Summary
Mandibular fractures frequently involve teeth, with 32% of cases showing root fractures, particularly in third molars. Treatment depends on fracture level and tooth type, with endodontics for salvageable single-rooted teeth.
Area of Science:
- Oral and Maxillofacial Surgery
- Dental Trauma
- Orthognathic Surgery
Background:
- Mandibular fractures are common facial traumas, often involving the teeth-bearing area.
- Fracture lines through dentate segments can lead to tooth crown and/or root fractures.
- The management of teeth within mandibular fracture lines is critical for successful outcomes.
Purpose of the Study:
- To investigate the incidence and patterns of tooth root fractures in mandibular fractures.
- To analyze the treatment outcomes for teeth involved in mandibular fracture lines.
- To determine the prognostic factors for teeth in the fracture line.
Main Methods:
- Retrospective study of 56 patients with mandibular fractures treated between January 2021 and December 2022.
- Inclusion criteria: fracture lines passing through the teeth-bearing area of the mandible.
- Surgical treatment involved open reduction and internal fixation, with specific management for teeth in the fracture line.
Main Results:
- 18 out of 56 patients (32%) had tooth root fractures within the mandibular fracture line.
- Third molar root fractures were most common (66.6%), followed by first premolars (22.2%) and first molars (11.1%).
- Multi-rooted teeth (77.7%) were mostly extracted, while single-rooted teeth (22.2%) were treated with endodontics postoperatively.
Conclusions:
- Tooth root fractures are a significant complication of mandibular fractures, occurring in 32% of cases.
- Third molars are most frequently affected, necessitating careful management.
- Endodontic treatment offers a viable option for salvaging single-rooted teeth in the fracture line, while multi-rooted teeth often require extraction.

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...

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...

The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...
