Teeth

Teeth

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 and...

Fractures: Bone Repair

Fractures: Bone Repair

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 procedure...

Summary

The absence of an impacted lower third molar may increase the risk of condylar fractures. Conversely, erupted third molars are more common in patients with mandibular angle fractures, suggesting a link between third molar presence and fracture type.

Area of Science:

Oral and Maxillofacial Surgery
Dental Traumatology
Radiology

Background:

The presence of unerupted lower third molars is often hypothesized to increase mandibular angle fracture risk due to reduced bone area.
Conversely, some research suggests a higher incidence of condylar fractures in individuals lacking impacted lower third molars.

Purpose of the Study:

To investigate the association between mandibular angle and condylar fractures and the presence or absence of unerupted lower third molars.
To analyze the influence of third molar position on mandibular fracture patterns.

Main Methods:

Panoramic radiographs were utilized to assess the relationship between third molar status (present, absent, erupted, impacted) and mandibular fractures.
Statistical analysis was performed to determine significant differences between fractured sides and third molar conditions.

Main Results:

No significant difference was found between the condition of the third molar (erupted vs. impacted) and the occurrence of angle fractures (p=0.350).
For condylar fractures, the third molar was absent in 42.9% and erupted in 40.7%, with no significant difference related to the fractured side (p=0.852).

Conclusions:

The findings suggest that the absence of an impacted third molar might be associated with an increased risk of condylar fractures.
The study indicates a potential decrease in the prevalence of mandibular angle fractures when third molars are impacted.
