Summary
Horizontal root fractures are rare in posterior teeth, but can occur in vital teeth, often without obvious trauma. Cone-beam computed tomography aids diagnosis in these challenging cases.
Area of Science:
- Dentistry
- Endodontics
- Oral and Maxillofacial Surgery
Background:
- Horizontal root fractures typically occur in anterior teeth due to trauma.
- Fractures in posterior teeth are uncommon, especially in vital, asymptomatic teeth.
Observation:
- A case of horizontal fracture in the palatal root of a maxillary first premolar with a vital pulp is presented.
- The patient had no recollection of trauma but exhibited signs of bruxism and occlusal erosion.
- Cone-beam computed tomography (CBCT) was instrumental in diagnosing the root fracture.
Findings:
- This case represents one of only three reported instances of vital horizontal root fractures in posterior teeth.
- The etiology remains multifactorial, with potential contributions from trauma and bruxism.
- A fractured root can remain vital and asymptomatic, complicating diagnosis.
Implications:
- Cone-beam computed tomography is a valuable tool for identifying root fractures in posterior teeth.
- Pulp sensibility testing is crucial for accurate diagnosis and treatment planning.
- Understanding the etiology of root fractures in posterior teeth is essential for effective management.

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...

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...
