Study Notes

Introduction

Difficulty in diagnosing cracks or fractures in teeth due to vague symptoms.
Symptoms can be subtle and last months before accurate diagnosis, often leading to complications.
Definitions:
- Crack: Thin surface disruption of enamel and dentin, possibly extending into cementum.
- Fracture: Split or break in bone, cartilage, or tooth structure.

Classification of Longitudinal Tooth Fracture Types

Crown Originating Fractures
Split Tooth
Vertical Root Fracture (VRF)
Early stages generally show no radiographic manifestations, complicating diagnosis.

Mechanics of Tooth Fractures

Fracture mechanics include:
- Craze Line: Enamel cracks that do not reach dentin; no treatment required unless cosmetic issues arise.
- Cracked Tooth: A crack that typically does not involve pulp; sharp pain while chewing. Management involves protecting the affected cusp.
- Fractured Cusp: A deeper crack; management depends on tooth structure.
- Split Tooth: Longitudinal split separating the tooth into fragments caused by bruxism or masticatory forces.
- Vertical Root Fracture: Extensively longitudinal crack extending through pulp, generally poor prognosis.

Details on Each Fracture Type

Craze Line:
- Etiology: Natural occurrence or post-trauma; common in posterior teeth.
- Diagnosis: Light transillumination.
Cracked Tooth:
- Etiology: Occurs naturally, post-trauma, or extensive restorations.
- Diagnosis: Patient history, biting tests, magnification.
- Management: Bonded restoration or full coverage crown; prognosis varies by extent.
Fractured Cusp:
- Etiology: Extending crack into dentin; visualization can vary.
- Management: Conservative restoration to full crown based on residual tooth structure.
Split Tooth:
- Etiology: Masticatory forces and bruxism; symptoms include sharp pain during mastication.
- Management: Depending on size, may require restoration or extraction; prognosis can vary widely.
Vertical Root Fracture:
- Etiology: Can occur before or after endodontic treatment; risk increases with uneven dentin thickness.
- Diagnosis: J-shaped radiolucencies may be observed; often diagnosed via CBCT.
- Management: Typically results in tooth extraction; generally poor prognosis.

Prevention

Key to managing VRFs includes early diagnosis and minimizing factors contributing to fractures.
Comprehensive clinical, radiographic, and periodontal assessments are essential before endodontic treatment.

Summary

Early detection of fractures is crucial for effective management.
Prevention strategies ought to minimize predisposing factors and be vigilant for symptoms indicative of evolving tooth conditions.
Notably, VRFs are rare in teeth that have never undergone endodontic treatment.
