Study Notes

Introduction

Diagnosis of cracks and fractures in teeth can be challenging due to vague or specific symptoms.
Symptoms often do not lead to definitive diagnosis; radiographic interpretation may be inconclusive.
Definitions:
- Crack: Thin surface disruption in enamel, dentin, or cementum, of unknown depth.
- Fracture: A split or break in tooth, bone or cartilage structure.

Classification

Types of fractures:
- Crown Originating Fractures
- Split Tooth
- Vertical Root Fracture (VRF)
Early-stage fractures may show no radiographic signs and present slight symptoms for several months.

Mechanics

Fracture types include:
- Craze Line: Enamel cracks not extending into dentin, typically asymptomatic, managed only for cosmetic reasons.
- Cracked Tooth: A crack often found between cusps, with symptoms including sharp pain during chewing.
- Fractured Cusp: Deeper extension of a cracked tooth leading to pain, managed based on remaining tooth structure.
- Split Tooth: Longitudinal fracture dividing the tooth into two parts, often caused by masticatory forces; symptoms involve sharp pain and potential radiographic evidence.
- Vertical Root Fracture: Severe crack along the root's long axis, can extend through pulp to the periodontium; often results from occlusal forces, uneven dentin thickness, or improper endodontic procedures.

Diagnosis and Management

Cracked Tooth Management: Bonded composite restoration or full coverage crown depending on crack extent.
Fractured Cusp Management: Conservative restoration for small fractures, or crown/onlay for larger ones.
Split Tooth Management: Removal of a small oblique split or assessments for restorability in advanced stages.
Vertical Root Fracture Management: Usually results in tooth extraction; prognosis is generally poor.

Prevention

Early detection is crucial; awareness of symptoms as indicators of evolving fracture processes aids diagnosis.
Emphasis on developing a treatment plan that considers potential cracks and fractures during endodontic procedures.

Summary

Prevention is essential in managing vertical root fractures, which are frequently linked to predisposing and iatrogenic factors.
Comprehensive evaluations and historical context are critical before undertaking endodontic treatment or retreatment.
Evidence suggests VRFs are rare in teeth not subjected to prior endodontic treatment.
