlation between impacted lower third molars and the incidence of complications following mandibular angle fractures.
Main Methods:
- Retrospective study of 68 patients with mandibular angle fractures.
- Patients categorized based on lower third molar status: impacted vs. erupted/absent.
- Complications including malocclusion, limited mouth opening, nerve hypoesthesia, infection, delayed union, and hardware loosening were recorded.
Main Results:
- Overall complication rate was significantly lower in the impacted lower third molar group (27.8%) compared to the erupted/absent group (53.1%).
- No delayed union or hardware loosening occurred with impacted lower third molars.
- A trend towards lower persistent inferior alveolar nerve hypoesthesia was noted in the impacted group.
Conclusions:
- The presence of an impacted lower third molar is associated with a reduced risk of overall complications in mandibular angle fractures.
- Impacted lower third molars may contribute to fracture reduction and stability, potentially improving outcomes.

The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...

Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...
