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.
