A vertical root fracture (VRF) is a longitudinal crack originating from the root of a tooth and extending toward the surface. It may be a complete or incomplete fracture. VRFs often occur in teeth that have undergone root canal treatment or have been subjected to trauma.
What causes vertical root fractures?
Here are some of the most common factors that contribute to its development:
- Teeth that have undergone root canal therapy
- Excessive force during procedures like dowel placement
- Direct injury to a tooth
- Chronic habits like bruxism (teeth grinding)
- Teeth with narrow, thin roots
What are the symptoms of a vertical root fracture?
The most common symptoms of a VRF include:
- Discomfort when biting or chewing
- Heightened sensitivity to hot or cold temperatures
- Inflammation or swelling of the gum tissue near the affected tooth
- Development of a draining sinus tract
- Periodontal pocketing
How is a vertical root fracture diagnosed?
A combination of methods are implemented in diagnosis:
- Clinical Examination
- Radiographic Imaging
- Periodontal Probing
- Transillumination
Can a vertical root fracture be treated?
Treatments for VRF include:
- Extraction: Extraction is typically the most viable option, preventing the spread of infection and alleviating symptoms.
- Root Resection (Hemisection): This procedure attempts to maintain some functionality of the tooth.
- Surgical Repair: In select cases, surgical interventions using biocompatible materials to repair the fracture have been attempted.
How can they be prevented?
Consider the following best practices:
- Regular brushing and flossing
- Wearing mouthguards during sports or activities
- Refrain from biting on hard items like ice
- Seek treatment for bruxism
- Choose experienced professionals for treatments like root canals
- Regular dental check-ups
Are vertical root fractures common in root canal-treated teeth?
Yes, they are more common in teeth that have undergone root canal treatment.
Can vertical root fractures cause infections?
Yes, they can lead to infections, serving as pathways for bacteria to infiltrate the tooth and surrounding tissue, resulting in conditions such as:
- Periapical Abscesses
- Periodontal Infections
- Sinus Tract Formation
